Leon Fou Bartfort

Leon Fou Bartford (リオン・フォウ・バルトファルト) is the protagonist of The World of Otome Games is Tough for Mobs, having died and been reincarnated into an Otome Game he was playing before his death. He is the first Hero of Holfort Kingdom and the guardian of the sacred tree of Alzer Commonwealth.

Appearance
Appearance-wise Leon is a Mob, having plain features that let him blend into the background.

His appearance looks to be similar to the deceased Leon Sara Rault, the little brother of Louise Sara Rault and son of Albergue Sara Rault if he grew up to this age, with black hair and black eyes and average look that felt like it could be found anywhere.

Personality
Leon fully accepts his status as a "mob character" and tries to stay out of the main story of the game (although it doesn't work out that way). He is cynical and has a low view of the kingdom's system that favors women. He has no patience for people that complain from a position of privilege or can't control their egos and he enjoys crushing people like that, both physically and mentally. Despite looking down on overly prideful people, Leon himself is arrogant in his abilities, because he thinks about how his action affect others and doesn't waste an opportunity.

Because of his mob status, he also believes how he doesn't always deserve the praise or affections he earns. This would make him originally try to push away or reject these rewards, including sometimes those he cares about.

After meeting his teacher, Leon gains a high amount of respect for proper gentlemanly behavior. However, this often clashes with his typical attitude.

Despite how Leon initially comes off, he is actually far worse, so much so that even Luxion, who wants to commit genocide of the New Humans tells Leon how cruel he is when he is serious, something that even both Julius and Marie took notice of. Because he saw Pierre as trash, he had no problem pinning a terrorist attack orchestrated by Luxion on him and was happy to take even his noble status away.

However, most of his cruel nature stems from the unfair circumstances he was always given (before and after his reincarnation) and the efforts he had to go through to ensure his own survival both mentally and physically. Overall, he simply wishes to live an easy life.

He is somewhat intelligent, being able to figure out that Marie was also a reincarnated person and coming up with various plans to act as he pleases without getting himself in trouble. He has used this intelligence to also work various favors and plans towards those of higher status than him. He's able to understand the status of his situation and growing power that he plans ways to avoid the troubles that come with it. These results usually end in his favor. He would often use these schemes as a means to live an easier lifestyle.

However, he's not smart enough to realize how much of an influence he has towards others and unintentionally bring himself further away on the simple life he originally desires. This side of him is also shown when it comes to romance where he inadvertently doesn't realize the affections of various girls he earns throughout the series. When it comes to his preferences on girls, he likes big boobs, which is something he does not try hard to hide.

Aside from that, he is also shown to be a caring and kind individual, particularly towards those he feels bad for. Despite how he tries to stay out of trouble and not interfere with the story of the otome world, he would often drag himself at the center of these events for someone's sake (although also seeing it as an opportunity to get back at those who wronged him). When it came down towards those he cares for (like Angelica and Olivia), he is even willing to risk his own life and always tries to think what's best for them. Another example is how he's also willing to take responsibility for his actions such as looking after Olivia, and sometimes the Princes for interfering with aspects of the Otome story that should've been theirs.

In spite of his rather dark personality, he also established a line of morals where he would never try to kill anyone, unless it is absolutely necessary, like in the final clash between himself and the Principality of Fanoss. Another example is when Luxion points out how such an option would give him the easy life he desires, but he always denies such a choice.

Marie, his sister from Leon's previous life points out that he should never be angered and he will corner his antagonists slowly. A good example is shown in his previous life's childhood, where he is being bullied. However, through unknown means he had managed to force all 3 of his bullies to transfer schools within a week.

Previous Life
Leon was originally an ordinary Japanese teenager. He grew up in a normal household with his mother, father and younger sister.

In elementary school, he was bullied by three classmates. However, after several days, one of the bullies came to his house in tears and apologized, but he only responded with a grin, telling his classmate to enjoy his new school. The next day, all three of the bullies ended up transferring for unknown reasons.

Some point in the past, his sister hid her yaoi merchandise in his room, which his mother found. His sister told their mother that it belonged to him and he was unable to convince her otherwise. This incident eventually led to him moving out and getting his own apartment.

Volume 1
His sister would occasionally threaten him for money. Later, his sister blackmails him into completing an otome game of hers, saying she'd explain the truth to their mother if he did. It took him two days straight to complete the game, with the Reverse Harem ending. At the same time, he receives a text from his sister demanding that he complete the game by the time she gets back from the beach, sending him pictures to taunt him. Getting fed up with his sister's attitude, he decided to send the pictures to their mom as proof that his sister is misusing her money. He then decides to leave his apartment, but gets hit with a wave of dizziness from exhaustion before he falls down the stairs and seemingly dies.

He then wakes up as a five your old Leon Fou Bartford, with memories of his past life coming to him like a dream (with the exception of his name), alone in a field. After collecting himself, Leon goes back to his home, only to be reprimanded by his father for wandering off. Zora then arrives with her children and lover. Irritated by Leon's behavior, Zora sends him, and his brother Nicks to study in the storehouse, and out of the way cabin in the woods. While in the storehouse, Nicks explains the situation of their family and how women hold more power than men in their society. After the explanation, Leon realizes, to his horror, that he is stuck in the otome game he had been playing.

10 years later, Leon is suddenly told that he won't be going to the academy and will have to marry the daughter of one of Zora's associates. Leon and his father are against the idea, but have a hard time convincing Zora. After a debate, Zora agrees to call off the marriage under the condition that either Leon or Barcus gets her the money she would have made from it. After Zora leaves, he tells his father that he wants to borrow an air-boat, intending to become an adventurer to earn the money.

After a month of adventuring, Leon manages to find a warp device that he remembered from the game. While he loses his ship, Leon manages to get through the warp device, landing on a floating island that holds a special lost item. After destroying a robot, he took the path he remembered from the game. He comes upon a lab with several corpses, and realizes that the corpses name tags use the alphabet from the earth. Deciding to focus on getting the item, he proceeds deeper and, using a security card from one of the corpses, enters The Dock of the Lost Items. He then finds the Ancient Spaceship he was looking for. He enters the ship and explores for a bit before finding an automaton, which proceeds to attacks him. After Leon is captured, the automaton explains that its purpose is to exterminate the New Humans. Leon manages to defeat the automaton, and proceeds to the control terminal of the ship. He is surprised to see multiple earth languages, including Japanese. The automaton notes that new humans should not be able to read any of those languages and Leon explains that he was Japanese before his reincarnation. Leon takes control of the ship, and the automaton recognized him as having Old Human (specifically Japanese) blood. He names the ship Luxion and explains how the world is an otome game. Leon then passes out from his injuries. Two months later, Leon returns home on the Luxion, greeting his family (and an angered Zora). After getting back, Zora demanded that he hand over all of his lost items and treasures, but Leon refuses, as an adventurer had all right to whatever they find. Sometime later, Leon discovered a deserted island. Seeing that it, at best, could reach the level of a baronetcy, he declared his independence and claimed it as his territory. Luxion now follows him around as a levitating gray camera.

Before entering the academy, Leon is surprised to find out that he will be entering the advanced class despite being the third son of a lesser noble. His father explains that this is due to his adventuring success and that he will be the baron of his own house after graduation. Leon complains about being in the advanced class, considering the women in that class as "minefields".

At the school welcoming party, he meets Daniel, Raymond, and Rukul, who explains to him how well known he is. At the assembly the next morning, he overhears a girl mention waiting for the princes. Looking at her, he feels a sudden rush of anger, which he can't understand the reason for.

Leon stays in the background for a few weeks. While planning a tea party with Daniel and Raymond, they see a small argument between Angelica and Julius, centered around Marie. Throughout the argument, Leon comes to realize that Marie has somehow taken the place of Olivia from the original game. Later, Leon is spacing out in etiquette class and gets called out by the teacher. The teacher then asked Leon to come down to help him demonstrate a proper tea ceremony. After the demonstration, Leon is blown away and moved by his teacher's gentlemanly behavior and accepts the teacher as his master. Later that day, he invites the second daughter of a baron to participate in a tea ceremony he is holding, but the girl unexpectedly shows up with her friends and their servants. Despite his effort, the girls only considered his tea party a time-killer before they went to another party after eating most of his prepared sweets. Before he has time to clean up, he overhears the girls yelling from outside the room. He walks out just to see them walking away from Olivia after ripping up an invitation to a tea party she had received. Feeling bad for Olivia, he decides to invite her to his own tea party. Olivia accepts and is much kinder and considerate than his previous guests. Olivia admits that she is having trouble in the academy, and Leon says he knows someone who can help. They approach his sister Jenna, who tells them that Olivia should send a gift the highest ranking member of their class, Angelica, to ask for a meeting. Leon begrudgingly agrees to pay for the gift.

Several weeks later, Leon, having been recommended by Angelica, is sent into the dungeon as a guard for the Prince and his entourage, along with Olivia, Angelica, and Marie as part of a class lesson. He and Olivia partner up, but are interrupted by overhearing yet another argument between the prince and Angelica about Marie. Realizing that Marie has taken Olivia's spot again, it's at this point that Leon starts to become suspicious of the girl.

Leon and Olivia are sent as vanguards ahead of the other students. After looking around for a bit, Leon and Olivia encounter some giant ants. Leon slays the ants with a sword created by Luxion quite easily, but is caught off guard by a monkey and it bit on the arm. After he kills the monkey, Olivia heals him and the two continue. They eventually reach the third floor, with Leon having collected a full bag of magic crystals. A few days later, Leon is hanging out with Raymond and Daniel, and the group complains about not being able to find girls to marry them. Raymond then mentions that rumors have started that Angelica has been the one behind Marie's bullying, much to Leon's surprise. He recalls a similar event in the game, but it was not supposed to happen for much later. Later on, in the library, he asks Olivia about Marie. After learning that Marie has been especially cold to Olivia, the two overhear flirting behind some bookshelves. They check it out and both are shocked to see Marie kissing Brad.

The next day, Jenna bursts into his room. She asks Leon about Marie, and he confirms that he's heard rumors of her being friendly with the prince's group and that she's being bullied by Angelica. Jenna then clarifies that if Angelica was really trying to crush Marie, then she wouldn't still be alive. She then goes on to explain that it is important how the school views Julian as he is next in line for the throne, before demanding that Leon should stay out of Julius and Angelica's way during the End-of-Term Party, as to not cause trouble for the family. After she leaves, Leon sends Luxion to confirm whether the rumors about Angelica and Marie are true or not. Luxion gets back to him and gives him enough information for him to conclude that Marie was reincarnated like he was. At the End-of-Term Party, Leon, Daniel, and Raymond all agree to do their best to find girls to marry them, but none have any success. The group then goes to mourn their failure in the courtyard. A short time later, Olivia comes out, telling Leon to come back inside. When they arrive back in, Olivia explains that an argument between Julius and Angelica is escalating. After Angelica challenges Marie to a duel and the prince and his group decide to act as Marie's representative, Leon initially does not want to interfere, but quickly decides to fight the group out of pure hatred of them. He walks up to the prince and offers to participate as Angelica's representative, which she agrees to. Leon then goes on to mock the group, taking joy in Marie's surprise. Leon then asks Angelica's intention in inviting the duel. She tells him that she just wants Marie to stay away from Julius. Marie states that she wants the fighting to stop and after the conditions are set. Jilk states that the duel will be five one-on-one matches. Leon agrees before taunting the prince directly.

Afterwards, Leon returns to his room, only to find that it has been vandalized. Luxion then shows him how heavily people are betting against him in the match. Leon responds by telling Luxion to bet 500 platinum pieces on him.

The Next day, Angelica has the teachers prepare a room for her to speak to Leon alone. She asks him to withdraw from the duel, only for him to explain that his image won't improve even if he did. She explains that her room was also vandalized and that her family wasn't helping her, so he has nothing to gain. Leon then tells her that he wasn't trying to get on her family's good side and admits that he just wanted to beat them up. She asks him about how it will affect his family, but Leon explains that, as he is technically an independent knight, his family isn't involved at all. Leon goes on to tell her that he is confident that he can win.

The Day of the tournament comes and, after a short talk with Olivia, Leon walks into the arena. As he walks in, Leon is greeted by a series of hecklers. He's happy to see that Raymond and Daniel bet on him. Leon is then confronted by Angelica, who asks him where his armor is. Right after, Arroganz lands in the center of the field. Arroganz's appearance is met with laughter from the crowd due to its size, but Leon ignores them as he gets in the armor. Brad steps up to be his first opponent. Leon summons a shovel form Arroganz's backpack to be his main weapon, inciting more laughter from the crowd. As the match begins, Brad charges at Leon, but Leon quickly disarms him before knocking him unconscious with a single hit to the head. This surprises everyone, including Leon himself. The next opponent is Greg, who charges at him with a flurry of attacks. Leon blocks all of them before getting angry at Greg for being too prideful to use proper equipment(in the game). He pushes Greg off of him and proceeds to brutally attack his armor, tearing it apart. Greg states that he's only winning because of his armor, and Leon mocks him for making excuses. Greg then exits his armor and tries to take on Leon with a piece of scrap metal. Leon mocks his weakness and is declared the victor. Leon's third opponent is Chris. Leon begins by launching drones to attack Chris from every angle, ignoring Chris's complaints about Leon's lack of chivalry. Leon then mocks him, causing Chris to charge, but Leon easily catches his sword, snapping off the tip of the blade. Chris falls to his knees in despair, and Leon again mocks him. Leon wins his third match.

During the break before his next match, Leon runs into Angelica and Olivia. The two tell him that Jenna had asked them to check on him. Luxion then informs him that Jenna was instructed to put place a bomb on Arroganz by Jilk. When the battle begins, Jilk starts by creating a smokescreen before sniping Leon with armor piercing shells. Seeing as the shells were ineffective, Jilk detonates the bomb. The bomb also proves ineffective as Leon quickly flies up to his opponent and attacks him. Jilk claims that fighting the prince will result in Leon losing his titles, but Leon is happy as long as he has his freedom. Desperate, Jilk states that he'll do everything he can to hold Leon's family responsible. Unfortunately for him, Leon recorded his threat and then played it back for Jilk to hear, using it as blackmail material to keep Jilk away from his family. Leon then slams Jilk into the ground, heavily injuring him knocking him unconscious.

Before his match with Julius, Leon asks him what he thinks about Olivia, but the prince gives an underwhelming answer. The match begins with the two throwing attacks at one another. Leon notes that Julius has more spirit than the others, and asks him what it's like to truly love someone. Julius replies that Leon and Angelica should just stay out of other people's business, leading Leon to come to understand why and how Julius fell in love with Marie. Julius then asks if Leon find looking down on and lecturing others as fun, to which Leon happily responds that it does and that his arrogance is deserved. Leon states that he doesn't care about the prince's problems and openly complains how difficult it is for an average person to find a decent wife, earning him respect from some male members of the crowd. Leon's opinion of the prince lowers even more as he realizes that Julius has not even considered how his actions could affect the kingdom. After beating down Julius, Leon tells him to apologize to Angelica, but Julius refuses. Using his authority as the prince, Julius orders the duel be to the death. Leon states that he could have killed Julius already if he wanted to and explains that even in a deathmatch, Leon would get punished for killing a prince, so his only option is to resign. He goes on to mock Julius using his title as a shield despite complaining about it earlier and asks what's the best way for him to forfeit. Leon's insulting attitude towards the prince earns his ire from the crowd. Leon tries to explain how choosing Marie over Angelica would probably cost him his right to the throne. The prince says he doesn't care. Leon then uses Impact to destroy his armor and knock him unconscious.

Leon is declared the winner of the match, receiving hatred from the crowd. After exiting Arroganz, Leon has a short conversation with Angelica and Olivia before Angelica goes to check on Julius. Leon then tells Olivia that he's expecting to get expelled for what his done.

Later, Leon approaches Vince & Gilbert Redgrave. He offers them the money that he won from the match in exchange for protection, which Vince agrees to. Vince questions if Leon is willing to give up his rank and title to which Leon responds that he is. Gibert asks his true motive is in giving up all his accomplishments. Leon considers telling the truth, that he wanted to beat up the princes and not have to worry about marriage any more, but he instead lies, telling Gilbert that he did it for the sake of the country, as the prince was being manipulated. Vince agrees with his reasoning and explains that he has called off the engagement between Angelica and Julius, no longer seeing the prince as worthy of being with his daughter. Vince then concludes that he is sending Angelica to recover from her broken heart at Leon's household. Leon leaves, overjoyed that he is now protected from execution and can escape the academy, marriage, and even his nobility.

Several days later, he's on the airship heading towards him home. Luxion tries to get Leon to talk to Angelica and Olivia, but Leon believes that he can't help her, so there's no point. He later overhears Angelica and Olivia talking about him and learns that they believed that he didn't want to be expelled and took it for Angelica's sake (which isn't true).

Volume 2
Before the school festival, Jenna, with Meiol in tow, go to Leon's cafe before it opens, hoping to get Leon's help with a problem: she and her friend are after the same boy, and Jenna wants Leon to make her friend back down despite her friend liked him first. Leon, seeing that Jenna is the bad guy in the situation turns her down, and Jenna and Meiol leave.

During the school festival, Leon opens a cafe along with Angelica, Olivia, Raymond, and Daniel. Unfortunately, they have very little success as Marie and the prince's entourage open a competing cafe next door to them. Eventually Angelica has to leave and the cafe receives an Earl's daughter along with her followers and servants. Leon initially puts up with their rude and demeaning behavior until Angelica walks in with the queen. Instantly recognizing her, Leon, using the fact that the earl's daughter insulted her as an excuse, uses the opportunity to take out several of the girl's follower and force her to leave.

Volume 4
Leon, along with Marie and the Prince's Entourage, transfers to Alzer Commonwealth to make sure that his actions have not affected the plot of the second game.

After transferring, Leon is provided with a small house to stay in and becomes friends with his classmates Noelle and Jean. He later meets Louise and is confused by her affectionate attitude towards him. After Pierre assaults Jean, Leon wanted to get revenge, but held back knowing that it could cause political trouble. Later on, when the prince's entourage lose Einhorn to Pierre, Luxion seemingly switches sides. Quickly figuring out Luxion's plan, Leon, along with Noelle (whose been harassed by Loic) move in Marie's mansion.

Bartford Household
Leon gets along well with his father as he tries not to involve him or his family into trouble. When Leon wanted to be an Adventurer, Barcus went out of his way to get Leon a ship and various other gear for Leon to survive his life adventuring for fortune. Barcus was also quick to execute Meiol, when he found out his daughter's servant had tried to get Leon killed.
 * Barcus (Father):

She cares for her son's well being. When Leon was being promoted she initially believed her son to be stupid and was genuinely crying tears of joy from his success.
 * Luce (Mother):

Leon gets along well with him, feeling sympathy for Nicks horrible time being married.
 * Nicks (Older Brother):

Despite seeming to be rude and demeaning to one another most of the time, the two seem to have a decent sibling relationship. Leon likes Jenna enough to buy her a slave and Jenna likes Leon well enough to tell him the in's and outs of the Academy hierarchy. However, she still placed a bomb onto Arroganz, albeit being forced and being worried for her brothers' safety during his match with Jilk Fia Marmoria. However, a good sign of their relationship was that Leon easily forgave her for planting the bomb and was particularly brutal in his match against Jilk for making her do it.
 * Jenna (Older Sister):

*Information will be added soon later.*
 * Finley (Younger Sister):

Colin looks up to his older brother.
 * Colin (Younger Brother):

Zora's Side of the Family
Leon does not like anyone on that side of the family.

Lovers
While playing the game, Leon viewed Olivia as a sly girl who was manipulating the characters, but after meeting her in person and seeing her kindness, his opinion of her changed. At the same time, he unintentionally became her first friend at the academy. They spend so much time together that Leon would come to Olivia's defense on her behalf when it comes to bullies and adventuring. This relationship improved to where Olivia wishes Leon to affectionately call her Livia. When Luxion explained that Leon's involvement had actually hindered Olivia's development, he became somewhat depressed. This feeling grew even more when Livia snapped at him on why he keeps helping her, making him realize if he was really seeing Livia as who she is besides being the protagonist of the Otome game. He then tried to distance himself from her in an attempt to push things in the direction of the game and even calls her by her original name, Olivia. They eventually make up during the school trip and battles against the Principality where she ends up confessing to Leon and he once again calls her Livia. As the story progresses they both spend more time with each other leading up to Leon inadvertently capturing her heart and getting engaged with her. While initially reluctant, Leon is very happy of his current relationship with Livia and tries his best not to upset her or Angelica, particularly on matters relating to cheating.
 * Olivia

Leon's first interaction with Angelica was when he offered to become her representative to fight the princes (though it was out of hatred for the princes rather than any level of kindness). After the match, the two of them become friends. As the story progresses Angelica spends more time with Leon as after the duel with the prince and his group many people try to regain her favor after abandoning her leaving her to hang with Leon and Olivia who she took a liking to as she could trust them. After both suffered a similar feeling of guilt towards Livia because of their respective status, they all originally ended up distancing between themselves. It was during the school trip that they somewhat mended their relationship and when Leon saves her from the Principality, their relationship improved to where Angelica falls in love with him. Leon would also inadvertently grow closer to her to the point where he, originally reluctantly, and gets engaged with her. He's now very happy of his relationship with Angelica and tries his best to be faithful to her and Livia.
 * Angelica Rafa Redgrave

Holfort Academy
During his match with the princes, many people place high-cost bets against him. When Leon won the match, this resulted in most students in the school losing a large amount of money. This single event made Leon the most hated person in the school. Though this is a small group of boys who look up to him for openly revealing some of the problems they have to deal with in their women favoring society.

They're enemies. Leon easily reads through her manipulation of the princes and realizes that she, like him, was reincarnated. He gets a rush of anger whenever he sees her. As the story continues on Leon does not pity the situation Marie has gotten herself in, messing with the story, stealing the role of Protagonists and capturing the game's target (The Prince and his entourage) all for it to come crashing down as leaving her broke. In volume 3 her relationship with Leon improves as both figured out that they were siblings before they were reincarnated resulting in Maria begging Leon to help her like how he used to do before, leaving their relationship in a somewhat better state than before both pre and post reincarnation. Now, he gives her an allowance and feels pity for her situation with the prince and his group(though he still sees it as her own fault).
 * Marie Fou Lovan (Former Sister)

Their newfound closeness and familial interactions have caused several characters to suspect that she and Leon had become romantically involved, an idea that Leon finds both disgusting and annoying.

Leon's male friends that he met at a welcoming party when he first enrolled. They all faced similar situations in regards to finding an ideal marriage partner but often get disappointed where either most of the good girls are taken or for their terrible personalities. Although they originally abandoned Leon when he acted as Angelica's representative in a duel against the Prince Entourage, Leon didn't hold it against him. However, they both have bet on Leon's victory which expresses their fair amount of trust in him. After the duel is over, Leon still hangs out with them where they're usually hang out like at his tea parties.
 * Daniel Fou Dalant & Raymond Fou Arkin

Leon has kept his overall good relationship with both of them even though both became jealous of Leon's relationship with Olivia and Angelica. Leon establishes a business relationship with them by giving them the airships he stolen from the Principality of Fanoss during the school trip, and being in charge of their maintenance and repairs.

A noble woman who Leon met during his school trip when the Principality of Fanoss attacked their cruise ship. Leon used her and the rest of the students by coercing them into fighting the Principality. While Deirdre originally looked down on Leon for his crude behaviors and actions, the event made her garner interest in him. When Leon shares a conversation with her, he becomes shaken and finds her hard to approach when Deirdre expresses her love interest in him such as eloping or taking him in her household.
 * Deirdre Fia Roseblade

The two originally had an antagonistic relationship with each other when Leon was against her during the air bike track race. However, Leon didn't exactly hold anything against Clarice as he was aware of how she was more of a victim after her broken engagement with Jilk. When Leon learns more about Clarice through one of her servants, he decided to have both Jilk and Clarice confront and make amends with each other. This has Clarice see Leon in a better view where they now share a rather close relationship where she has attended in his tea parties and even sent him a custom bike from her household. Unknown to Leon, he also gains her attention romantically.
 * Clarice Fia Atlee

One of Leon's classmates who shared a similar status in their nobility when he first enrolled. Rukul praises Leon for his efforts in adventuring which made Leon regress to a state of desperation on how he only did it to save his livelihood. The two haven't interacted much since.
 * Rukul

Leon highly respects his teacher, finding him as the perfect gentleman. They have an amicable relationship.
 * Master (Teacher):

The Prince's Entourage
Leon has disliked the group ever since he played the game. He found them all arrogant despite being incredibly weak and useless in battle. His opinions of them worsened after meeting them in person. However, he gains a small level of respect for each of them after the war, but he still sees them all as idiots.

Leon considers the prince a hypocritical idiot. He's annoyed by the prince is so dead set on making Marie his wife while not taking how that will affect the kingdom into account. Leon's also annoyed that Julius as beautiful girls of high standing throwing themselves at him while most boys have to beg girls to marry them. He also sees Julius as a hypocrite, as, during their match, Julius complained about the troubles of being a prince only to later use his authority as a prince as a shield against Leon.
 * Julius Rafa Holfort

Leon dislikes Jilk. He finds Jilk's trope of being the quiet one who's actually the most dangerous as overused and boring. Leon's opinion of Jilk worsened when Jilk made Jenna put a bomb in his armor and he was especially brutal during their match.
 * Jilk Fia Marmoria

Leon sees Brad as an arrogant narcissist. However, Leon develops a begrudging respect for him after Greg and Brad protect Olivia from a sky pirate.
 * Brad Fou Field

Leon originally saw him as a knight who valued his sword over actual strategy in combat and found his chivalrous attitude annoying. However, Leon gained some respect for him when he helped Leon rescue Angelica from the Principality.
 * Chris Fia Arclight

Leon initially thought of Greg as an over prideful idiot who couldn't use his equipment properly. However, Leon develops a begrudging respect for him after Greg and Brad protect Olivia from a sky pirate.
 * Greg Fou Seburg

Others
Leon gets along with Mylene. Despite her already being married with a child Leon's age, he wouldn't mind marrying her and often flirts with her by instinct.
 * Mylene Rafa Holfort

Luxion is a cheat item Leon found in a dungeon in his attempts to avoid a marriage that was set up by his family. He knows of Luxion's existence when he played the Otome game and used this knowledge to find the A.I. Originally, Luxion saw Leon as an intruder and among many "new humans" who attempted and failed to obtain the A.I. When Leon reveals his Japanese and reincarnation origins, Luxion submitted to him when Leon managed to take control over the cheat item.
 * Luxion & Clare

The two have since established a trust-hate relationship with each other where although Luxion is obedient towards Leon, the two would often argue and throw insults at each other. Leon would often consult to Luxion for advice when facing certain crises, but not always concede to the cheat item's suggestion such as destroying the new humans. They have established a deep trust with each other that even when Luxion was taken from Leon during his time at the Alzer Commonwealth, he wasn't shaken by Luxion's betrayal and actually became aware of the A.I.'s intentions and played along with its plans. Leon still often gets very irritated on how Luxion would tease him or put him in unfavorable situations, particularly in matters on his romantic relationships.

Clare is a by-product of Luxion to protect and communicate with Olivia and Angelica when Leon had parted from the two. Clare appears kinder and subservient to Leon when it comes to his orders but is not above the methods on how it carries those orders.

The two share a bitter relationship where they both have downright admitted their distaste for one another. Because of Leon's achievements and actions, Roland has acknowledged his skills but finds it infuriating on how he has to deal with the issues and aftermath. He also dislikes Leon showing him up during the war. Leon, on the other hand, realizes how Roland is involved in his promotions and unfavorable situations, which further deepens their dislike for one another.
 * Roland Rafa Holfort

It's worth noting that their dislike of one another has nothing to do with Leon's flirtation with Mylene.

The two of them are completely complicated. At first, she is very vigilant but sometimes she acts too friendly to Leon. She is also ready to give him the position of the Duke because she thinks he hates the nations' inequality and ranking discrimination of the noblewoman. But after several days of knowing each other, the girl has shown some hints of being in love with Leon.
 * Hertrude Sera Fanoss

Leon doesn't hide his desire to help the girl. He often shows her a genuine treatment of a good master and Yumeria returns him with loyal but sometimes troublesome service.
 * Yumeria

The two originally seemed to have a neutral relationship, with neither one really caring about either way. However, after Leon injured another servant, Meiol grows to dislike him and was willing to frame Leon for a crime out of pure spite.
 * Meiol

Alzer Academy
They became acquainted and established a friendly relationship with each other. After seeing his good qualities and how he keeps on saving her, Noelle develops feelings for him. Leon is unaware of this and only sees her as a friend and an important individual he must watch over as the second Otome game's protagonist. He becomes aware of her feelings when she's forcibly engaged to Loic and rejected his rescue and Marie telling him. He was torn and guilt-ridden upon this revelation but support-talk from the Prince Entourage made him realize he wants to save her no matter what. After Leon rescues Noelle, they managed to mend their relationship to what Leon sees as "More than friends, but less than lovers" and states further progress is impossible.
 * Noelle Zel Lespinasse

Marie says Leon's feelings and actions for Noelle are out of care and pity, while Luxion states that the two may have feelings for each other.

Upon meeting him, Leon has good terms with Jean. He is always acting like a brother-in-arms to his buddy and he is ready to take vengeance against his enemies who are treating him badly.
 * Jean

Louise is incredibly kind and affectionate towards Leon due to his resemblance to her deceased younger brother. It's implied in Volume 5 that she might be developing romantic feelings towards him.
 * Louise Sara Rault

The two share a mutual dislike towards one another. Leila dislikes how Leon's presence ruined her plans and if frightened by Leon and Luxion's power. On the other hand, Leon dislikes how she puts the progression on the game over Noelle's happiness. That, being the case, they are still willing to work together to keep Alzer safe.
 * Leila Zel Lespinasse

A teacher of him while studying aboard in Alzer Commonwealth. He finds Leon cute.
 * Clement (Teacher):

Leon gained a hatred for him after he assaulted Jean which grew deeper after he stole Luxion. During their match, Leon showed him no mercy: brutally assaulting and embarrassing him, stopping Pierre from surrendering, framing him for a terrorist attack, and having his crest taken away.
 * Pierre Io Faiviel

Their first meeting was Leon hitting Loic with Luxion to get him to stop harassing Noelle and their relationship only got worse from there. When Leon crashed the wedding, he made a point of calling Loic out, which led to their fight.
 * Loic Leta Barielle
