Leon Fou Bartfort

Not to be confused with Leon (Alzer). Leon Fou Bartfort (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 in an Otome Game he was playing before his death. Leon is a distinguished Marquis and a renowned hero of the Holfort Kingdom also the Guardian of the Sacred Sapling of Alzer Republic.

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.

In Marie Route, he bears faint resemblance of his distance ancestor Lea Bartfort, enough for Anne's spirit to notice almost immediately.

Personality
The first impression any outsiders can make of Leon Fou Bartfort is being cynical and has a pessimistic view of the kingdom's system that favours women. He has no patience for people that complain from a position of privilege or can't control their egos, as well as crying girls. Despite looking down on overly prideful people, Leon himself enjoys showing arrogance in his abilities, because he knows about how this display of superiority damages his opponent's confidence & pride, therefore he doesn't waste an opportunity to crush his adversaries mentally.

Most of Leon's cold-hearted actions and antagonistic behaviours 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. When it comes to his preferences on the opposite sex, he likes voluptuous women with developed bosoms, something Leon is not very subtle about.

After meeting his Master, Leon gained a huge amount of respect for the gentlemanly behavior his professor has shown him. Leon is still working on to imitate him through practicing the art of tea, and hope to reach his master's standard. However, at times where the girls in the academy treated his efforts as non-existent and trampled all over his hard work in tea making, Leon may doubt whether his path of tea is misdirected.

Leon is situationally quick-witted, being able to pickup hints about Marie being a reincarnated individual within months of joining the academy and thus tried to come up with various plans to act as he pleases without getting himself in unfavourable grounds. The second Bartfort son is aware of his increasingly-troubling situation and growing power; thus he makes sure to have course of actions to avoid the complications that come with it. He would often use these schemes as a means to live an easier lifestyle. Despite being quite a schemer, Leon is not someone with political skills and he does not act thinking about political consequences, often leaving it to Master, Angelica and Queen Mylene to clean up after his deeds.

Aside from that, Leon is shown to be a caring individual, particularly towards those he feels bad for, the second Bartfort son also is the type of person who will take things very personal and holds grudge against people who dared bad-mouthing his loved ones. 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. 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 Prince's Entourage for interfering with aspects of the otome story that should've been theirs.

Psychological Profile
Often outshined by his incredible physical and material feat, it is arguable that the Bartfort second son's trump card lies in his intellect. Leon has lived two very different lives in two completely different worlds, and being in a nation that value independent adventurers. Essentially gifted with wisdom vastly preceding his physical age, Leon understands the importance of abusing his resourcefulness to gain an upper hand. If given an opportunity to get back at people who had wronged him, Leon — being a pragmatist — would gladly take full advantage of the situation, combining new factors to his original master plans to ensure maximum damage (both mentally and physically) inflicted on his adversaries.
 * Patterns of Behaviour

"Do all of you seriously think that guy (Leon) will obediently come out into this situation to get slaughtered just like that? Believe in that guy! That guy... isn't a man who will show up to this kind of place without any plan. He is a guy who will have thoroughly prepared to push off this enemy to the very bottom persistently" - Marie Fou Lafan

It is to be assumed that unless it is of Leon's direct consent, there is no such thing as a fair fight when going against him, as he is a person who would prefer to engage in asymmetrical battles that stack the deck in his favor as much as possible to ensure his victory. He is street-wise enough to consistently out-maneuver his opponents; beside he would almost never put himself in an unfavourable position (made easier with Luxion's information-gathering capability) under the virtue of "Preparation is half of the fight". Case in point, Leon while officially behind prison bar and blamed as a traitor was able to (in collaboration with Master and Queen Mylene) orchestrate a counter coup and dismantlement of Frampton's political faction.

"I told you before. I'm a coward... I will only fight a battle that I can win" — Leon taunting Pierre.

Having lived in modern society, Leon does not pay too much care to qualities like honour or chivalry. If it is what must be done, he pulls no punch in the way of deceptions and underhanded tricks against his adversaries, taking inspiration from Luxion's quote when he first fought against the AI. "Being called a coward is the highest praise in the battlefield". This is evidence when he walks in the sacred duel seemingly bare-handed while having already laid the groundwork for both Pierre's public humiliation and the strategic air raid against Feivel House's territory. Occasionally, Leon utilise misinformation to manipulate the surrounding's mood toward a direction he desires (He had no problem pinning the Feivel air raid on Pierre, and has multiple time shift achievement credits to other people).

His previous life sibling, Marie, also noted that although normally Leon is a composed individual, there is a line that under no circumstances anyone should cross in order not to anger him. An infuriated Leon, instead of exploding in an frenzy of outrage, will silently and calmly corner his preys. A good example is shown in his previous life's childhood, where he is being bullied; it is assumed that he was able to inflict serious mental trauma towards the bullies, resulting in their school transfer few weeks later. His close confidents such as Luxion, Marie and Julius are fully aware of just how cruel Leon can be when he takes business seriously, acknowledging Leon as a thorough schemer.

In contrast to his seasoned intellect, Leon has an easily exploitable mentality of a 21st century adult. In spite of displaying outwardly as a greedy antagonistic coward, Leon deeply values human lives more than anyone else around him. He spared the Black Knight in their first duel, despite fully knowing their relentless destructive motive, a mistake that was later exploited by Vandel, resulting in a second, much bloodier rematch. During the operation to subjugate air pirates, Leon went through great length to capture and secure prisoners while Luxion stating it was unnecessary and create complications. Additionally, the second Bartfort son shows vocal distaste about Luxion's philosophy of total annihilation and mass atrocity and would repeatedly order the AI to forget about that directive.
 * Morality

While restraining whenever possible, when backed into having no other option, Leon will absolutely cut down anyone deemed a threat to the people he cares about, like in the final clash between himself and the Principality of Fanoss. Having participated many battles and saw many whom have fallen, Leon felt deeply responsible for each and every lives lost along the way. A result of his modern mindset, this also makes him more vulnerable to PTSD, depression and CSR as being born in peaceful era he is not well-equipped when dealing with casualties. Even with Pierre, he felt guilt at the thought of the guy being tortured by his family until eventually put to death. Rationally Leon still accept his action as a correct decision, but the fact that he felt guilt for Pierre (who was notorious in Alzer as a violent rapist murderous scumbag) says a lot about him not doing well with killing/death. It can also be noted that his PTSD and mental issues has been increasing ever since he was forced to commit mass murder against the principality in order to survive, and Luxion has been offering sleeping pills in order to ease Leon's depression to little avail.

"The war? I don't have any. In the first place, I was born during a period of peace, and I was an office worker there. I don't have any experience in war... Now that I think about it, my previous life was quite the blessing..." — Leon explaining his background to Luxion.


 * "Mob mentality" and "Imposter syndrome"

Leon fully embraces to his status as a "mob character", he is constantly under a dilemma of balancing between non-interference to the world's plotline and protecting the ones he cares for from imminent destruction. It is currently unknown that whether this mindset existed in his previous life, or it manifested and became one of his core traits during his second life in the otome game world. Leon prefers to think of the original otome storyline as "what could have been" - meaning whatever it was it is infinitely better than the world right now with his presence. This "mob mentality" is proving itself to be not quite suitable anymore, and Leon clinging to the his long-gone mob role only serve to hinder his decision-making process. The core of his reasoning are that:


 * 1) Leon sees the world of his second life as just a reflection of the otome game he has experienced (and completed 100%) in the previous life; he does not see the world as another real life, where multiple possibilities and unknowable factors are not present in-game (i.e. Saintess Anne, Black Knight's back story, Lespinasse House' backstory,...). This fixates Leon that the world must run the course similarly to the game.
 * 2) Subconsciously, Leon sees the people in the otome game world as characters who are fulfilling the roles they are destined with; he does not treat them as truly independent entity with their own personalities and desires. This also extent to how Leon sees himself - "a background character with no role to play".

Heavily affected by the imposter syndrome, (namely feeling a sense of guilt for taking the AIs from the supposed "rightful owner" Olivia, overstepping his "mob" role, skewering the game's original plot,...) Leon 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 the two "untouchables" that he has genuine interest in. However, most of this backfires on him, resulting in him getting gradually distanced from his dream of a peaceful life.

Leon would also feel a sense of extreme guilt in the aftermath of the Fanoss invasion, as he watched the wreckage of hundreds of airships and armours floating around the water; he blamed himself for bearing such an important role in the "final event of the first game", causing so much casualties for being an incompetent "mob". This is a few time Leon's imposter syndrome merge with his disdain for loss of human lives, showing his out of touch and an utter inability to accept the new reality.

Seeing himself as just a fraud/an imposter/an anomaly in the world, Leon does not fully recognize how much of an influence he has towards others. This side of him is also shown when it comes to romance where he either inadvertently doesn't realise the affections of various girls he earns throughout the series or subconsciously aware but choose to live in active denial.

Balcus's Side of the Family
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, Balcus went out of his way to get Leon a ship and various other gear for Leon to survive his life adventuring for fortune, despite their household already in debt. Balcus was also quick to decapitate Miauler, when he found out about the servant's attempt to place false charges on Leon, which almost ended in his son's execution.
 * Balcus Fou Bartfort (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 Fou Bartfort (Mother)

They share a good brotherly relationship with each other, since Nicks was kind enough to risk his life by sending the information regarding the Forest Of Ladies to Leon, which Leon repaid in kind by paying Nicks' school fees and daily expenses, ensuring his brother would be able to study without taking part-time jobs, which Nicks is thankful for.
 * Nicks Fou Bartfort (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 as well as noble customs. 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 Fou Bartfort (Older Sister)

Finley and Leon does not share as much interactions, but it can assumed that Leon has a love-hate relationship with her too, but not to the extreme of Jenna's. Still, Leon stood out for her when she was bullied by some male freshmen of the Royal Academy.
 * Finley Fou Bartfort (Younger Sister)

*More information will be added soon later.*

Colin is amazed by Leon's fighting achievements. His admiration and respect for Leon is to the extent that he was willing to get over his heartbreak and apologise to his big bro.
 * Colin Fou Bartfort (Younger Brother)

*More information will be added soon later.*

Zola's Side of the Family (Former)
Leon does not like anyone on that side of the family, hate them as they keep disrespecting Leon's family side. Later the incident between Holfort Kingdom and Principality of Fanoss, Zola's family side are no longer part of Bartfort Household.
 * Zola
 * Rutart
 * Merce

Fiancées= 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, despite the fact that he was indirectly protecting the girl from bullies within the school. 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 trying his best to be faithful to her and Livia.
 * Angelica Rapha Redgrave

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.

*More information will be added soon later.*

Nobles= 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. This could be due to the fact that she was the closest type of ideal woman he was searching for in both his past and current life.
 * Mylene Rapha Holfort (Love Interest)

*More information will be added soon later.*

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.
 * Roland Rapha Holfort

Leon, on the other hand, realizes how Roland is involved in his promotions and unfavorable situations, which further deepens their dislike for one another. 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 interested in Leon.
 * Hertrude Sera Fanoss

Leon maintains a close yet professional relation with the Prime Minister. He was delighted when the Atlee House gifted the Schwert though felt pressured whenever Bernard brought up the subject of Clarice.
 * Bernard Fia Atlee (Ally)

*More information will be added soon later.*

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.

When Leon first noticed Marie in the academy, he felt a surge of fury "for some reason", but was unable to make sense of his emotions. During the first few weeks in the academy, Leon easily reads through her manipulation of the princes and realizes that she, like him, was reincarnated. 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 Lafan (Previous Life 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 Durland & Raymond Fou Arkin (Classmates/Groupmates)

Leon has kept his overall good relationship with both of them even though both became envious (though this jealousy is of no detriment to their close relations) of Leon's progress 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. When Leon needed help, they and other poor noble students rushed to his aid in the Commonwealth, rallied by Angelica.

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 Fou Roseblade (Senior)

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 (Senior)

One of Leon's classmates who shared a similar status in their nobility when he first enrolled. Lucle 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.
 * Lucle (Senior/Groupmate)

Leon highly respects his teacher, finding him as the perfect gentleman. They have an amicable relationship, with Leon frequently seeking for advices and wisdoms.
 * Master (Mentor)

*More information will be added soon later.*

The Prince's Entourage (Vassal)
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. Unbeknown to Leon, he was able to inspire and spark bravery for the entourage, in which some of them viewed Leon as the ideal & selfless man they could ever become. During their trip to Alzer, they gradually gained respect and some sort of comradeship with the second Bartfort son. After returning to their homeland, they were made to become Leon's protectorates/vassals. . 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 Rapha Holfort

Though not required to become Leon's vassal like the other four; Julius volunteered anyway, stating he has trust and respect for Leon, plus he would "get lonely" for being left out.

*More information will be added soon later.*

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

*More information will be added soon later.*

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

*More information will be added soon later.*

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

*More information will be added soon later.*

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 an air pirate.
 * Greg Fou Seberg

*More information will be added soon later.*

Others= Luxion is an old human AI that Leon obtained from its cheat item dungeon, in his attempts to avoid a marriage that was set up by Zola. 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 & Cleare (AI Servant)

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 Republic, 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.

Cleare is an old human AI that Leon gained loyalty from a ruin (actually old human's lab overran by elf). Though Cleare self-destruct, its data was uploaded to Luxion; later Cleare was reconstructed by Luxion to protect and communicate with Olivia and Angelica when Leon had parted from the two. Cleare appears kinder and subservient to Leon when it comes to his orders but is not above the methods on how it carries those orders.

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 (Servant)

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

Abilities & Equipment
Closely resembling a "jack-of-all-trades", Leon is fairly competent on all forms of combat, but he is nowhere near a "master-of-none". In terms of individual fields of expertise there are people better than him (For instance: Chris is likely superior in swordsmanship or Jilk is a better sharpshooter and Brad is more proficient in magic). But Leon make up by being a taskmaster that can improvise, adapt and overcome as many odd situations as possible.

Physical
Leon was trained by his father, as well as being a student of the Holfort's academy — going through standard adventurer training and working hard to appease to the girls. He was never stated to be particularly good with a blade, but even in a dispirited mental state he could stop Brad's surprise attack.
 * Swordsmanship

Being accustomed to physically-demanding labour since his childhood, Leon's body is very much well-built. After the acquisition of Luxion, Leon doesn't train as much as he could have anymore, it's pretty obvious he does give enough effort to stay in shape,, as an extinct of being a young adventurer.
 * Body

Leon has displayed applaudable efficiency in handling airbikes and armours. While he is not as skilled of an armour controller as the Black Knight; Leon showed extreme competence as he could pinpoint and abuse Arroganz's blind spot in the "unfair" duel against Pierre, proving he understands his equipment from the inside-out.
 * Skilled Pilot

All men in Bartfort Household appeared to have a natural knack in piloting despite not all of them are either talented airbikers or renowned armoured soldiers.

Magic
Having New Human genes, magic particle is a non-toxicant to Leon, thus he can utilise the mystic arts through self-teaching and attending lectures as a student of the Holfort's academy. Although his overall magic grade is not at all remarkable (according to Julius) due to his semi-lazy personality, Leon mastered some advanced incantations that he deemed useful/convenient.

When Leon takes aim with his signature shotgun, magic circles would materialise in front of the gun's muzzle (depending on formula, small magic circles could appear inside/atop the main one). Once the trigger is pulled, the shotgun shells would pass through (thus got enchanted by) magic, gaining blue-yellow tracers (akin to lightning enveloped in bright sunlight), the pellets would chase down the enemy until a hit is achieved.
 * Lightning Magic

The most prominent use of this spell was against Fanoss' horde of monsters summoned by the Magic Flute (spell conjured with a big help from Luxion) and the monster inside Alzer's dungeon (spell conjured solely by Leon).

Leon can greatly enhance his physical capabilities for a short amount of time with magic. A good example is when he used magic to take down several demi-human servants when Earl Offrey's daughter threatened Queen Mylene.
 * Body-strengthening Magic

Familiars

 * Luxion and Cleare.

Battle Gear

 * Arroganz - A battle armour created by Luxion specially for his master Leon. It is much larger than normal armors and has an overall black livery and possesses tremendous speed and power, carries a great number of tools and weapons on its back, plus storing drones and missile launchers.


 * Broad Katana - He had a custom-made katana forged by Luxion shortly after acquiring the AI.


 * Shotgun - Leon's favourite small arms fire. It has a short barrel and wooden stock. The shotgun seems to be semi-automatic given that it lacks a lever or a pump. Most common shells used against human is less-lethal rubber slugs while electrified buckshot are used against monsters.


 * Battlesuit - It has a black colour scheme with a good muscular defense mechanism. The joints is extremely flexible and can move according to the user's will.


 * Schwert - An airbike gave to Leon by the Atlee family and modified by Luxion. It later gets another refit, with a new appearance resembling an aircraft and has the ability to combine with Arroganz (by merging on the armour's back).

Ornaments

 * "War Fortune Charm(?)" - An in-game talisman item that increase physical attributes and enhance close-quarter combat ability, but in reality their effect currently unknown. Leon charm is specially-made (a prototype) and never appear in-game. Was activated during final fight against Black Knight (Effect wasn't seen).
 * Friendship Bracelet - A talisman made in Jean's hometown, woven in fine rope. It was given to Leon (right before his return to Holfort Kingdom) by Jean, the representative for all Alzer Academy's students, as a gesture of good fate and friendship.

Airships

 * Partner - A 700m-long stealth battleships hastily built and commissioned by Luxion (using its main body) to participate in operation Air Pirate Subjugation. It features a variety of multi-purpose artillery system with superb range and penetration compare to contemporary airships of the same size, as well as exceptionally strong physical armour plating and magical barriers. Partner alone was enough to stalemate the main bulk of Fanoss armada and its monsters for the majority of the battle. It was put out of commission for refit and repair after the Fanoss invasion.


 * Einhorn - Lead ship of the Einhorn-class airship, it was constructed by Luxion before the journey to Alzer Republic; these ships are significantly smaller (sitting at 200m) than the giant Partner and designed for small envoys. Armed with a limited but powerful assortment of anti-ship and anti-air cannons; it alone was able to take on a large portion of Alzer's combined fleet (the legendary airship force which was undefeated in defensive battle).


 * Licorne - Second ship of the Einhorn-class (with changes and upgrades) built in secret by Cleare using Einhorn's spare parts. The ship's bow spot a naval ram shaped like a horn, a signature trademark of the Einhorn-class. It has a dazzling white colour scheme and thick platinum-coloured armor plates; Leon remarked it is almost indistinguishable from Einhorn (aside completely different colour), so although its specification are unknown, it is assumed to have similar performances to the lead ship.

Trivia
