Volume 2
Hertrude used her Magic Flute to get the monsters under her control to capture the cruise liner with the Academy's students on their school trip with the fleet. She declared war against the Holfort Kingdom giving the students one hour to decide whether to surrender or die fighting. She then sent an envoy with Garrett leading it and their commands were to take only the students from the families of baron rank or higher only. Angelica deciding to sacrifice herself to save the rest, let the envoy take her as the only hostage, with Leon and Olivia against it. Hertrude greets Angelica when they arrived at the main ship, telling her that having her as the hostage will be enough and as they do not the others they can die.

After one hour had passed, Hertrude went to the see how the students were choosing to die and beckoned Angelica to watch. But seeing the liner moving in a collision course she was shocked and immediately asked for the Magic Flute, Angelica realizing that the flute was their secret weapon. Tears formed in Angelica's eyes when she saw Leon leading the charge against them in Schwert declaring that the students will prevail and the one leading them, Leon was one of the finest knights the Kingdom has ever got.

Garrett came to report that the monster their ship was on had eaten Leon. Angelica was terror stricken and glared at him, but to her relief Leon came through bursting through the monster was able to rescue and also take the Magic Flute and Hertrude as a hostage. They quickly retreated declaring to the soldiers of the Principality to drop their weapons as he had taken their princess as hostage with Angelica feeling grateful to Leon who had come to rescue him. He quickly went to the cruise liner and let Hertrude and Angelica down, but to everyone's dismay Garrett had ordered all the ships to open fire with Hertrude using a spell to release the monsters out of her control so the monsters would attacked the one who was controlling, so the monsters began moving towards the liner as well. Angelica seeing this was asking her why she was going to such desperate lengths. Seeing this Leon went out again to buy some time for them with Chris and the others helping as well. After some time Partner came to their rescue and started firing at the enemy ships and monsters. When Arroganz arrived on the liner, Hertrude asked if it was a Lost Item and finally remembered hearing about a knight who became quite famous for his exploits as an adventurer and that adventurer was Leon. Angelica and Oliva then took her to a room in Partner after they evacuated, to keep her safe in case somebody attacks amidst the chaos and also to keep an eye on her. Hertrude on seeing the black armors was shocked as Vandel was told not to sortie with Angelica being shocked as she could not believe that the Black Knight was here. With Olivia being clueless about him, Angelica explained about him to Olivia with her asking if Leon would be able to defeat such a strong opponent with Hertrude declaring that Vandel was their strongest knight and he was not someone who would lose to Leon. Leon had quite a hard fight against the Black Knight and the squadron he was leading but Leon was still able to win against them without killing anyone. Luxion destroyed the last remaining monsters who were gathering with them being able to thwart the invasion.

After the invasion, Marquess's faction decided to let Hertrude study abroad in the kingdom, so she will see the strength of their country and in the process will also try to curry favor towards the princess and the principality.

While Hertrude dislikes Leon for defeating her forces and capturing her, she also understands that he could be a very useful ally, and has, on several occasions, tried to get him to join the Principality but was dismissed by him. This is despite Luxion implying her motives were less selfish than Leon believed in the later stages and that she genuinely wished to recruit him out of a growing sense of attachment and or loneliness.
