Synopsis
Oliver's feud with Richard Andrews comes to a head, and he and Nanao must face the aristocrat in a duel within the labyrinth. But other agendas are at work, and the duel turns more dangerous than any of them expected.

Summary
Katie is trying to make friends with the troll. Meanwhile, Oliver states he will accept the duel with Richard as he feels there is no way to avoid conflict with him.

Some of the students start to make fun of Katie for trying to speak with the troll. They openly mock Katie and tell her to go live with the troll in the cage. Oliver, Guy and Nanao had enough and engage the students and fight them. They beat them, but for their actions the three of them get send to the detention room. Katie apologizes to them, since they ended up here because he shouldn't defend herself, but Oliver states she is wrong and they are here because he couldn't control himself. Michela agrees with their actions, but states that now most of the first-year students are against them and Richard will likely take advantage of that, and warns Oliver that the duel tomorrow won't be a fair one.

The next day, two students lead Oliver and his friends into the labyrinth and to the duel location. They are surprised to see a big colosseum and a large crowd of students who came to watch. The two students tell them that those who will be participating to head to the dueling grounds, while the rest can take seats in the stands. Oliver and Nanao head towards the dueling grounds, but Richard tells them to stand back as there is an exhibition battle first. Richard and his partner then face two kobolds and Richard easily kills one of them. After the battle, Richard tells Oliver that there is no honor he can gain from defeating Oliver, since he is beneath him and instead they will take turns hunting kobolds, and whoever slays more is the winner. Oliver sees that Richard has experience with hunting kobolds, while Nanao have zero, but starts to think that if he loses, his relationship with Richard may be fixed.

The second kobold attempts to leave, but is forced to get back and fight. As its been defeated and people laugh at it, Nanao gets angry and yells at everyone that they look despicable since they are fighting someone who doesn't have the will to fight, and almost most of them stand in safe distance. The students get angry and start throwing bottles at Nanao. She turns to Oliver and tells him that they should leave as there is no worthy battle here. Some students stop Nanao from leaving, stating they will beat her if she attempts to leave, but Nanao prefers to fight them than the kobolds. The students that led Oliver here, go to release the next kobold, but instead of a kobold, a garuda shows up and starts attacking the students, easily defeating Richard's partner and proceeding to do quick work of other students. Seeing it, Richard is shocked that a garuda is there. Oliver states its a divine beast familiar and they are no match for it. Text appears above the garuda, which asks them on how it feels to be the prey.

Richard gets scared and starts running. Seeing that, the garuda goes after him and as its about to kill him, Nanao comes in and stops the attack. Nanao then engages the garuda. Meanwhile, Michela protects Katie, Pete and Guy from the kobolds. Eventually, Nanao is about to be hit by the garuda's attack, but Oliver uses a spell to push her away from the attack, saving her. the garuda then turns towards Oliver and manages to evade his next attack and cuts his stomach. Nanao again engages the garuda and Oliver uses the chance to hide and start healing his wound. Richard asks Oliver on how he is fighting and isn't afraid. Oliver reveals he is afraid, but Nanao likely isn't. She isn't ordinary person like him, which is why he have to help her and teach her how to be an ordinary person. As Oliver leaves to return to the fight, he tells Richard that Nanao wanted to see Richard fight.

Rejoining the fight, Oliver tells Nanao that he will create an opening for her to strike and kill the garuda. Soon the garuda attempts a wind attack which Oliver waited for and uses Tonitrus to hinder it, giving a chance for Nanao to strike. However, the garuda recovers too quickly and Oliver moves in to protect Nanao with his body. Just as Garuda was about to hit him, Richard hits it with Impetus, saving Oliver. Nanao then jumps to attack the garuda. She gets cut by it, but she manages to cut its head and kill it. Nanao and Oliver thank Richard. He states that he is ready to risk his life, but is afraid to fight. However he is more afraid of losing and being called an embarrassment for his clan. He wonders on how they can fight someone who is more powerful than them without any hesitation. Nanao states that samurai cannot chose their foe and once the fight starts they can only believe in their victory. Oliver thinks differently and states that there is no shame to run from a foe you can't defeat. However, Richard stood up and fought, while most students fled, and Oliver will never forget the courage and honor that Richard demonstrated today. Nanao calls Richard comrade-in-arms, which moves him and he cries as he leaves.
