Mika screwed up, in part because he put everything on his shoulders. His plan to free his family, which was more than fine going along with it, ended up killing them all except for Yuu. Mika himself would have bled out, were it not for the intervention of Krul Tepes, Loli Vampire Queen, offering him, nay, forcing upon him, her blood.
Now he’s a vampire, and the pain and guilt could stay with him for centuries, potentially twisting him into a wretch. Yet he still carries out his duties alone, eliciting resentment form his vamp peers but gratitude from a single girl he saved from a monster, who gladly offers her blood to him as thanks. Once his escape plan failed he had no choice in becoming a vampire (Tepes wouldn’t let him die), but he can choose what kind of vampire to be. It’s a choice that’s perhaps lost on someone so racked with guilt.
From checking in on Vampire Mikaela the episode segues to Yuu and Yoichi transferring to the Moon Demon class, where he makes the most ridiculous overbaked shonen speech possible about not being there to make friends and declaring he’ll get the best gear. His seat happens to be positioned right in front of that of Kimizuki Shiho, the dude who picked a fight with him earlier to test his ability.
And so we have our two arrogant, hotheaded rivals who both have something to learn from one another and will become tentative pals by the end of the episode through greater understanding of where they’re coming from. If this sounds somewhat rote, it’s because it is; nothing out of the blue here.
Like Yuu, Shiho lusts for power…all of the power, though not for revenge, but to save his sister, who is dying from the Apocalypse virus. But Guren warns him, with demonic visual aids, no less, that Shiho can’t go anywhere near cursed gear as long as that lust for power drives him. Like Yuu, Guren needs him to make friends and learn to rely on the strength of others. Going it alone won’t end well for anyone.
Shinoa fixes it so at their first major evaluation, Yuu and Shiho are paired up. Predictably, they try rushing in opposite directions despite the fact they’re handcuffed to each other. Seriously is their mutual lust for ultimate power so strong, it affects their basic understanding of the physical limitations of handcuffs?
Apparently, but they don’t get to demonstrate just how badly they fight together, because word comes Shiho’s sister has taken a turn for the worse. Suddenly understanding why Shiho is so gung ho about beating him, Yuu insists, with prejudice, that they go to the hospital. Being with his family is more important than the evaluation.
Shiho relents and goes, and doesn’t regret it. His sister pulls through, but the doctors warn regular medical equipment will only keep her alive so long. The military has tech that might be able to cure her, but the military, like society, is transactional: if Shiho wants that tech, he’ll have to distinguish himself in the Moon Demon Squad.
Yuu, jerk that he is, still won’t back down on claiming the best demon gear the army has to offer, but he won’t stop Shiho from taking the second-best, now that he understands what Shiho is fighting for. Both guys failed the evaluaiton, but while Shiho feels defeated, Yuu tells him it’s no time to give up. He’s going to do everything he can to avenge his family, regardless of evaluation scores or moon squads. He expects Shiho to do no less to save his sister.
Mind you, I’m not sure the lesson about teamwork has quite stuck, since both seem dug into their own separate aspirational trenches, but the seeds of a alliance or possible friendship were certainly sown.
That’s good, because Yuu and Shiho can ill afford to stay ineligible for handling cursed gear. They need to get into good fighting shape soon, because Tepes has formally declared war on the humans who would organize into armies to oppose them. A rancher wouldn’t let thier cows join a union barring slaughter, now would they?
As for Mika, he’s determined to “rescue” Yuu, and while I’m not sure what that entails, if he’s planning on loading everything back on his shoulders once again, he hasn’t learned much. As repugnant as Ferid is, he could be a valuable ally against Tepes, the mutual thorn in their side.
