So yeah, the pills did kill Yuu, but only briefly. In a post-death, pre-afterlife scene involving Ashuramaru, an unseen angel, and a trumpet, he comes back imbued with even more of the demon’s power. He goes after Crowley straight away, and the vamp is impressed with his power, wondering if you can even still call him human.
Crowley isn’t worried, though; Yuu is, at the end of the day, only livestock. No matter how much he fights, he can’t win. Especially when Yuu’s friends end his fight by using Kiseki-o’s coffin to contain him so they can take him away. Guren, meanwhile, remains captive, but alive, and told Yuu he has “his own plan for himself.”
Shinoa and Guren’s squads meet back up with Narumi’s and head to the next rendezvous, but their way is blocked by a single enemy: Mika. As soon as he spots an unconscious Yuu in their clutches, it just gets Yuu even more upset. He’s taking Yuu away from those human bastards. And he does it in a very Yuu-like fashion: rushing forward on a wing and a prayer.
He meets stiff from Guren’s elites and the grunts, but he will not be denied his family. When Yuu’s friends try to convince him they’re also Yuu’s family, he won’t listen. It’s just him and Yuu. No other friends, no other family, nothing else to live for. But his opinion on Yuu’s “captors” might just change a tiny bit when Shinoa, Mitsu, Yoichi and Shiho turn their weapons onto their own allies in order to protect him and Yuu.
Needless to say, Yuu’s fam is in big, big trouble, but the recriminations have to wait, as vampire reinforcements arrive. Mika, in bad shape, makes off with Yuu, and Shinoa trusts they’ll meet again at the airport. Then the vamps advance, Yayoi and Kagiyama are killed in quick succession, and even more vamps descend. Shinya orders Shinoa and the others spared for the time being so they can help fight off the enemy and retreat.
Will Mika hold to Shinoa’s plan to meet back up? How will Shinya and Narumi deal with their insubordinate subordinates, assuming they survive the vampire onslaught? And how will Yuu react when he wakes up, and in place of his squad, he’s now with Mika? Both brothers have sought to “save” one another from their respective plights; now they’re in the same boat together.
