Add a short synopsis here.
Ayumu recieves a visit from a talking, bipedal doberman who seems to think Ayumu's very existence is out of order. However, upon learning that he was resurrected by Yuu, the dog decides to leave him alone and instead collect the souls of people who were recently stabbed by the serial killer. Ayumu thinks it could be the same person who killed him, and he decides to follow the dog.
The dog then tells Ayumu that Yuu chose him to receive a special gift for some reason, and to protect Yuu as both Ayumu and the dog are stabbed by the sword of the same serial killer.
Ayumu later wakes up at his house, and Yuu reveals part of her story to him: She is a powerful necromancer, to the point where she puts on plate armor and speaks only through writing on a notepad because if she said any words or took off the armor she might accidentally unleash havoc upon the world with her powerful magic. Ayumu accepts her explanation as she starts crying.
The next day, Ayumu and his friends find themselves trying to kill a high-class Megalo in the form of a large, floating humpback whale wearing a suit. Ayumu manages to slaughter the whale with Seraphim and Haruna's help.
However, at the very end, the scene shifts to the hospital from the last episode. A blade is shown falling to the floor as Kyoko appears to be no more than a bloody corpse.
