She asks him if he is afraid of her and he answers that it's the case but that they are now part of the same team.

Kyou Rei tells him not to look down on her, that he doesn't know anything, and makes him want to kill them all. He is pitifully weak and doesn't deserve to live. She plunges slowly her blade in his neck but stops when she heard the other members looking for him.
