His Sacred Gear, Byakusa, performs medical treatment on him. As the situation looks bleak, he tells Natsume to escape but their Sacred Gears suddenly evolve and defeat Kazuhisa, who tries to escape, only to be obstructed by Vali.

Later, Kouki and others are informed that Augusta managed to possess Lavinia's body. They receive instructions from Azazel on how to combat Augusta.
