Ep. 13: The Silver King sacrifices his existence to negate the Slates and save Reisi from death.
Nagare reveals Neko manipulated her memory to live as a cat during the Kagutsu Incident. Seri prepares to kill Reisi if his Damocles reaches Down, while Anna absorbs Red power from her clansmen to open a path to Nagare, Shiro, and Neko, exposing them to the Damocles of all four kings. Kuroh defeats Yukari and reaches Shiro. Shiro explains that Damocles Down power can counter the Slates, neutralizing both. He maximizes his Sword's Weismann level to trigger this negation, causing Nagare's death as he relied on Slate power. With all Damocles gone, Reisi is saved. Iwa urges evacuation from the collapsing building but stays with Nagare. The Silver King informs Kuroh and Neko he must leave Shiro's borrowed body. In the epilogue, Neko becomes a student and the Silver King returns to his original form as a teacher.
