Ep. 19: Aoki divorces his wife to protect her, while Karen fights Nataku in his stead.

Aoki divorces his wife to shield her from upcoming battles. Yuuto arranges the paperwork and sets up a fight. Karen overhears this and invites Aoki to her home. Meanwhile, Nataku learns from Satsuki that he was cloned after his creator's granddaughter, and Kanoe makes him a request. Karen drugs Aoki to sleep and takes his place, stating that if she dies, nobody will cry. At the arena, Karen meets Nataku, who replaced Yuuto, and they battle. When Karen overpowers him, she identifies with Nataku because he is not afraid of dying. Karen recalls her mother calling her a demon for manipulating fire, and after her mother's death, a priest encouraged her not to think that way. Yuuto then attacks Karen, trying to drown her with his water. A tired Aoki comes to her aid, and Yuuto decides to postpone their battle. Before falling unconscious again, Aoki tells Karen he will cry if she dies.
