SHIKI reveals himself to Akiha, wanting to take her back as his sister and kill Shiki for taking her away and living the life that was his. Akiha uses the powers of the Tohno to fight him off, which puts considerable strain on her. She tells Shiki that she may Invert if she overexerts herself, and that most of her power goes into keeping Shiki alive, to compensate for the connection between SHIKI and Shiki. She tells him that his true family was the Nanaya clan, who Makihisa had exterminated years before.
