Depending on whether Akiha dies in her fight with SHIKI, there are two endings. In both, Kohaku reveals that she was the cause of everything, by manipulating SHIKI into killing Makihisa, and then into a violent confrontation with Akiha, as a means to kill the Tohno family and get revenge for years of abuse. If Akiha dies, Kohaku stabs herself afterwards, unable to live any longer without purpose. If Akiha lives, Kohaku ingests poison, whose concept is killed by Shiki, saving her. She wakes up without her memory and is given the name, "Nanaya," returning as a peaceful maid to the Tohno Mansion.
