After Nrvnqsr's murder, in the Arcueid route, Shiki discovers that Akiha is not his real sister and that his past as the former heir of Tohno family was made up by his "father", Makihisa Tohno via hypnotism, whose powers the Tohno family had due to a weak demonic lineage. He was adopted in the Tohno family when he was little because he had the same name as the real family heir SHIKI Tohno. However, when SHIKI and Shiki were nine years old, SHIKI murders Shiki in a fit of madness. Makihisa kills SHIKI, thinking that the demonic blood had made him insane, but could not finish the job as he was still his child.
