Toshiya Dairenji (大連寺 利矢 Dairenji Toshiya?) is Suzuka's older brother, he died several years prior to the story due to their father's experimentation. In order to bring him back, she attempted the Taizan Fukun Ritual, only for him to try and kill her due to the ritual requiring a human sacrifice. The ritual was interrupted and he returned to being a corpse, later put to rest.
The magical investigators ruled that the ritual had merely invited a wandering spirit into his body, rather than truly resurrecting him.
