Sachiko's father and Yoshie's husband. In their house, which both Naomi and Ayumi go investigating, every male name from Shinozaki's family is crossed out in the family tree but his. There is also a photo of him in his house, but his face is covered in scribbles. Due to an unconfirmed circumstance or strange occurrence, the Shinozaki family only produces female heirs. The Shinozaki Family adopts male heirs thus the heirs inheriting the Shinozaki surname, but this also comes with each and every male dying a few years after the birth of the child. Seiji's fate was no different as referenced by a brief scene within the Shinozaki estate.
