Seiji Morifumi's Links
Harusuke's uncle. Has no idea they exist.
Seiji's nephew. Has no idea they exist.
Emi's little brother. Though she does provide most of his specimens, they cannot stand how loud she is. He puts up with it anyways as long as she doesnt come into his darkroom unannounced. AGAIN.
Seiji's big sister. She is often the one to provide Seiji with corpses for autopsy and disposal. She loves her babiest brother and teases him often.
Gorou's younger sibling. They dont interact much, but by Seiji's standards Gorou is the least annoying of their siblings. Maybe partially because their late-night chats helped Seiji get the bravery to get together with Damien.
Seiji's older sibling. They're both a bit quiet, but when they do talk together its always a pleasant and useful conversation.
