Template:Character Friday (フライデー; Furaidē) is a youth type of corpse who accompanies Watson as registrar.
Friday is very skinny and pale, his eyes are blue/purple, his hair gray and he mostly wears a white shirt along with black pants. His look is mostly blank and emotionless.
Being a living corpse, Friday is kind of emotionless and soulless. He obeys whatever Watson says and does not speak. However, when Watson found the Notes, Friday's soul was being brought back to him, he whined and screamed, trying to speak. When he loses control he attacks Watson and tries eating any human in the way.
