Blanc
Neptune
Noire
Anonydeath is obsessed with teasing Noire, doing anything to embarrass her, such as planting cameras in her room and taking pictures of her. He keeps the photos for himself, since they are only for him to look at. He has no ill will towards her; while he does fight her on several occasions, he only does so in self-defense. While he enjoys teasing her, he does repay his debt to her and the other CPUs when they save him.
Plutia
Peashy
Anonydeath calls Peashy his daughter, despite the fact that they are not relatives. Even when Peashy regains her memory, she still refers him as her father.

Copypaste
Mister Badd
Rei Ryghts
Anonydeath has nothing special with Rei, though he does defend her from time to time when the other members yell at her.
