Belkia is one of Tsubaki's subclass and also one of his best friends. Belkia is rather eccentric with his appearance. He has long pink hair tied back in a ponytail with matching glasses. He wears a white suit with a white top hat as well. He wears a black band around his neck, like many of Tsubaki's subclass do. Belkia is capable of turning into a doll version of himself in a way similar to how the servamps transform into animals and, like the servamps, he is still capable of talking while in this form.
