Berkia (ベルキア Berukia) is one of Tsubaki's subclass and also one of his best friends.
Berkia 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. Berkia 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.
Not much is known about his past so far. It's revealed, he had a fight, where All of Love has cut off a large portion of his ponytail hair because he had the feeling he was even more beautiful than him.
Berkia is extremely over the top when it comes to personality. In chapter one, we see him acting like a street performer or a magician. He is very vain, thrives off attention, and does not like to be ignored. He is shown to comically overreact to most everything. As one of his subclass, Berkia is very loyal to Tsubaki. He likes to tease Sakuya along with Tsubaki.
