Acca

Acca is a mannequin with black glasses and a very slight smile. His build appears to be that of an average male, although it can be hard to tell since he is covered foot to neck.
Although his true motives are quite unclear for now, his purpose is to guide the four main protagonists to battle in the Egg World as Ura-Acca does.
Acca, along with Ura Acca, is one of the founders of Japan Plati. Originally regular humans, both of them abandoned their bodies and uploaded their brains into the bodies of mannequins that only exist in the Egg World.

Abilities :
He is capable of making his voice heard by the protagonists from anywhere or anything, or interact with non living objects, in the Egg World and in the reality. For example, in episode 5 and episode 6, he uses speakers or bins. Ura-Acca possesses the same ability. They can also communicate through the pomanders. Both Acca and Ura-Acca can observe what the protagonists are doing, even in their dreams, through a big screen which shows directly what's happening. They almost always have an eye on them.
