Shinno Akikage

A mocking and ridiculing demon. A curse itself. His greatest desire is to defile, to guide people to the wrong path, the demonic and evil one. But most of his deeds are trivial for him; they are only to shorten his time. He is a proper demon, and tries to grant the wish of the one who summoned him as much as he can, sharing it himself.

Therefore, he is trying to grant the darkest desire of Sera Nobuaki, brother of Sera Mizuki—to defile her to the utmost degree for them to fall into the same Hell together.

As a demon, he does not need to weave his personal dreams to manipulate the world of the collective unconscious, as humans do.
