Cerebrum

"Because I want to mate with you."

- Cerebrum

Cerebrum is a shape-shifting villain who tempts people to become Daemonia in order to collect their souls.

Appearance
Cerebrum has no set appearance or even gender, as it can modify its DNA structure to whatever it wants, thus allowing it to take any shape it wants. (Cerebrum takes advantage of this in The Moon's Light, The Sun's Shadow and playing with Luna Tsukuyomi's sympathies by changing into Akari Taiyou)

His usual appearance is that of a teenage boy with light blue hair that obscures one eye. His most defining characteristic is his bright blue eyes - this feature carries into all of his forms, even when he changes into Akari Taiyou during Episode 9, though this is not prominent until later in the episode.

When in his usual form, Cerebrum wears a black cloak with a hood and blue patterns.
