相坂 文樹

Fumiki is a second year student of Yuujin Academy (湧仁学園). Bored of his life of no purpose, Fumiki decides to find a "stimulus" to change his life. Since he loves writing novel, he decides to take a look on literature club. Although, after hearing Uni's speech, he changes his mind and joins Electronic Art Club (電芸部) instead.

He has a strong ability to fantasize. For that reason, he is approached by a sepheric Erediyu and forced to make a contract with her to gather DD to make her wish come true. But later, another sepheric confronts him and tells him that he is being deceived by Erediyu and he should cooperate with her instead to stop Erediyu's evil plan. Despite being reluctant at first, he decides to just go along with it since it makes him feel like a protagonist of some sort.
