Shiki is the lead vocalist of his high school's music club that later forms into a five-men idol band. He is a very energetic boy who loves to sing and loves his high school buddies, so rather than going their separate ways after graduation, Shiki intends to mastermind their debut as an idol unit. He also tends to add "honkii" or "mega" to any descriptor he uses, and ends all of his sentences with す（ssu). He's not the best at academics, so he studies with his buddies a few days before exams.
