Fantasista SQUAD is a group made by four male teenagers that have came together to perform singing backstreet. Rui Kamishiro is the leader of the group, as he is the one who brought everyone together. Tsukasa Tenma is Rui's best friend, and helps him out a lot. Akito Shinonome and Toya Aoyagi got dragged in afterwards, but later on they showed to respect the group and come together every now and then. The four of them have very different personalities, but they get along pretty well.
