‘Now then, it's time to see what kind of a story is waiting for us.’ -Kamishiro Rui

Kamishiro Rui is a third-year student at Kamiyama High School. He is a member of the musical show unit Wonderlands x Showtime.

Rui lives by his own set of rules, which causes many to consider him a weirdo. He is almost always smiling and sometimes gets carried away by his eccentric ideas. Despite the apparent riskiness of his ideas, Rui does his best to take safety into consideration.
