Ryuuto Kashima is a normal high school student who considers himself a "gloomy guy" and can be quite self-deprecating oftentimes. Despite this, he has friends that he cares a lot for to the point of just going along with their silly antics. He can be serious, at times, as well, especially when he shows interest in certain things. Ryuuto is a dedicated guy who keeps his word and feels guilty when he fails to do so.
