Tsukasa is a nice guy, but most of the time, his overconfidence takes over, as he is usually very loud, and self-centred. Whenever he isn't self-centred, and overconfident, though, he is very kind, and helpful. Meanwhile, Rui is a shy, kind guy, who always helps. He really loves to talk to people about their struggles, and always listens to people, as he enjoys helping people calm down. In short: Tsukasa is a loudmouth, who can be nice at times, and Rui is a kind guy, who loves helping people.
