Yuusuke is a bubbly and cheerful person, who is popular with the girls and generally well-liked. Much to Shin's chagrin, Yuusuke always has an idiotic grin pasted on his face. Initially, he develops a liking for Maria as she is beautiful and has an intriguing personality. He is the first student to approach her and constantly pops up wherever she is. While he is extremely fond of her, it is not yet revealed if it is more than admiration. It seems as if he knows that Meguro likes Maria, because in chapter 11 he calls Meguro out and tells him that if he doesn't step up he might "steal Maria away". Yuusuke taught Maria the "lovely transform". He calls Shin "Megu-chin" and Maria, "Maria-chi". His face forms a comical style with thick dark outlined eyes and a w-shaped smiled when someone (mainly Kawai) is blatantly against one of his ideas. He also confessed his love to Maria later in the series.
