is Rin's "bad" friend and classmate. He addresses himself as "oresama": a rather arrogant version of "ore" (the masculine word for "I" in Japanese). Being the Don Juan of the class, he is envious of the girls' attraction to Rin and often mentions that he will take care of the girls that he doesn't choose. Itsuki and Mayumi often fight over comments made about Mayumi's bust size.
