Itsuki Midoriba 緑葉樹

Itsuki Midoriba is Rin's "bad" friend and classmate. 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, but this is just a cover for his secret love for her.
