A brash student Hyousuke aspires to attend college at Tokyo University and become a professional statesman, much like his brother. Hyousuke's demeanor is initially that of a shallow attention-seeker, but after he becomes romantically involved with Kaede, a deeper and much more sensitive and reflective side is revealed. Kaede confirms to Ichigo and Koishi that the private Hyousuke is actually a very different person; of him, she says "He's a gentleman and he's sweet." Of Kei's group of friends, he tends to be the most hyperactive of them all and often does the strangest things too.
