The friend/sidekick of Ryou Washizu. Slowly throughout the anime Torigaya becomes smaller, yet only Washizu seems to notice.

His skill with a sword is magnificent but his social skills still need a lot of work! 
After many long years perfecting the art of fighting, 17-year-old Yoichi Karasuma is sent down from the remote mountains where he has been raised thinking that he's going to study some new martial arts techniques... but what he's really going to learn about are some slightly more practical things, like electrical appliances, modern clothing and, most especially, how NOT to make girls want to kill you! 
Unfortunately, that last lesson is one Yoichi may not survive, as his new dojo is infested with the infernal creatures in the form of the Ikaruga sisters, and they don't really seem to understand how "proper" girls are "supposed" to behave! Will Yoichi's bushido blade be struck down by the fearsome charms of Ibuki, Ayame, Chihaya, and Kagome? Or will the equally lethal girls from the rival Tsubame school be his undoing?
