This story by Yuu Minamoto will be shipped in its last and 15th volume in March.
A great harem series with battle and comedy elements, it started in 2006 in Shonen Champion magazine, as it tells the story of a young man who learns martial arts in a dojo with four sisters.
The anime was released by Section23 studios in North America last year.
This is the official description:
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 hes going to study some new martial arts techniques but what hes really going to learn about are some slightly more practical things, like electrical appliances, modern clothing and, most especially, how NOT to make girls to 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 dont really seem to understand how proper girls are supposed to behave! Will Yoichis 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?
It's also known as Asu no Yoishi!
