After learning martial arts in the mountains for 17 years under his father's teachings, Yoichi Karasuma's father orders Yoichi to learn martial arts with the Ikaruga family in the city, as he has nothing left to teach him. The current head of the Ukiha Divine Wind Style Swordplay School of martial arts, Ibuki Ikaruga and her siblings gradually accept Yoichi as a freeloader at their dojo. In addition to domestic problems, Yoichi deals with Washizu's jealousy of Ibuki and Yoichi's supposed relationship and his school life. (from Wiki)
