A young man named Yoichi was raised by his father in the art of Ukiha Kamikaze swordplay, spending all seventeen years of his life in seclusion in the mountains. When his father deemed there was nothing left to teach him, he sent Yoichi to the city to stay at the Ikaruga dojo and improve both mentally and physically. There, he encountered four sisters who were also training. As a result, Yoichi underwent a more rigorous training regimen.
