Samurai Harem

After seventeen years of rigorous samurai training under his father, Yoichi is stunned when his father declares he has nothing left to teach him. Instead, he arranges for Yoichi to continue his studies at a dojo run by an old friend. Forced to leave his peaceful mountain village behind, Yoichi moves to the city to live with his father's friend and family. Adjusting to urban life is difficult enough, but his new home comes with another challenge: four sisters, all beautiful, and a training regimen far harsher than anything he has ever faced.
