A samurai manga centered on a boy named Zan. Zan's father was a legendary swordsman who wielded a sword without a blade (similar to the Sakabatou from Rurouni Kenshin). After Zan's father passed away, Zan has since desired to follow in his father's footsteps. The story begins with Zan transferring to a new high school during his second year. When provoked, Zan somehow becomes exceptionally strong and demonstrates incredible sword technique, enabling him to defeat his opponents.
