Kuraki Fuzuchi possesses extraordinary psychic abilities and sword fighting prowess, yet he remains a reserved and unassuming individual. It is during a rare festival, held once every 49 years at a remote shrine in the mountains, that Kuraki meets Takeo Nanachi - a college student whose dormant supernatural powers are akin to Kuraki's. As fate would have it, Nanachi has come to purify his late grandfather's sword, and their chance encounter leads Nanachi to witness Kuraki's induction into the ranks of a Shaman. Thus begins a journey where their lives become entwined, encountering various otherworldly beings possessing both good and evil intent, while also delving into a parallel backstory of their past lives. As part of this elusive and captivating tale, Volume 7 brings forth an extra episode entitled "Hidari no Kei".
