Takaya doesn't remember being a warlord, which means Naoe gets to love him without the weight of who he was. The show builds its entire emotional architecture on that single fact, then watches it collapse the moment Takaya starts remembering anyway. Spirit battles and faction politics are window dressing for a story about two people realizing they're trapped in a cycle they can't break.

Takaya Ohgi seems like an ordinary high school student with one simple goal: protect his best friend and keep living a normal life. That changes when an older man named Naoe appears and tells him he is the reincarnation of Lord Kagetora. Naoe, a possessor himself, awakens Takaya's power to exorcise evil spirits so he can fight the Feudal Underworld. Most possessors recall their earlier lives, but Takaya remembers nothing, and Naoe is grateful for that, given the passionate and abusive past he shared with Kagetora. As Takaya's abilities grow, memories surface of what Naoe did out of love for him. Meanwhile the Hojo and Fuma clans launch their attack as the Feudal Underworld spills into the living world.
