Blue Exorcist: Kyoto Saga

Rin must tame his infernal power while hunting a traitor who’s stealing the very eyes of a demon king.

When the Impure King’s left eye vanishes from True Cross Academy’s Deep Keep, the Ex-Wire squad is thrust into a frantic hunt across Kyoto. Rin Okumura, the half‑demon son of Satan, must set aside the scandal of his lineage and join his classmates in tracking down the stolen relics before the academy’s defenses crumble. Their quest leads them into the shadowy corridors of ancient shrines and the bustling streets of Kyoto, where a second theft threatens to unleash the full fury of the Impure King. Amid the chase, Rin feels the growing chasm between himself and his comrades. Determined to prove he’s more than his cursed blood, he throws himself into grueling training to master his demonic flames without losing control. As the right eye disappears and suspicion of a traitor spreads like wildfire, the team is forced to rely on every ounce of their combined strength and resolve. The arc blends high‑octane battles with uneasy alliances, pushing the young exorcists to confront both external demons and the darkness lurking within their own ranks.

This shounen action series follows teen exorcists battling a plague demon in Kyoto, featuring fantasy violence and some graphic body horror from rotting flesh and disease. The story explores betrayal and a protagonist struggling with his demonic heritage, with mild language and very limited sexual content.
