"Zecchō Sunzen" is a manga series that revolves around the life of a high school student named Sunzen Zecchō, who possesses an extraordinary ability to see and interact with supernatural entities. These entities, often malevolent, are invisible to ordinary people and cause disturbances in the human world. Sunzen’s unique gift stems from a tragic incident in his childhood, where he lost his family to a powerful supernatural force. This event left him with a deep-seated determination to protect others from similar fates.

The narrative begins with Sunzen transferring to a new high school, where he encounters a classmate named Aoi Hoshino. Aoi, unaware of the supernatural world, becomes a target of these entities due to her latent spiritual energy. Sunzen steps in to protect her, revealing his abilities and drawing her into his world.
