This character serves as the homeroom teacher for the Talented students at the isolated island school, an adult without supernatural abilities overseeing the class within the government-established training facility. His precise background remains unspecified.

He maintains a passive presence, demonstrating minimal involvement in student affairs or conflicts even as violence escalates and disappearances occur. This detachment stems from being uninformed about the government's true agenda to eliminate the Talented; his lack of awareness of the conspiracy renders him functionally irrelevant to the central conflicts and manipulative schemes on the island.

Throughout the narrative, he exhibits no substantial character development or altered behavior in response to unfolding events. He consistently fulfills a peripheral role, primarily highlighting the absence of legitimate adult supervision or institutional support for the students. No spin-offs, alternate media, or expanded materials provide additional depth regarding his motivations, origins, or subsequent fate beyond this established pattern of oblivious passivity.
