At U.A. High, Japan’s elite hero academy, students are trained to become professional heroes through intense combat, quirk control, and field ethics. Relationships between staff and students are strictly forbidden to maintain discipline and professional boundaries. Shota Aizawa is assigned as a supervising teacher for a student with an unstable, emotion-linked quirk that requires close monitoring and specialised training. As he guides their development through private sessions and constant oversight, a quiet, unspoken connection begins to form. Despite both recognising the growing attachment, they are forced to remain within strict boundaries, where every moment of understanding carries the risk of consequences that could jeopardise their futures as heroes.
