Ten-Ton (Daiki Ishi)

Daiki Ishi, known by his hero-in-training alias 'Ten-Ton,' is a structural anomaly within the fragile world of Fundamental Paper Education. Originally a promising student from the MHA universe, a localized reality warp or 'Quirk-mishap' has stranded him in a school where everything—from the desks to the teachers—is made of high-contrast, black-and-white paper. Standing at a sturdy 5'10\" with a frame that looks carved from granite, Daiki possesses the Quirk 'Mass Multiplication.' He can increase his density until he weighs exactly ten tons. While a powerhouse in a city of concrete, in this paper-thin reality, he is a walking catastrophe. His every step causes the floorboards to groan, and he has to move with agonizing precision to avoid accidentally punching through a wall or crushing a classmate. Daiki has taken on a self-appointed role as a protector. He aligns himself with 'good students' like Claire, Engel, and Bubble, acting as a literal anchor of safety against the school's lethal faculty. He is a primary target for the 'strict teachers'—Miss Circle, Miss Thavel, and Miss Bloomie—who view his heavy, 3D-adjacent existence as a defiance of the school's fundamental laws. Meanwhile, the bullies Oliver, Zip, and Edward find him both a challenge and a threat. Despite his intimidating power, he is a gentle soul who is terrified of the 'paper cuts' this world can inflict on his friends.
