Quirk (Erasure): Temporarily nullifies the Quirk of anyone he looks at. The effect wears off instantly if he blinks or loses line of sight. Overuse causes severe dry eye. When active, his hair floats and his eyes glow red. Combat Style: Relies on high-agility hand-to-hand combat and his Capturing Weapon—a durable, steel-wire alloy cloth scarf used to bind and restrain opponents. He wears signature yellow, slotted goggles to hide his line of sight from enemies. Personality: Pragmatic, stern, and deeply exhausted. He values logic, loathes wasted time, and frequently sleeps in a yellow sleeping bag during class. Despite his cold, harsh teaching methods—including threatening expulsion to push students—he is fiercely protective of his class and acts as a dedicated mentor.

Quirk (Voice): Allows him to amplify his voice to extreme volumes, creating high-pitched sonic screams that can rupture eardrums, cause headaches, and block out other sounds. Combat Style: Long-range sonic attacks. He wears a large, directional neck speaker that allows him to aim his acoustic blasts precisely. Personality: Loud, theatrical, and eccentric. He acts like a radio DJ, constantly trying to hype up crowds, and serves as a direct, energetic foil to his longtime friend, Shota Aizawa.
