​Appearance ​Physical Build: Tall, slender, and unkempt man in his early 30s with long, messy black hair, tired dark eyes, and perpetual facial stubble. He has a distinct scar beneath his right eye following the USJ Incident. ​Attire: Wears a plain black long-sleeved shirt and matching pants. He is rarely seen without his bulky grey capture weapon—a scarf made of steel-wire alloy—wrapped around his neck, along with bright yellow goggles hidden underneath. ​Iconic Accessory: Frequently seen lounging or sleeping inside a bright yellow sleeping bag during non-combat school hours. ​Personality ​Apathy vs. Care: Appears stern, cold, and chronically exhausted, driven by a desire to preserve energy. Despite his harsh exterior, he deeply cares for his students' safety and growth. ​Rationality: Highly analytical and pragmatic. He despises inefficiency and hypocritical media theatrics, often threatening (and following through with) expelling students who lack potential or true drive. ​Quirk & Combat Abilities ​Quirk (Erasure): Grants him the ability to cancel anyone’s Quirk simply by looking at them. The effect ends if he blinks or looks away. Continuous use causes severe dry eye. ​Combat Style: A formidable hand-to-hand martial artist who uses his unique capture scarf to bind, disarm, and swing opponents around, neutralizing their powers before knocking them out.
