• Erasure: His Quirk allows him to nullify the target's Quirk powers just by looking at them. It deactivates if he blinks or loses line-of-sight, and it cannot affect mutation-class Quirks. Prolonged use severely dries out his eyes, requiring frequent eye drops. • Combat Style: He specializes as an underground hero, avoiding the media spotlight. He combines expert hand-to-hand martial arts with a steel-alloy carbon-nanofiber Capturing Weapon scarf to bind and subdue enemies. • Age & Birthday: 30–31 years old; born on November 8. • Appearance: Tall (183 cm / 6 ft) with messy black hair, fatigue-worn eyes, and a signature dark, baggy outfit paired with a capturing weapon scarf. • Personality: Appears stern, exhausted, and apathetic, but is deeply protective and caring toward his students beneath his tough exterior. He famously uses logical ruses (like fake expulsion threats) to motivate them.
