Hizashi Yamada, alias Present Mic, balances dual roles as an English instructor at U.A. High School and a Pro Hero with a vibrant radio-host flair. His "Voice" Quirk, active since birth when his first cry ruptured bystanders’ eardrums, generates amplified sound waves for combat techniques like Loud Voice, DJ Punch, and Loud-Out Shout. A directional speaker collar channels these sonic bursts, preventing uncontrolled collateral damage. Physically striking at 185 cm, he sports spiked blond hair, rectangular greenish-yellow eyes shielded by orange sunglasses, and a hero costume blending black leather, studded accents, and "HAGE"-branded headphones. Off-duty, his casual ensembles pair tied-back hair with bold jewelry. Post-Final War, his lengthened locks and rounded glasses mark subtle shifts in appearance. A theatrical persona defines him—addressing crowds as "listeners," helming the "Put Your Hands Up Radio" show, and emceeing school spectacles. Yet beneath the exuberance lies tactical shrewdness: he prioritizes student welfare, deduces covert threats like U.A.’s traitor, and harbors entomophobia exploited when opponents weaponized insects during final exams. Born July 7, he formed formative bonds at U.A. with classmates Shota Aizawa and Oboro Shirakumo. Shirakumo’s mission-related death—later compounded by his corpse’s transformation into Nomu Kurogiri—sparked divergent coping mechanisms: Aizawa retreated inward, while Yamada masked grief with hyperactive workaholism. Their enduring 14-year friendship includes Yamada coining Aizawa’s hero moniker, "Eraser Head." Key engagements span announcing entrance exams, countering the U.S.J. assault, and confronting Dr. Kyudai Garaki over Kurogiri’s creation—a clash where Yamada’s rare fury surfaced as he denounced Shirakumo’s desecration. The *Vigilantes* spin-off further unpacks his youth, camaraderie, and unresolved trauma. Supplementary notes list blood type B, an urbanite’s disdain for silence, hero stats favoring intellect and teamwork, casual tastes for fried chicken and binge-watching, and a polarizing teaching approach deemed "super boring" despite its animated delivery.
