Present Mic, known as Hizashi Yamada, is a professional hero and English teacher at U.A. High School. His Quirk, "Voice," manifested at birth when his newborn cries damaged the hearing of nearby medical personnel. This sound-amplification power generates destructive shockwaves capable of shattering structures, disorienting opponents, and causing physical harm, though its effectiveness lessens against underground or earth-shielded targets. He utilizes directional speaker equipment worn around his neck to focus his power and prevent indiscriminate damage. His signature techniques encompass "Loud Voice" for concentrated sonic assaults, "Loud-Out Shout" for area suppression, and "DJ Punch" for close combat. Physically tall and slender, he sports dramatically spiked blond hair during hero work, often secured in a bun casually. His hero costume features black leather attire, orange-tinted sunglasses, and headphones labeled "HAGE." Manga art depicts him with red eyes, while the anime adaptation gives him greenish-yellow eyes. Post-Final War, his hair grows longer, he adopts circular glasses, and wears an updated costume retaining core elements. His personality radiates a performative radio-host energy—expressive, energetic, and adept at engaging crowds, frequently addressing them as "listeners." Despite this exuberance, he possesses sharp deductive skills, being the first U.A. staff member to suspect a student traitor. He harbors entomophobia, causing intense distress around insects, and favors urban environments. Profound loyalty defines his relationships, particularly his enduring friendship with Shota Aizawa (Eraser Head), formed during their U.A. student days where he named Aizawa. This bond fuels protective instincts, igniting fierce rage upon discovering their deceased friend Oboro Shirakumo was reanimated as the Nomu Kurogiri, leading him to physically retaliate against the perpetrator, Dr. Kyudai Garaki. His background includes childhood years in the United States due to his father's work. Homeschooled by his teacher mother, he cultivated bilingualism and an affinity for radio through exposure to American broadcasts. Returning to Japan for middle school presented cultural challenges, but he resolved to pursue careers as a hero, educator, and radio host. At U.A., his optimism fostered friendships, notably with Aizawa, forming a duo renowned for complementary combat styles and unintentional comedic dynamics. Professionally, he balances hero duties, teaching, and hosting two radio programs: "Put Your Hands Up Radio" and "Banana Dreamer." His hero work emphasizes team coordination, using his Quirk to incapacitate foes for allies. At U.A., he announces major events like the Entrance Exam and Sports Festival, leveraging his crowd engagement skills. His involvement spans critical operations including the USJ incident, the Jaku Hospital raid—where he shattered Tomura Shigaraki’s incubation tank—and the Final War, combating villains warping near U.A. Official assessments rate his intelligence and cooperativeness highly (5/5), technique moderately (4/5), and speed lower (2-3/5), reflecting his support-oriented combat style. Alternate metrics award him top marks in "DJ Soul" (6/6 S+), highlighting his performative flair.
