~ Eijiro Kirishima

Eijiro Kirishima is a supporting protagonist in My Hero Academia, a manga series written by Kohei Horikoshi.


Eijiro Kirishima started out as a self-conscious and timid boy. Due to his classmates in junior high being more outgoing and lively than him, Kirishima became self-conscious over his appearance and personality. His self-image worsened after he found himself unable to stand up to someone threatening his fellow students. However, he turned his life around after watching an interview with the hero Crimson Riot. Crimson Riot's words inspired Kirishima to becoming a hero like his idol. Sporting a new hairstyle, Kirishima enrolled in U.A. High, the best hero school in Japan, to follow in Crimson Riot's footsteps under the Hero name Red Riot.

Powers & Abilities

  • Hardening: Kirishima's Quirk lets him harden any part of his body at will. Hardened body parts become jagged and sharp, and the hardening increases his physical strength and durability. While hardened, Kirishima's body becomes resistant to physical strikes, heat, and shock waves. If he needs to, Kirishima can increase the strength and resistance of his hardened skin for a short amount of time.
    • Red Counter: Kirishima hardens himself to block an attack before counterring with a strong punch.
    • Red Gauntlet: Kirishima rushes at the opponent, his hardened body shielding him from attacks, before hitting his foe with a single strong punch.

Alternate Forms

  • Red Riot Unbreakable: Kirishima hardens his body to its absolute limit, becoming extremely hard and rugged to the point of resembling a monster. In this state, Eijiro is nearly invulnerable to most forms of physical harm, and if his hardened form is broken, he can instantly return to his Unbreakable form. This form lasts around thirty to forty seconds.
