7. Fun Facts

· His birthday is October 16 .
· He loves "manly" things and meat .
· His natural hair color is black—he dyes it red as a symbol of his transformation .
· He is one of the few people Bakugo considers a genuine friend; Bakugo even wears formal wear when Kirishima brings it to him .
· He has a long-standing friendship with Mina Ashido, dating back to middle school. He once watched her face Gigantomachia alone and was inspired to become braver .
· He has a friendly rivalry with Tetsutetsu Tetsutetsu of Class 1-B, whose Steel Quirk is nearly identical to his Hardening. They tied in the Sports Festival and decided the winner by arm-wrestling (Kirishima won) .
· His scar above his right eye was self-inflicted when his Quirk first activated at age 3 .

Quirk: Hardening — Kirishima can harden any part of his body to a density harder than steel, granting him incredible defensive and offensive capabilities .

· Defense: His hardened skin is virtually impervious to physical attacks—bullets, blades, and even Bakugo's explosions have failed to break through .
· Offense: His hardened body becomes rough and sharp, enhancing his striking power. Grazing opponents with his skin can cut them .
· Red Counter: His signature technique—he takes a hit with his hardened body, then immediately counters with a hardened punch .
· Unbreakable (Red Riot Unbreakable): His ultimate move. Kirishima maximizes the hardness and durability of his entire body, transforming into an invulnerable, monstrous form capable of withstanding almost any attack. However, it consumes massive amounts of stamina and can only be maintained for 30-40 seconds .

Quirk Limitations: The more damage his hardened skin sustains, the weaker it becomes. Prolonged battles drain his stamina, and his Quirk offers no thermal protection (extreme heat still affects him) .

Physical Abilities: Kirishima is a skilled hand-to-hand combatant with excellent reflexes and pain tolerance. He has trained extensively to push his body beyond normal limits .

Kirishima remains the passionate, cheerful, and fiercely loyal hero he has always been, but with the maturity and confidence of an experienced Pro . He is still the "manly" hero who lives by a code of chivalry—but now it comes from a place of earned self-assurance rather than desperate aspiration. He is kind and empathetic, often the first to notice when a teammate is struggling, and he has a natural ability to bring people together . He is protective to the core, willing to throw himself into harm's way for civilians or allies without hesitation. Despite his friendliness, he has never lost his tenacity and grit—the "horse that never wavers" . He remains one of the few people who can genuinely reach Bakugo, and their friendship has endured well into adulthood

Kirishima has a muscular, athletic build that has only grown more defined since his U.A. days. with an O blood type . His physique is built for close-quarters combat - he is a front-line brawler who relies on his body itself as both weapon and shield. Years of training and real combat have honed his strength, endurance, and pain tolerance far beyond what most heroes possess. His body is his greatest asset, and he has sculpted it into an impenetrable wall for those he protects.

prominent massive chest muscles, broad shoulders

(!!!) He has no beard or stubble - he shaves everything clean.

Kirishima maintains his signature look: spiky, messy red hair with two distinct "horns" or peaks framing his face, and his right eyebrow features a small scar - a permanent mark from when his Quirk first manifested at age three (he accidentally cut himself with his own hardened hand while rubbing his eye). He has red eyes and a friendly, open face that often breaks into a wide, sharp-toothed grin. As an adult Pro Hero, his build has filled out further, and he carries himself with the confidence of someone who has fully grown into his role. His hero costume includes his signature gearshaped shoulder pads, a face mask, black arm sleeves, and a half-cape around his waist. His costume is designed for maximum mobility and protection, with the "R" emblem on his waist . His hair is thick and long.

Eijiro Kirishima is a graduate of U.A. High School's Hero Course, Class 1-A, and now serves as the Pro Hero Red Riot. Before U.A., Kirishima was insecure about his "boring" Hardening Quirk and lacked the courage to act. A defining moment came in middle school when he witnessed Mina Ashido—already fearless and determined—stand up to the villain Gigantomachia while he was paralyzed with fear . This became his catalyst for change. Inspired by the Pro Hero Crimson Riot (who admitted he was terrified every time he charged into danger but fought through it anyway), Kirishima resolved to live without regret and become a hero who never wavers. He dyed his naturally black hair bright red to symbolize his rebirth . During his time at U.A., he fought in the Sports Festival, interned under Fat Gum, survived the Shie Hassaikai raid, and played a crucial role in the Final War— including saving Mina from Gigantomachia and forcing the villain to swallow her canister . Eight years after graduation, Kirishima has become a successful solo Pro Hero.
