~ Eijiro's inner monologue during his battle with Kendo Rappa.

Eijiro Kirishima, also known as the Sturdy Hero: Red Riot or simply Red Riot, is a major protagonist in the 2014 Japanese superhero manga series My Hero Academia and its 2016 anime television series adaptation of the same name. He acted as a major character of the Shie Hassaikai Arc. He also appears as a major supporting character in the franchise's two films: My Hero Academia: Two Heroes and My Hero Academia: Heroes Rising.

Kirishima is a student at the prestigious U.A. High School training to become a Pro Hero. He is a part of Class 1-A of the Heroes Studies course. Eijiro's quirk, Hardening, allows him to harden and/or sharpen any part of his body at will.

He is voiced by Toshiki Masuda in the Japanese version of the anime, and by Justin Cook in the English version. The latter has also voiced Raditz in the Dragon Ball franchise and Eustass Kid in One Piece.


Kirishima is a young man of average height with a rather muscular physique, he has red eyes along with a small scar just above his right eye. His hair is dyed red and commonly spiked upwards, with two little tufts of it appearing like horns. His teeth are shown to be consistently sharp. Originally, Kirishima's hair was black and reached just above his shoulders.

His hero costume consists of two dark red, gear-shaped shoulder pads, a sash with a red "R" on it's centre, referring to his hero name; Red Riot. Along with this he has dark red boots, black pants with a ripped cape and black sleeves. His chest is left bare and he wears a black jaw guard that reaches around his head.


Kirishima has an outgoing, friendly and determined attitude, ready to take on any challenge that comes his way. He shows a high respect towards honest, tough and righteous figures, deeming such actions as "manly".

At the same time, he dislikes opposite attitudes such as cowardice or cheating. He has a very noble and willing personality, as well as being kind-hearted and friendly towards his fellow classmen. Even after defeating Tetsutetsu Tetsutetsu in the tie-breaker match during the Sports Festival, he offered a handshake in good sport, proving his fair and chivalrous demeanour.

Originally, Kirishima lacked confidence or self-esteem, and was ashamed when he could not help two girls who were being threatened by a gigantic villain, having apologized to them later for his lack of bravery during said moment. However, his attitude, as well as motivation to become a hero, was inspired by the hero Crimson Riot.

Thus, Kirishima chose to reinvent himself after being accepted into U.A. High, modelling his attitude of what a hero should be; selfless, fearless and determined.


While on the surface it may seem his only ability is hardening his body, he has shown his formidability on many occasions. For one, he withstood Kendo Rappa's barrage of attacks to rival Fat Gum's durability, but he wasn't good enough to force the monstrous Strongarm user to the defensive. Against Katsuki Bakugo, one of the strongest members of Class 1-A, he forced Bakugo on the defensive side due to his combat ability. In the beginning of the series he ranked 2nd in the U.A. Entrance Exams.

Fighting Ability

He has a variety of Super Moves that all start with the word "Red", a nod to his idol Crimson Riot. Two out of three of those Super Moves are all his own fighting style that take advantage of his quirk. His fighting style mostly aims to intimidate the opponent by charging first while letting the villain know his durability is considerable enough to cause worry. Of course, villains are normally more competent than that, and put up a fight, but Kirishima gets away with it because he's much like a tank. In close quarters combat, he fights tenaciously, even in the face of death. This is highlighted in his fight with Kendo Rappa and Hekiji Tengai even after seeing Fat Gum get deprived by them. Against Bakugo, he is seen attacking rather ferociously, and he is also able to break blades.



  • Enhanced Durability: Depending on his willpower, he can harden his skin. A shower of blades would simply sharpen against him, though it does take willpower to harden his quirk, and the more he hardens, the harder it is for him to move. With his Hardening quirk, he can also prevent significant burns from all sorts of flames. Bulletproof skin is another benefit of this quirk.
  • Enhanced Strength: With the density of his body increasing, his physical strength increases, and as one would imagine, he hits harder. In the U.A. Entrance Exams, he was easily able to harden his body and smash the Villain Bots with his arms. His strength has only increased since then, to the point where he was strong enough to potentially injure Kendo Rappa.

Super Moves

Red Riot Unbreakable

Red Riot Unbreakable: Kirishima's ultimate Super Move. He pushes his quirk beyond its previously known limits due to his sheer willpower, and becomes an intimidating rugged monster with skin that looks hard enough to make most villains think twice before punching him. His normal resistance to bullets, flames, and physical attacks are greatly increased in proportion to his strength, which is enough to damage Kendo Rappa and force Hekiji Tengai to block all of his attacks with his Barrier. The drawbacks are that it is not truly unbreakable, and can be worn down by a supernatural repetition of strong strikes. The other drawback is the time limit of 40 seconds. Depending on his willpower, he can reharden his body to try to make it last longer in the case of deterioration, as was the case against Kendo and Hekiji.


  • Red Riot honors the legacy of the Chivalrous Hero Crimson Riot.
  • Kirishima loves meat.
  • His favorite thing is manliness.
  • His peak popularity poll ranking was #4 in the Third and Fifth polls, behind Bakugo, Midoriya, and Shoto Todoroki in that order on both those polls.
