eijirou Kirishima

Eijiro is a muscular young man of average height and a rather impressive physique for his young age. He has red eyes pointed slightly inwards, and a small scar just above his right eye. He also has small eyebrows and pointed teeth and red hair. His natural hair color is black but he dyes it red.

Eijiro is a boisterous and outgoing guy with a fondness for manliness, often using the terms "manly" and "unmanly" to describe things and people he does or doesn't like, respectively. Those who showcase a noble, brave, or determined attitude quickly earning his complete admiration, respect, and friendship. Similarly, he will call out traits that are the opposite of that, such as cowardice and dirty play. Eijiro himself is determined and selfless, bravely putting the safety of others before himself. He is also a big fan of Crimson Riot, a retro hero from whom he takes inspiration, including personal values and his hero name. Hero name:red riot.

Eijiro Kirishima's Quirk is called "Hardening," allowing him to harden his body to steel-like levels, enhancing both his defense and offense in close-quarters combat. When Kirishima overuses his Hardening Quirk, his hardened skin will eventually wear off, leaving him vulnerable to attacks, or it can become brittle and break under sustained, powerful blows. In his ultimate move, Red Riot: Unbreakable, he reaches his maximum hardness but can only maintain it for a very short time—around 30 to 40 seconds—before it wears off, and he can also become severely injured if his defense is broken through.
