Hardening
Eijiro Kirishima's Quirk: a body hardened against attack.
Hardening is the Quirk of Eijiro Kirishima, the Class 1-A student known as Red Riot in My Hero Academia. It lets him harden his body. There is a limit to how much damage the hardened body can take, the hardening slowly wears off, and keeping it active costs him stamina.
Lore & Background
As a boy Kirishima tried to be a hero with a less developed version of the Quirk, and in middle school he froze when a villain threatened his classmates; a speech by his favourite hero, Crimson Riot, restored his resolve. Tetsutetsu Tetsutetsu of Class 1-B has a very similar Quirk, Steel, and the likeness makes the two friendly rivals.
Reader's Guide
During his internship with the Pro Hero Fat Gum, Kirishima develops a technique he calls Red Riot: Unbreakable and uses it to take down criminals after Tamaki Amajiki is shot. He admits after the Joint Training that outside combat his Quirk has very little application.
