Although he doesn’t get the space he deserves in the final arc of the My Hero Academia manga, Eijiro Kirishima is among the most popular protagonists of the Shonen work signed by Kohei Horikoshi. But exactly What is Kirishima’s Quirk? and how does it work?

Eijiro is a kind and honest guy who acts as the glue for UA High School’s Class 1-A thanks to his always positive approach to things. Unlike his many peers, his favorite hero isn’t All Might, but All Might Crimson Uprising. He draws inspiration from this professional hero of the past to develop his concept of masculinity and his name as an aspiring hero.

In the fight is Kirishima known as Hero Red Riot. Always on the front line during battles, Kirishima owns the Quirk: hardening, that caused him so much insecurity and suffering in his childhood. It was just an accident that befell Mina Ashido that caused him to become the male hero he is today.

As the name suggests, the quirk: Hardening allows Kirishima to harden and sharpen every part of his body. To better understand this power, just consider that the name Eijiro is made up of kanji for cutting and sharpening. This Quirk is perfect both on offense, as Red Riot develops immense strength, and on defense. The aspiring hero of Yuei High School is indeed capable of withstanding powerful physical attacks, but also shockwaves and flames. Tempering has a major disadvantage, which is its limited duration and amount of damage that can be absorbed. Here we leave you 5 curiosities about the Kirishima Quirk.

After hard training, Kirishima develops this Red Riot unbreakable, a form that reaches maximum hardness, giving it a monstrous and fierce appearance. Initially, Eijiro can maintain this form for up to 40 seconds, but by training to take damage, he can improve the Unbreakable’s duration.
