When he was three years old, Eijiro Kirishima woke up in the middle of the night to use the restroom. When he rubbed his eye, his Hardening Quirk manifested for the first time. This made his hand harden and caused Eijiro to cut himself, which left a scar on his right eye. Afterwards, the young Eijiro initially hated his Quirk for hurting him. Despite this, Eijiro began to admire the hero Crimson Riot, whose Quirk was very similar to his. This admiration caused Eijiro to adopt Crimson Riot's ideology and mentality that, as long as he has a manly spirit, then Quirks don't even matter. All that is needed is to train hard to cover for the Quirk with the spirit. Eijiro followed those tips and trained for years to strengthen himself.Eight years after the Final War, Eijiro has graduated from U.A., becoming a Hero alongside his classmates, previously working as a Sidekick for Fat Gum, before going independent to become the current No. 12 Pro Hero.
