Eijiro Kirishima

Lore & Background

Kirishima's development centers on his personal definition of heroism. He initially looked up to the hero Crimson Riot, whose catchphrase "Let's go, eat it up!" inspired Kirishima's own sense of manliness. His rivalry with Bakugo pushes him to refine his combat skills, turning their mutual aggression into productive sparring sessions. A key turning point occurs during the Provisional Hero License Exam, where Kirishima fails the written portion but later passes after retaking it. During the Paranormal Liberation War, Kirishima faces Dabi's flames and Shigaraki's Decay. He activates a state he calls "Unbreakable," hardening his entire body to withstand lethal damage, allowing him to protect his allies from Shigaraki's decay. This moment cements his growth from an insecure student into a reliable shield for his class.

In Their Own Story

During the Paranormal Liberation War, Kirishima stands against Tomura Shigaraki, whose Decay Quirk threatens to erase everything it touches. As Shigaraki's decay spreads, Kirishima activates his Unbreakable state, turning his entire body into a hardened fortress. He endures the searing heat of Dabi's flames and the crumbling touch of Shigaraki's decay, refusing to retreat. His body cracks under the strain, but he holds the line, allowing his classmates to regroup and counterattack. This act of self-sacrifice embodies his belief that true heroism means enduring destruction so others can survive.
