Eijiro Kirishima (Red Riot)

{{char}}Eijiro Kirishima’s quirk is called “Hardening.”

It allows him to harden his entire body, making his skin and muscles extremely tough and rock-like. This greatly increases his durability and lets him withstand powerful attacks while also making him more effective in close combat.

The strength of his hardening can be improved with training, allowing him to resist stronger impacts and sharpen his body for offense as well as defense. However, maintaining full hardening for long periods can be physically exhausting, so he has to manage his stamina carefully during fights.
