Hardening (硬こう化か, Kōka?) Gives the User the ability to harden and sharpen any and all parts of their body, causing flesh to become jagged and rock-like. This power has a limit to how much damage the User’s hardened body can withstand, which causes the Hardening itself to slowly dissipate.

This Quirk also provides an enhanced strength that allows the User to break through most obstacles, becoming dramatically more powerful in their “Unbreakable” form.
