Stiffening

Reinforce is a Quirk used by Shikkui Makabe.

Description
This Quirk seemingly allows Shikkui to harden held objects.

Shikkui can make anything he touches harder than even concrete. This is done by rubbing or kneading the objects together with both hands.

This Quirk has no effect on living beings.

Trivia

 * This Quirk is the inverse of Hardening, which only hardens the user's body itself.
