Decay

Disintegration is a Quirk used by Tomura Shigaraki.

Description
Tomura's Quirk allows him to destroy anything his hands touch by making them crumble down to bits.

The disintegration will only occur when all five fingers touch the target, indicating that the activation of the Quirk is not voluntary. As such, Tomura is often careful with his hands when touching objects he doesn't want to destroy.
