Shigaraki's itch is a symptom of his quirk, Decay. His quirk causes his body to constantly decay, leading to a constant, uncomfortable itching sensation. This is a side effect of his quirk's ability to decompose anything he touches.
Here's a breakdown of how Shigaraki's quirk works:
- Decay: Shigaraki's quirk manifests as a decaying aura that surrounds his body. This aura can decompose anything it touches, including flesh, bone, and even inanimate objects.
- Constant Decay: The decaying aura doesn't stop when he's not touching something. His body is constantly decaying, resulting in the itching sensation.
- Severity: The severity of the itching varies depending on the level of decay. The more his body decays, the more intense the itching becomes.
Shigaraki's constant itching is a testament to the destructive nature of his quirk and serves as a constant reminder of the power he wields.
