Earth Release: Hardening Technique

By utilising earth-based chakra, the user creates an armour of rock that encases their body. The armour can also be used to create extendable weapons to strike a target with.

Sadai has demonstrated that he could use the armour to alter his physical appearance, akin to a costume and mask, giving himself a larger physique and different face. However, his usage also adds weight to him, slowing him down.
