That's why they are called mutation of Devils. Rizevim has a cheat-like ability but isn't that the same for Sirzechs and Ajuka. Sirzechs can transform into a POD himself which allows him to practically destroy everything. Ajuka has the ultimate technique to control all phenomenon with just equation. Those are cheat like ability too, just not related to Sacred Gear.
