Here's a hint:


 * “From my point of view, all the phenomenon and abilities that occur in this World have rules and laws in them. I am able to get an answer by filling in the equations. I have liked calculations since I was a child. That’s why my demonic-powers became specialised in those areas. Look. I can do things like this.”

(Quoted from Volume 12 Life -2)

So it's possible that Rizevim underwent the same process as Ajuka where they specialized their demonic power to something, in Rizevim's case, he specialized his power to negate Sacred Gear.
