That TL;DR summaryzation is not precise enough.

Shiki R can kill fucking Servants like paper. In Fate/Extra, she already killed around 99. OP is little.

And while she can't "cut reality", her 3rd personality can kinda-sorta alter it. Well, not really alter reality, but kill this reality and inmediately make a new reality where the change is in place. Not the same. From a certain point of view, even stronger.
