Yeah, this isn't History EE, you need to full erase something from all point of time, not partially removing something past and future only, leaving the present intact. Also EE is existence erasure, history EE is that you erasw the history itself and the existence tied with it to make them disappear. Somehow Izumo still physicallg exist is an anti-feat against EE in the first place, let's alone History EE, unless you have proof that Izumo was already erased and somehow existing in a nonexistent state, but evidently it seem like it still exist normally and only its past and future was lost
At best i can see causality and fate erasure that almost do nothing in a match, decorative abilities
