Since Ichibei is able to "cut" the names of objects, it might be possible for him to erase an object from existence by cutting away its entire name.

For example, Ichibei cut Yhwach's arm and it's now just "ar" and the strength of his arm is also reduced. Yhwach's arm could disappear completely if Ichibei cuts away the remaining letters of "ar".
