Well, her weight is quite lower, compared to her devil ult.
from 761,97 to 734,6
no wait, her weight must be even lower, usually in the status screen, the +100 attack is calculated in right away? so her wait drops by another 40 total?
So her weight is only 13 higher than the non ult form.
Or maybe they forgot about that.
