Yeah, that's a big part of the problem.
And who is herself a Saberface. And has an Alter that's another Saberface, and a summer version that has a class that makes no sense for her to have. And all of this is (at least IMO) waaaaaaaaay too much investment into a joke that was really not funny to begin with.And there are so many Saberfaces, that they made an entire character whose shtick is killing Saberfaces.
If it were up to me, Nero would not be a Saberface and the entire Mysterious Heroine line of characters would simply not exist, nor any of the lore connected to them. Alas.
