Yeah, holy Jesus on a bicycle. Thats one insane high level of detail artwork she has.
She is not bad thb.
Now granted. she is a bit of a gimmick mix up with her secondary abilities being Def. oriented. And as we know the Crit girls are not exactly on the durable side.
HOWEVER > As someone who uses Mace loli chan and Anewaifu, who does have a Defensive buff I can attest that, while not often, there are some battles where the improved Defense does come into play and makes a difference between being one shotted or not.
Honestly this girl would great with them in a single team, as it would stack that Deffensive buff higher, while still rocking pretty solid crit build just from those 3.
