I pretty much don't understand where this NTW-20 1-hitting SF T-Dolls thing.
At max, her skill has 8 times multiplier, and combined with the fact she has one of the highest damage among RF and uses AP rounds, she makes armor unit look like a joke. You can one shot any armored bosses if you set the team right with her. Its basically a meme NTW smacking SF, especially Ouro-chan.
