I admit I know nothing about this character or the show she's from(and if I did I'd probably already know the answer), but.... what in gods name is she holding? O_o
勝つ katsu, to win. Katsuru is not actually a word, これで勝つる is apparently a joke on japanese boards. I can't seem to find the origin, though it looks like an FF joke made by someone named ブロント: 「もうついたのか！」「はやい！」「きた！盾きた！」「メイン盾きた！」「これで勝つる！」 - 'You're here already!' 'That was fast!' 'He's here! The tank is here!' 'The main tank is here!' 'Now we'll win for sure!'
It might have started as an involuntary mix between katsu and kateru. Like when people type things such as "I can do not believe it". Not exactly a typo, but two different phrasings getting mixed up.
