Well, if she's carrying a large yo-yo in that long bag of herskk1 wrote:I think with the leather, smoking and speech I think she's trying to convey the tough girl image, what's the word "sukeban"?
If she was going all-out, she could use "atai" instead of "atashi"... Well, use of "atai" is extremely rare in manga/anime. (atai is like the female equivalent of "ore" for guys... except thousands of times rarer in practice).
I've no idea if she's deliberately trying for the tough girl image, or whether she developed it naturally after immitating guys a lot. But, it's nice. (Can she even immitate guys though? We never saw the ancient Shoujou immitate girls, so it could be limited to the same gender they were born as...)
