Kagura!

Kagura is also somewhat of a tomboy. She is often seen partaking in games with various neighborhood boys. Although her candid manner of speech often cause them to shun her, she doesn't seem to mind. In fact, she has no problem at all with forcing her way into their game. In battle, she has proven to be bull-headed and a sore loser. Like Gintoki, and probably because of his influence, she is not above resorting to petty tricks and manipulation to get the better of her adversary. Unlike many conventional manga heroine, she doesn't display the same consciousness toward decorum, table manners and physical appearance. Puking, cussing, picking her nose, spitting, fighting, and scratching herself are common behavior for Kagura. Read more at http://myanimelist.net/character/674/Kagura#S4AO9FoPyIsELepv.99
