Does anyone know what アニメ this girl is from?

..I took a wild guess and thought she may be from "Zombie Loan"..? But I looked it up and I didn't see her at all.. The アニメーション looks similar though.. ^^;

i think shes from Hidan no Aria i did a picture Google 検索 and thats the name that came up

yes her name is Reki from the Hidan no Aria series

I was sure that she was a character form Hidan no aria but I haven't watched the series... does anyone know if its any good?

That is Reki from Hidan no Aria. It's one of my お気に入り Anime's. Reki is a sniper.

That girl is Reki from Hidan no Aria the scarlet ammo, her モットー is I am single bullet, It doesn't have ハート, 心 and goes straight ahead
