Does anyone know what anime 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 animation looks similar though.. ^^;

i think shes from Hidan no Aria i did a picture Google search 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 favorite Anime's. Reki is a sniper.

That girl is Reki from Hidan no Aria the scarlet ammo, her motto is I am single bullet, It doesn't have heart and goes straight ahead
