Izayoi Sakuya from Touhou Project.
Please as well visit my Pixiv version. I've got a character-only (without background) in it.[link]
Was aiming for sending this pic as Pixiv's Touhou Project Retaisai 10 event, but didn't make it in time T___T awww...
However, the Scarlet Devils won the event. Guess this pic won't be that of any help anyway XD
I'm into Touhou lately (mostly Scarlet Devils). Probably because of doujins I've consumed in the last few weeks ahahahaha.
