It's Kokoro! She's one of the main characters in the plot of TH 13.5 (Hopeless Masquerade, a fighting game), and the game's final boss. If memory serves, not much of that game has been translated yet, nor are there any plans to finish the translation.
In the game, her masks operate as a way for her to express her emotions, and much of the plot revolves around her losing one of them. Though by the end of the game, she has learned to cope, and express some emotion without her masks. She's easily one of the most moe characters in the Touhouverse. Here's hoping for some proper yuri for her before too long!
This story was cute. Could've probably used a bit more blushing, though.
