Damn. I big Ayase fan, so I'm kinda disappointed in the lack of careful Quality Assurance/Control in this image (all the random lines and brush strokes). It's like the artist got tired of the clean-up work and just said, "MENDOKUSAI~!" and just did whatever quickly, saved, and posted it on Pixiv. >_<
Ayase is indeed the least loved character in the series - it lacks from screentime to fanart alltogether. :(
