user 166417 about 5 years ago The artist tagged this Touhou for whatever reason. No character name was given either, but she looks similar to Patchouli.
[KN] about 5 years ago There's also an "original" tag. Maybe the artist meant this to be a touhou-like OC?
OMGkillitwithfire about 5 years ago Most likely an OC. He never explained how this character is related to Touhou, however.
