I found her in a comic collection of Uncanny X-Men. She was in a reprint of the comic "Tokyo Story" (Issue #181). Unfortunately, since the collection was monochrome, I do not know what are her colours, so the most I could do is redo her is SAI (since the original sketch was a huge mess).

If anyone wants to give her real colour, then look for the higher-quality source image here!
