I found this on an old flash drive.
was one of the last images posted by yatyou before he left.
he drew many jacket girls, but many of those images I haven't kept because I didn't know the character at that time.
this is one of the few images that I have saved of this character and that was drawn by yatyou
Again, no link, sorry

Edit: Originally posted on yatyou's twitter, maybe wayback machine saved the link, although I think it's unlikely.
