I have an extensive list of manga. Trouble is, I can't remember what half of them were about. I tagged this one as interesting, but I can't find it again on here or google. Searching "Hara no E" on here gives over 2000 results- anything with the word "no" in the title. If anyone can provide a link, I would be VERY appreciative! ;*
