Title: 1/8 Girfriend (1/8 Kanojo Hachi Bun no Ichi) [link]
Length: 157 pages (5 chapters)
Description: This is the story of a girl, Isaka Asuha, who wakes up one day turned doll-sized in her childhood friend’s room, completely naked. After he finds out, they try to turn her back to normal doing some ecchi things… because that’s the best way to do it, obviously!
Opinion: This manga is really sweet, I recommend it for those who like romance, but if you’re looking for something more perverted, I don’t think you’d like this one. Lots of sexual stimulation, huge fingers, you get the idea…
