イリス・ミリャ・サーペッタン

A Flat Chest girl who is traveling with Haruto. She’s actually a Serpettane princess, but she is hiding her true identity from Haruto and the others. She has an appetite bigger than her tiny body. She has a terrible sense of direction, so if you take your eyes off her for a second, she’ll get lost. Since she was very sheltered and hadn’t really been out of the castle, she’s quite ignorant of the outside world. She abides by her late father’s teachings and is hostile to the Big Breast Tribe. Flat Chests are said to be sensitive, so her super-flat chest is super-sensitive. She’ll cum just from having her nipples played with. [From MangaGamer]
