A Harem Manga series created by Okayado about Kurusu Kimihito, a young man who takes part in a "Cultural Exchange Program" to help humanoid beast creatures integrate into society. He is assigned a "Lamia" named Miia who falls in love with him during her stay.


Written and illustrated by OKAYADO, it ran in the Monthly Comic Ryu in March 2012.



A manga series following Kurusu Kimihito, a 20 year old volunteer for "The Cultural Exchange Between Species Bill", a law instituted in order to get humans and Extra-species people (monster girls) to associate and build friendship and understanding. As a volunteer for the extra species act, Kurusu volunteered to take in a member of an Extra species, and in his case his resident was Mia A female Lamia. As the Series progresses, more and more monster girls end up staying at his house, each competing for his affection and possible marriage.

Kurusu Kimihito (来留主 公人 Kurusu Kimihito)
Hair Color: Black, Eye Color: Red
Species: Human
Gender: Male
The protagonist of the series, and a volunteer for the extra species volunteer program, he is surrounded on all sides by monster girls. He's your average Harem protagonist with no defining features other than his attraction towards monster girls rather than humans. All the girls living at his house appear to have feelings for him, referring to him by different pet nicknames.
Miia (ミーア Mīa)
Hair Color: Red, Eye Color: Yellow
Species: Lamia
Gender: Female, B-W-H: 86-55-90
A lamia (Woman with the lower body of a snake), and the original (official) resident under the extra-species transfer act, she has had feelings for her "Darling" since the beginning of the series. While she doesn't exactly like the influx of girls living with her and Kurusu, she typically is accepting of them, as long as they acknowledge her as the "Main girl".
Papi (パピ Papi)
Hair Color: Blue, Eye Color: Orange
Species: Harpy
Gender: Female, B-W-H: 70-51-75
A childlike harpy (Bird girl) with a tendency to run away from her host family, she met kurusu through kidnapping him. (to get her food) Papi has an innocent personality, more due from a lack of intelligence rather than personal morality. (The rest of the cast often refer to her as a bird brain). Despite her youthful appearance, she is just as old as both Miia and Centorea.
Centorea Shianus (セントレア・シアヌス Sentorea Shianusu)
Hair Color: Blonde, Eye Color: Blue
Species: Centaur
Gender: Female, B-W-H: 103-61-???
A centaur (woman with the upper body of a human and the lower body of a horse) who has a very strong sense of morals and who self-identifies as a knight, she sees Kurusu as her master. Like Papi, she has a very innocent personality, but this is likely due to centaur culture, rather then a lack of intelligence. Centorea and Miia see each other as the biggest rival for their "darlings" affection. Despite this rivalry however, Centorea considers Miia to be a good friend.
Suu (スー )
Hair Color: Green, Eye Color: Green
Species: Slime
Gender: Female
A slime, your typical RPG monster, who takes on human form. A very simple creature (even more so then Papi) she typically takes on the attributes and personalities of the rest crew. It is unclear quite how intelligent she is, if she is simply mimicking everyone else, or has higher level thinking. She does seem to be quite attached to Papi and they have a sister like relationship.
