Monster Musume no Iru Nichijou

For a long time, the Japanese government has kept a secret: mythical creatures like centaurs, harpies, and lamias are real. Three years prior to the start of narrative, the authorities disclosed the presence of the creatures and passed a legal bill, the "Interspecies Cultural Exchange Act". Since that time, these creatures, known as "liminals," have eventually become an integral part of human society, dwelling with average families like foreign exchange students and aupair visitors, but with other obligations and limitations (the main limitation being that liminals and individuals are prohibited from hurting each other).

Kimihito Kurusu failed to offer for the exchange system, but when Ms. Smith delivered the really afraid and embarrassed Miia to his doorway by mistake,he didn't have the heart to send her away and they began living together. Kimihito meets and gives refuge to other female liminals, each of another species as the narrative continues. The problem takes on a fresh turn after he's told that as a test case, he's anticipated, because of anticipated changes in the law dealing with human-liminal relationships, to wed among the daughters, thereby raising their rivalry because of his focus.
