Released under the Circus brand division 'Circus Fetish', the Tsui no Yakata series mainly focuses on maids.

Since a long time ago, the protagonist Masaki has been living without his mother. The difference in social standing between her and his wealthy father has always caused people to slander his mother and because of his father's inability to defend her honor, Masaki has never had a good relation to him.

Now, a pair of twin sisters, one innocent and the other precocious, visits the household and eventually gets hired as maids.
