At the exclusive and mysterious Maison de Ayakashi, each elite tenant is protected by an elite supernatural Secret Service agent of their very own!

To get better acquainted--and, in some cases, reacquainted--with each other, the residents of Ayakashi Hall spend the last weeks of summer break at a seaside vacation spot. Between beach basking and tests of courage, Ririchiyo slowly warms to her new cohorts, but the one resident who never seems to betray his emotions is Miketsukami--and the group is determined to fix that! Will her efforts to unmask Soushi expose the truth of who he is--that is, who he is not?
