The girls' dormitory of Shukusei Music Academy is home to one of the most talented young female musicians in Japan.

In this the top school, appearances count for everything, but in today's world the sounds of screams, whimpers, and dull moans can be heard echoing from the halls. The institution handy-man, Shusaku, cleans up following the girls and covers all of their dirty secrets, that she uses to blackmail them into some very un-ladylike private performances.

Shusaku can get paid to wash in the building, but his true calling is the opposite - sexually defiling and disgracing the innocent and-strung musical maestros.
