Fujiwara Naeka, a 2nd year student from Shuuhou Seiha Private High School, will be turning 18 in half a year's time. However, little does she know that she & her brother, Fujiwara Kousuke, are the remaining heirs to inherit their grandfather's fortune. In order for that to happen, Naeka has be to be 18 years old. Therefore Fubuki, a young and beautiful maid, and Kogarashi, a burly maid guy with a mask, have been assigned by their gramps to take care of Naeka and Kousuke everyday's household chores and protect them from any possible assassinations by people who are eyeing on the fortune before Naeka turns 18.
What makes people love and hate about Fujiwara Naeka is her breast size. Her female friends are all jealous about her oversized chest, on the other hand, guys are much attracted to & curious about it. All these are giving Naeka a headache because worst of all, her maid guy, Kogarashi is a big time ecchi who always does perverted actions on Naeka when he doesn't know it's sexual harrassment.
Fujiwara Naeka also takes part in her school's Kendo club and she plays the role of a vice-captain (Fukusho).
