Fujiwara Naeka is a typical 17 year-old high school student with copious amounts of cleavage. Or so we thought. She`s really one of two surviving heirs of a tycoon who has the right to inherit his mass fortune when she turns 18 in half a year. Fubuki, a young and beautiful maid with a nail studded bat, and Kogarashi, a big burly maid guy with a mask and serverly inhuman powers, have been assigned to keep Naeka and her brother Kousuke safe from those who would plot their demise, and to steal the fortune she would inherit.
