Kamen no Maid Guy S01

"Fujihara Naika" is a 17-year-old ordinary high school student. However, this is just an appearance. She is one of the two remaining heirs of a great wealthy person, who has the right to inherit a vast fortune in six months when she turns 18. The responsibility of protecting "Naika" and her brother "Kusuke" from those who plan to get rid of them and steal the inheritance falls on "Fubuki", a young and beautiful servant, and "Kogarashi", a sturdy male servant with a mask.
