Hanaukyou Maid Tai [TV]

Hanaukyo Maid Team is about a young boy, Taro Hanaukyo, who has inherited a vast family fortune and, more importantly, the hundreds of employees working at the family mansion. While dressed and referred to nominally as ‘maids’, there are discrete albeit sometimes unusual departments for most of the employees (including Defence, Science, Catering, etc.). Presumably the various extensive projects in the house pay for most of its expenses.
