Hanaukyou Maid-tai

After the death of his mother, middle schooler Tarou Hanaukyou is sent to Tokyo to live with his grandfather. What he finds instead is far from an ordinary home: a sprawling mansion staffed by hundreds of maids, all ready to greet him as their new young master.

The head maid, Mariel, shows Tarou a brief video message from his grandfather declaring that Tarou is to inherit the entire fortune. Still trying to make sense of the sudden change, Tarou begins adjusting to mansion life—where the devoted household staff will go to extreme lengths to cater to him.
