So much love! Hinagiku investigates her feelings toward Hayate! Saki goes to a marriage interview! Britney loves Senpai! And a new mechanical butler loves to corner the market on butlering.
The mechanical butler is actually the lion's share of this book. With Hayate studying hard for exams, he's been given some time off and the robot butler is called in to cover his duties. And if you've made it to book 10 of this series, you are expecting that to go wrong in a certain sort of way. And it utterly betrays those expectations in a pretty fun way. :)
