Shinobi Quartet

Summary

Chouko Manaka is the next heir to the prestigious Manaka family. Now she is entering high school and she has had enough with being surrounded by bodyguards, who have prevented her from making any friends. Her father is still worried though, so he makes a deal with her. If she transfers to Mizonoo high school, where many of the students are also studying to be shinobi and can get one of these people to be her right-hand man by graduation, he'll consider her to be able to make decisions for herself. On the first day of school Chouko meets the son of their butler, who suddenly declares that he wants her to be his master?! (Source: MU)
