Shinobi Shijuusou
Shinobi Quartet;

Chouko, heir to the powerful and long-established Makana family, has never been able to make friends because she is constantly surrounded by bodyguards. After repeated attempts to escape them, her father offers her a chance to change her life: she must enroll at Mizono High School, a school for shinobi, and earn recognition as a master from one of its students. If she fails, she must follow her father’s orders forever. At Mizono, one shinobi hugs Chouko and declares that she is his master. How will this unexpected bond shape her time at the school?
