Synopsis
Himawari Hinata has just transferred to Shinobi Gakuen to train toward becoming the greatest kunoichi she can be. Ever since a ninja saved her when she was young, she has dreamed of becoming one herself. On her first day, she meets Hayato Madenokoji, a new transfer teacher, who saves her life. Hayato possesses no ninja skills or traits; he is instructing the ninjas about normal society in order to pay off a debt. However, Himawari notices that Hayato bears the same mark on his neck as the ninja who saved her as a child.
