Shinobi. They existed in the shadows long ago, far away in the Warring States Era. Hiding among people, they search, influence, deceive, break, and kill. They existed in the shadows to take on every single dark work. One day though, they began to disappear from the hearts of people and became a shadow spoken of in legends. However, even if they disappear from the hearts of people, the work that people do does not change. The need for them among the people in this dark world still continue, thus the shinobi continue to exist.

Currently, shinobi employers are politicians and executives of corporations. Among those who wield considerable influence, there are individuals who use the shinobi as tools for their own personal gain. Shinobi who move in the darkness like that are known as evil shinobi. The government has devised a plan to create virtuous shinobi who rise up in opposition. These virtuous shinobi are raised by a secret facility within the government specifically for shinobi. This special agency tasked with the specific task of raising virtuous shinobi is known simply as Shinobi Studies. It is hidden inside of a famous and massive prep school known as National Hanzou Academy which has over 1000 students in enrollment.

This story is of virtuous shinobi dedicating their youth to fighting against evil. This tells the path of love and courage taken by five girls who were placed into the National Hanzou Academy’s Shinobi Studies program.
