When The Cute Kunoichis Spied on Their Teacher's Secret is a light novel written by Kazuma Kamachi and illustrated by Ryuushi Tajima.

The story takes place in a world where Japan never ended their isolationist phase, and agents from foreign powers are always threatening to steal the country's advanced technology. In order to combat this threat there has been a resurgence of ninjas that use Strategic Martial Arts, techniques that combine cutting-edge modern technology with a traditional foundation of martial arts and ninjutsu. The story follows Souha Sugiyado, a 17-year old ninja instructor and former ninja prodigy who was forced to retire from active duty by the wounds he suffered in his last mission. Souha's four students are all kunoichi who have all gained the rank of Elite Ninja, the highest official rank available to ninja. However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

Every novel has a low IQ supporting female that serves as a foil to the female lead’s good and beautiful sides. She’s the stepping stone on the path of love between the male and female leads, destined to live her life doing stupid things until her tragic end.

One day, all of the villainous supporting females came to their senses. They began to rebel! And quit! For the sake of world order, the System found a human to take their place.

World 1: The female lead risks her life to shield the male lead while the supporting female quakes in a corner (and watches the show)

Male Lead: ?? So you never loved me.

Supporting Female: He finally found out, looks like my job was a success. The end of the year bonus is mine!

Male Lead: ?!

A fun and breezy quick-transmigration story~
