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.

A freak accident puts an end to that.As Leslie lies dying on the road, watching Calliope breathe her last, she curses her helplessness. Calliope’s crochet fox seems to hear her. It opens its mouth and asks, “Do you want to see your daughter again? If so, follow me. Her soul has already left for another world.”Leslie agrees. That’s the last thing she remembers before losing consciousness. When she opens her eyes again, she finds herself—or rather, her soul—standing beside her unconscious body on a hospital bed.“How is this supposed to help me find Calliope!” she exclaims.“This is not your body. Your body is dead. This is my original host, Charlene Li,” explains the toy fox. “You can possess her body to find Calliope, but if you do, you must finish her uncompleted mission for her.”“And what mission is that?”“To marry the second most eligible CEO in the city.”‘This,’ Leslie concludes, ‘is a scam.’ But she has no other choice.**********Meanwhile, the second most eligible bachelor in the city, Calix Xu, is patting himself on the back for thwarting his grandmother’s attempts to marry him off.

Grandmother can do nothing now.”But… why is he seeing his newly-wedded wife hovering beside her own body?Before he can react, his wife—the moving one—floats towards him.“Husband! Help me find my child!”“Your child?” Calix asks weakly before doing the only reasonable thing he can do in such a situation.He faints.
