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.

Sagiri was born in silence, no cry, no breath, no heartbeat, until a pulse of ancient energy tore through the air and marked him as the last child of a dead people. Cold, disciplined, and frighteningly calm for his age, Sagiri has spent his life hiding a power even he doesn’t fully understand. He does not smile. He does not fear. He does not allow anyone close. Because the thing living inside him 'The Echo' never sleeps.

I lived my whole life as a s*ave, bound by a leash.

And not just as anyone, but as my friend’s youngest grandson. So, what am I going to do now? Well, what else can I do?“I’m going to cause chaos.”
