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.

As the youngest son of a top chaebol in the Blue Star entertainment circle, Lin Zhibai thought that his life was just to eat and wait to die.

Until that summer.

The system fell from the sky, and he awakened the memory of his previous life.

“Can’t I properly read stallion novels anymore!”

Shen Yuan transmigrated into someone who’d tormented the young male lead almost to death, the scum villain Shen Qingqiu.

It must be known, the original Shen Qingqiu ended up being carved alive by his disciple, Luo Binghe, into a human stick, a human stick!

Ten thousand “fuck your moms” rampaged through Shen Qingqiu’s heart:

“It’s not that I don’t want to cling to the male lead’s thighs, but who made him so fucking black. The type who seeks thousand-fold retribution!”

Why have all the female lead’s scenes been forcibly given to him.

Why, as a scum villain, does he need to constantly sacrifice himself, blocking knife and gun for the protagonist!

Shen Qingqiu: “…I think I can still save him, one more time.”

A gong who starts as a loyal dog of a small white flower, and ends up as a blackened, mental case of a maiden X a refined scum villain of a tsukkomi-holic shou

This is actually a dogblood story about a master-disciple pair never doing honest work, fighting monsters, and engaging in romance.

It’s also a story where the villain personally witnesses how the male lead transforms from a little sheep of a white lotus into a dark tyrant O(∩_∩)O~
