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.

In the novel, the wealthy CEO male lead has a villainous stepmother. She put up a front of being nice and tender to him, when in fact she was bullying the male lead with her son. After she had successfully driven the male lead and his father apart, her ambition continued to grow as she attempted to take away the inheritance from the male lead. In the second half of the book, the truth came out — that the father had no feelings for her whatsoever but was merely using the two of them to hone his son’s character. In the end, both the stepmom and her son were sent to jail by the male lead after he took over the family business.

Yan Shuyu transmigrated and became the well-hated villainous stepmother, but she had transmigrated to the time before everything happened, and the male lead was still a foolish child. Only a fool would want to become the stepmother of a foolish child. Yan Shuyu took a longing look at her “assigned husband”, who was pretty much like the Sleeping Beauty, before she quickly packed up and made a run for it.

After that, Yan Shuyu checked out her $250 remaining on her card. She turned to look at her son, who was clinging onto her leg and asking for milk. She wanted to look up at the sky and howl. Is it too late to go back to become the male lead’s whetstone?
