MTL - General: Traveling Frog, Starting Blood and Following the Limit - Chapter 283

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.

To correct the mistakes of his past, a young man is forced to narrow the space between science and witchcraft, as he ventures on a quest to save his world from complete destruction.

Ruan Yōu became a brainless cannon fodder in the Mary Sue entertainment novel, with fair skin, a beautiful face, and long legs. She was criticized by fans as “trying to climb up” after looking at the top male lead too much, and the female lead took the opportunity to suppress her, causing her career to plummet.

Ruan Yōu accepted her fate and decided to retire from the industry to study finance and live a laid-back life as a salted fish.

However, her billionaire parents and CEO brother came knocking on her door, their eyes filled with guilt.

Ruan Yōu: ?!

Retiring forty years early and living a life reclining on the couch as a rich woman has just arrived!

Fu Jiazhan had known since he was a child that the little princess who had been betrothed to him had gone missing.

Mrs. Ruan spent her days in tears, holding his hand and choking out, “If Yōuyōu hadn’t gone missing, you and she would be about the same age, and you could have grown up together and taken care of her.”

Fu Jiazhan remembered those words, and when Yōuyōu returned to the wealthy family, he prepared to take care of her as her fiancé. But his future mother-in-law found three rivals for him.
