Galactic knight: Apocalypse system Activated! - Chapter 26: The Wall Galaxy...

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.

Shen Weiyi has a younger, boy-next-door boyfriend whose allure lies in his height, long legs, and strong torso. With a wild mind and a talent for flirting, the eighteen-year-old Jiang is impulsive, fun-loving, and fickle, exhibiting both innocent and wolf-like traits at the touch of a button. Beloved by countless girls, he always thought Shen Weiyi, who would do anything at his mere call of 'sister', would forever indulge him, only to find she suddenly doesn't want him anymore.Breakups are breakups; whoever regrets it is a dog.Shen Weiyi, once red-eared and compliant to his every whim, now won't look back, leaving an eighteen-year-old Jiang's genuine liking turning into a resolute declaration of disinterest. 'Jiang,' she says, 'I date for happiness, not for extra headache.'Later, a desperate Jiang tries everything for her, getting injured in the process and lowering himself to the dust, only to see her blooming in another man's arms, which drives him to a jealous rage.Sheng Ting, the genius of the Z University, untouchable and seen by everyone as the embodiment of purity and restraint, had decided the names of their unborn children upon his first glimpse of Shen Weiyi.[Childhood friend VS Sudden love, not seeking the adoration of the whole world but asking to be your one and only exception in life.]

Suddenly being thrown into the world of the novel and possessing a pretty much fucked up character made him have no choice but to continue his life as a new identity.

And just like any sane person that transmigrated into a book, of course, he would destroy every red flag that stood in his way.

Yet, unbeknownst to him, every single thing he did was just wrecking the storyline more and even more; to the point that the plot had become utterly screwed, thanks to him.
