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.

Shu Yu has passed through the book, and has become a poor cannon fodder who was implicated by the dead female supporting role and only appeared twice and was finally exiled for thousands of miles.

After finding that he could not change the result, Shu Yu decided to eat, drink, lie down and wait.

Who knew that the exile had not yet come, but she was suddenly told that she was not the daughter of the Shu family.

Her biological parents were peasant households who lived so hard to make ends meet that their house was leaking.

And the Shu family decided to obliterate her in order to hide her blemish.

Shu Yu: Come on, I can’t kill you.

Returning to his biological parents, Shu Yu finally sighed as he looked at the plate of pickles and a bowl of porridge on the table and placed in front of him, as well as his parents’ nervous and bewildered expressions.

You can’t lie flat, or you’ll starve to death.

- Description from novelbuddy

This is the story of a young man who was reincarnated as a dragon with a near-insatiable curiosity. Initially sparked by questioning his own reincarnation, he quickly gets lost in the endless world of magic, using his deep understanding of advanced sciences to learn the laws and properties of a new type of energy known as mana.However, soon enough, the table would flip, and he would begin using that very same energy to expand his knowledge of science, to the point that he would begin questioning his own understanding of the world.Although not his original intention, with the combination of his intelligence, expanding curiosity, and the 'miracles' that occurred to allow for his existence, he quickly found himself climbing the mountain of strength as if it were a small hill before eventually climbing to a point where it seemed as if he himself was the peak itself.Even if.. that was never the case...There is mild gore, and profanity is 'censored' toward the beginning, but not later in the story.
