MTL - Evil Emperor’s Wild Consort - Chapter 1694 Three years (twenty)

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.

Some say he is the bad apple in a basket, that he’s rotting everything around him with disgrace and corruption.

Some say he is the biggest scum of the South Zhanbu Continent, that he’s colluding with the dark sects to cheat, steal, and commit all manner of atrocities.

Some say he is the most wanted playboy. “Lock your daughters at home to keep Fang Xing away!”

To all of those people, “That’s right, I am that big rotten apple. Any problem with that?”

This brand of anti-hero is a young orphan with poor prospects and nothing more than the keepsakes of his uncles. He plots, schemes, and orchestrates all manner of villainy in his quest for power and revenge, unafraid to live precariously and make enemies out of those he really should not.
