It Seems That I've Slipped Into a Different World. Also, My Gender Has Changed. - Chapter 47: Welcome Home and Night Chat in My Room

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.

There was a prominent old martial arts family which in the hundred years would give birth only to males, never a girl. Finally, one day, a girl was born. She was a tassel blower among ten thousand green groves. Ultimately, she turned into an agile and brave tomboy!

There was also an imperial descendant who his old father had six princesses. His father was just short of a son to inherit the throne. Finally, one day, he got a bastard son who was his youngest child. With countless spoiling, in the end that son was brought up into a universally unmatched egomania!

“Zhen as the nation’s number one beauty, as the nation only first class figure, obviously needs to have a professional bodyguard constantly at our side for protection. That will be you, the iron-willed female King Kong pretending to be a little eunuch.”
