Golden Stage - Chapter 5: Plot

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.

It has been more than ten years since he was transported to another world. The protagonist Deris Fahrenheit, who has became a magician with special circumstances, was freely enjoying his life in this world. However, a girl appeared before him and asked him to make her his disciple. That girl seems to be a transported person――

It’s a story of him who becomes the girl’s teacher and trains her to achieve her revenge (?) in otherworld.

The world has become a playground for the world of the heavens, and all living beings are digitized, waiting for the players in the world of the heavens to come to kill and torture countless times.

Yi Zheng, who turned into the first trash rabbit in Novice Village, chose to take a group of rabbits to start running, sit-ups, bench presses, rowing, swimming on the green grassland…

A year later, when the player came, what they saw was not a group of mobs, but a terrifying devil muscle rabbit!

The Rabbit King, who was sitting high, waved a carrot and said cruel words: “Starting today, don’t even think of leaving the Novice Village alone!”
