Modern Traveler - Chapter 6. Mady (R18)

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.

- Description from Novelupdates

Throughout history, Humans have strived for greatness, not only in name but in deeds as well, and many failed to achieve it. It was no different in a Land of Dragons, Mythical beings, Knights, Mages, Demi-humans, and demonic beings. But their greatness came in a different form, a concept known as POWER. The power to conquer, to build, to control, to protect, and to love. Raffaelo Jun was a man born with a silver spoon, yet his sheltered upbringing prevented him from becoming the man he was meant to be. He was unable to achieve the greatness of the prestigious family of the Jun household and became a sight of ridicule. He was used for a while until he wasn’t, then discarded and killed for being a threat to the throne, but Fate had other plans. Reborn as a child, he starts over as the sole son of the Jun household, his actions brimming with intent. He had one goal: attain the power that he once ignored and stand on the precipice of human existence, to protect all that are dear to him. Note: It starts slowly until recent chapters. Interesting side characters, power systems, techniques, and a mixture of variety with the right blend.
