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.

Dilan, 21-years-old, was anything but ordinary. He sought adrenaline wherever he could.

Life didn’t feel worth living on the small blue planet he was born on.

However, it was a seemingly ordinary night on new year’s eve that everything changed!

A raging storm manifested on the mountainside he had climbed on to feel free, to escape the ordinary world that bored him to death.

And death was what awaited him eagerly as he was flung through the air, just to be pricked by an old, seemingly ancient tree trunk.

Not even a miracle would be enough to save him anymore.

But it was just at this moment that something much bigger than a miracle happened.

Every single existence on the blue planet got connected to the Log of the Ancient, something most would label as “Status”.

The ordinary and mundane world changed forever, turning into a bloody and merciless battlefield as the Primordial Ascension unsealed the shackles that weighed on the planet for millions of years.

Mythical mana was unleashed, animals began to mutate, zombies emerged, and monsters known from fairy tales appeared out of Gates.

Follow the journey of a man, who seeks adrenaline, who embraces pain, who overcomes death itself …a man, who will become an Undying existence!

Soul Piercing Konoha, born as a civilian, will go to the battlefield of the Third Ninja World War tomorrow.

Just graduated from “Ninja School”, Yangtai, who only knows three body techniques and a D-level hemostasis technique, looked at the full of energy, and finally made up his mind – “The battlefield is too dangerous, I’d better go to other worlds to hide. !”
