A man who was once called the world strongest agent ended up becoming a teacher after his retirement to train the new generation of agents. After many years of training his disciples, he is killed at the age of 60 by the ploy of a secret organization and was reincarnated in another world with all his past memories.Though he was surprised by the magic and the strange species of that world, he adapted very fast to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his tight discipline in order to reach his goal: resume his career as a teacher which he left halfway through in his previous life.This is the story of a man who based on the memories and the experiences of his previous life, became a teacher who travels through the world with his new students.

A former sporting rifle shooter genius transforms into the ‘Juvenile Butcher’. While originally supposed to have received the death penalty, he was instead fortunate enough to have entered a secret and highly regarded armed force, throwing himself into the ‘Nirvana Project’.

Amid a world war, with his awakening to powerful special abilities (Soul Armor Abilities), Kamiya Yuusuke, conscripted into the military at the age of 10 due to this newfound power, continued to achieve numerous victories on the challenging battlefield. As a result, at the age of 15, he held the position of Brigadier General.Despite traversing battlefields worldwide, he finally managed to return to Japan. The joy of returning home was short-lived, as news of an underage boy in the military started to leak to the public. In response, the military high command ordered Yuusuke to attend a military school called the Special Operations Soul Armor Academy and undergo a revision of his military records.Yuusuke, secretly pleased at the prospect of reclaiming his youth, faced numerous troubles, whether due to the nature of the unique school or perhaps because he had been in constant battle since childhood. What will happen to his relationships with strong-willed girls such as his half-silver-haired childhood friend, the older sister officer who is his work partner, and the tsundere honor student of the same age?

Existence was divided into three realms. The Heavenly Realm. The Earthen Realm. The Infernal Realm. Below them, countless minor realms of all types existed, none able to match the might of any of the Three Fundamental realms. The Celestials led the Heavenly Realm, The Immortals led the Earthen Realm and Demons led the Infernal Realm while the Rulers controlled all the minor realms. Together, they formed The Myriad Unity and allowed peace to reign supreme. The mortals were allowed to cultivate and reach for the Heavens as a balance was installed between the Heaven and Earth, all according to the Heaven’s Will. And yet, among the billions of trillions of living beings within the Myriad Unity, one seemed unsatisfied. “They are lying to us.” This man went against all known truths and contradicted the very gods. “We are in a false world! Mere pawns used to study an outcome!” And so in search of freedom and truth, this man committed the ultimate taboo. He rebelled.
