- Description from novelupdates

I, a mere con artist, was unjustly imprisoned in Tantalus, the Abyssal Prison meant for the most nefarious of criminals, where I met a regressor.

But when I used my ability to read her mind, I found out that I was fated to die in a year…

and that the world would end 10 years later.

A man who was once called the world’s strongest agent ended up becoming a teacher after his retirement, to train a new generation of agents. After many years of training his disciples, he was killed at the age of 60 by a secret organization’s ruse and was reincarnated in another world with his memories intact. Though he was surprised by the existence of magic and the strange species in that world, he quickly adapted 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 rigorous 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 students.
