First Assistant's Petite Wife Has Space - Chapter 15

I possessed the weakest character in my favorite game’s Hell Mode. I want to survive, but the way the main character is being controlled is atrocious.

It can’t be helped.

I have to stop the bad ending myself.

Someone palmed out a blue dragon, which shocked the world. Someone smashes the green hill with a fist, and thousands of people admire it.

Some people live for thousands of years, just like gods. Some people are merciful and compassionate to the world.

In this world of panic, how can there be no place for me?

(The protagonist kills decisively. If you are not a virgin, kill if you have the strength, and if you don’t have the strength, you will die.)

- Description from novelbuddy

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.
