Gekitotsu no Hexennacht - Volume 2, Chapter 9: It Isn’t Enough

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.

Thank you for making me think I once loved you. Now, never see me again, even in death.”Just as she turned to leave in triumph, she accidentally walked into a gang's arms deal, and an explosion forever separated her from him.It was only when he found the two-month pregnancy test result among her belongings that he realized he had lost the only salvation of his life.
