The man once called the world's strongest agent became an educator training the next generation upon his retirement. After raising disciples and passing sixty years of age, he dies in an operation orchestrated by those in power above him, but is reborn into another world while retaining his memories. Though surprised by different races and magic, he adapts with his characteristic quick thinking, turning everything into his own sustenance. As he masters special magic and continues rigorous training, he reaches the strongest level of power, but decides to pursue the path of educator once more—something he left unfinished in his previous life. This is the story of an educator who, based on the memories and experiences of his former life, travels the world together with his disciples.
