I was working hard as a teacher in poor eiviroment and was reborn as a villainous nobleman, Lacoya Terracotta, in an open-world RPG. I was reincarnated after various events had already taken place and I was doomed. Lacoya is a mob character who does not appear in the main storyline from this point on. Lacoya is a person who has been given many flags for the convenience of the developers. As one of them, he was given a hidden status buff that increased the “growth speed” of his surroundings in order to accelerate the early stages of the game. The children who learn magic under Laquoya’s instruction master it at an unbelievably fast pace, and eventually the rumors reach the main characters of the game.
