A brief description of the manga Tensei Goblin da kedo Shitsumon aru?
An ordinary office worker should have died in a traffic accident, but when he awoke he became a goblin. Goblins have a lifespan of only seven days. However, the hero who has been given the skill “Human 80 years” takes advantage of his longevity and takes over the skills of many goblins and even the demon king who is on the verge of destined life, and stands out in a different world.
