In this new world, Asato discovers that he can gain powerful abilities through a system of levels and skills, similar to a video game. He quickly becomes overpowered, acquiring cheat-level abilities that make him nearly invincible. These newfound powers, however, not only change his life in the fantasy world but also begin to transform his status in the real world. Asato goes from being a ridiculed outcast to someone who commands respect and admiration.
