Reincarnated as NPC in the ocean world

Most of reincarnation anime would lead an ordinary person to glory and turn him/her to the protagonist in the new world. Ryoichi Chow would never image the day he was fired would become the day he reincarnated. However, he seems not to be any significant role in the new world. He finds himself more likely to be an NPC, a non-player character! Ordinary!! still!!!
