Anime world of Hoshi: Multiverse Guild Master Sorata.

Sorata Kanda was a bitter loser who spent his entire life blaming others for being much stronger or more talented than him. Losing in terms of looks, build, intelligence, and goals he wanted to work hard for in his life created a life in which he even dragged a genius girl like Mashiro to his level in the end. One of his biggest mistakes cost him the enmity of many people in both his world and the worlds in which he was being viewed as an anime. Therefore, a judgment was rendered after he had passed away and returned to the world of spirits, where the king of Yama questioned him about his satisfaction with the choice he had made. As a result, a new soul was introduced in his place and sent back to the moment he was dispatched to Sakura Dormitory, where the main plot of the story began.
