He asked for the name of an anime.
The male protagonist thought that he was a hero from another world, so he had four personalities. One was the hero, and two were the hero's companions. One of the companions worked in a tea restaurant, and the other liked to wander on the streets and was very good at fighting. The last personality seemed to be the Demon King. Under the Demon King's personality, he was still acquainted with the boss of the local society. However, because the Demon King's personality was too domineering and wanted to destroy the other personalities and even the main personality, the protagonist's sister's affectionate expression moved the Demon King's personality, so the Demon King's personality decided to disappear. In the end, it seemed that the protagonist's childhood sweetheart was jealous and felt that the protagonist was living too freely. The friendship broke his face and punched the protagonist awake. In the end, the protagonist found that his two companions were gone, leaving only the letters and money they left behind.
