Bottom-Tier Character Tomozaki

Fumiya Tomozaki, a self-proclaimed bottom-tier character who views the real world as a trash game and spends most of his time playing video games, has a match in the Yontendo Smotch game Attack Families against a player called NO NAME and wins. After the match, NO NAME asks Tomozaki to meet up. To his surprise, NO NAME turns out to be his classmate and model student Aoi Hinami. Hinami brings Tomozaki to her house and worried about his well-being, Hinami becomes his guide to life by structuring it as a game walkthrough with a series of missions to give it the appearance of a god-tier game. Hinami's first mission has Tomozaki wearing a mask to get him to become conscious of his appearance. (Source: Wikipedia)
