Bottom-tier Character Tomozaki(2017)

Despite being number one in the game “Tackfam”, Fumiya Tomozaki struggles in high school due to a lack of social skills. Fumiya was surprised to learn the identity of the number two “Tackfam” player after a fateful encounter—a popular, clever, and outgoing female classmate of his, Aoi Hinami. Aoi was taken aback to learn that the inept Fumiya was behind the username "nanashi," and she became determined to assist him in winning the "greatest game of all." With Aoi's help, Fumiya begins to progress in the wonderful "game of life" by overcoming the harsh challenges of social interaction and human relationships.
