Kazuomi Ooga looks like a flashy student, but he has the best grades among the boys in his class. He has a pure side and is not interested in romance. He is not athletic.
SpoilerKazuomi greatly respects his older brother, who had previously shouldered the responsibilities of providing for the family. Even after Takaomi became a NEET, Kazuomi simply felt it is now his old turn to be responsible and let his brother time to rest. The piercing Kazuomi got from his brother was one of his greatest treasures, as a remembrance for when Takaomi was cheerfully working hard.
