Kinoshita has short, spiky light brown hair and large narrowed eyes. He is average in height and is the shortest second year apart from Nishinoya.
He's very anxious when it comes to his own abilities and constantly worries about whether he’s good or not. Even though he isn’t a regular, he is very supportive of his team. He's also been noted to have an "uncanny knack of putting points on the board" by Ukai. He's always seen cheering Karasuno on. It seems he's not afraid to make sly remarks about his teammates such as telling Tanaka, "Don't take off your shirt, baldy!"
In his first year, he joined Karasuno boys' volleyball team, which had been more of a recreational club than a team at that time. However, Coach Ukai returned from retirement shortly after and restarted training. Unable to keep up with it, Kinoshita left the volleyball team, along with Ennoshita and Narita, for a while. By the time they realized how much volleyball meant to them and decided to return, Coach Ukai was already gone again. Regretting their decision, they started to call themselves the "Ungrateful Second Years".
