Nijimura was the captain of Teiko Junior High, leading the Generation of Miracles when they were in their first year.
He has short black hair with his bangs parted to the left and has light grey eyes. He is of average height and wears a black armband on his left forearm. Being the captain, he played with the jersey number 4, but after he recommended Akashi as captain,he played with the jersey number 9.
PersonalityNijimura is a calm and collected individual, but a severe upperclassman who is not afraid to speak his mind. He didn't hesitate to beat up Haizaki when he suspected the latter to skip matches. He also possesses a sharp mind: he could tell the changing atmosphere due to the arrival of Kuroko or that one day, Nijimura himself will be surpassed by the Generation of Miracles. Being the former captain of the Teiko first string, Nijimura is a leader and is easily listened to.
However, he criticized himself about his hotheadedness that can impinge with his judgement as a captain. Nijimura has also a caring side, as he claimed that he would stop playing basketball right away to visit his hospitalized father if something happened to him.
Back in junior high school, Nijimura had the reputation of the strongest power forward in the league. Being the captain of Teikō Junior High, he had certainly proven himself to be an excellent player all-round. As the power forward, Nijimura has a very fast and strong drive. Reaching all the way inside to the basket, he is also seen switching to a pass lightning fast and swinging it to the free man. His drives are really powerful and effective enough to easily drive through anyone. However, his skills are eventually overshadowed by the Generation of Miracles' dominance.
