Inui Sadaharu (乾貞治(いぬいさだはる)) is a 3rd year student at Seishun Academy Middle School, regular and manager of the tennis team and member of the Japanese U-17 medical team. He is the childhood friend of Yanagi Renji and a Data Tennis player.


Inui's most prominent feature are his thick, black frame square glasses that conceal his brown (manga)/green (anime) eyes during the entire series. He has spiky black hair and is frequently seen carrying a green notebook where he records his data. When he is not a regular of the team, he is depicted wearing green sweatpants and a white T-shirt. When he is a regular, he is seen wearing his Seigaku kit, with the school-branded sweatpants and the jacket zipped up to just below his neck. As a member of the U-17 Camp's Black Jersey Brigade, he is depicted wearing the black version of the team jacket and white shorts. Inui is typically depicted with a neutral expression, but has a sinister smile when he brings out his various "Inui Juices" to torment his teammates.



Prior to the events of the main story

Inui meets a young Yanagi Renji at a tennis school, where the two pair up to become a doubles team. Yanagi teaches him about Data Tennis and the two are said to be one of the leading doubles teams in the junior tennis world.[1] Realizing that they had never played a game against each other, the two decide to play a best-of-one set. The game reaches 5-4 in Yanagi's favour before they are kicked off the court by their coach.[2] While running away, Inui promises Yanagi to continue the match at an upcoming tennis tournament they were scheduled to play in, but he never shows up on account of moving away.
