He was a 3rd year middle school student at the beginning of the series, he graduated later on. A suave, but shallow playboy, Nanjou took an interest in Yamada Anna for her looks and social status. He served as a recurring antagonist for Ichikawa Kyoutarou.
Personality.
Forceful and persistent, Nanjou is drawn to attractive women. He attempts to use pickup-lines and compliments to get their attention, to mixed success. He doesn't tend to take hints well when he is annoying people, and only backs down when expressly told "no." He is good at manipulating the flow of conversation to get the topic back to where he wants it. He is willing to use small amounts of force to get his way, such as when he grabbed Yamada's arm to intimidate her into giving her LINE account to him. That said, he appears willing to help people if the situation calls for it, such as aiding in fishing out Ichikawa's bike from the river when he throws it.
Trivia.
He was in the soccer club, but stopped playing due to an injury and his belief that he couldn't succeed at it.[source]https://bokuyaba.fandom.com/wiki/Nanjou_Haruya[/source]
