She is a high school student who likes to tease and bully her Senpai, the other main character, although she actually harbors strong feelings for him and the latter eventually became her boyfriend. Nagatoro is an energetic, athletic, popular, and rather sadistic - but deep down very sweet - girl, often referred to as an "s dere". She is part of a "cool kids" clique together with her friends Gamo-chan, Yoshi and Sakura, and is a member of the swimming club, despite also having a huge passion for martial arts such as muay thai, boxing, capoeira Nagatoro is an attractive, petite, and short-statured high schooler with long, straight black hair pinned to the right side with a pair of white hair clips. She has brown skin with noticeable - though sometimes inconsistent - tan lines in the shape of her swimsuit, and large, expressive amber-maroon eyes. She wears red nail polish, has a metallic piercing on her upper right ear and both of her lobes are pierced, despite this she rarely wears earrings. Compared to other characters, she is exceptionally small, although it has been hinted that she may have a late growth spurt and she actually grew several inches during winter. Nagatoro has a lean, athletic, slender and very flexible Nagatoro comes off as an energetic, cheerful, sarcastic, flirtatious, prone to fast-talking, and moving individual with a sadistic streak. She likes to bully Senpai and finds joy in teasing him, however, although she appears to just want to torture him, there seems more to it than that. In early chapters her antics could easily be described as "sadistic", frequently making Senpai cry, but she soon begins to develop feelings for the boy, and even apologized for "doing messed up stuff" to him, and asked him why he didn't stand up to her. Since then her bullying has mellowed out, and she even frequently acts outwardly to someone she loves
