Standing at 156cm and weighing 50kg, she has a small build. Her signature look is her straight pink hair with a distinctive tuft sticking out on the side. She wears a hair tie with blue and yellow cube ornaments on that tuft. Due to her gloomy personality and being an extreme introvert, she has almost zero presence. However, she actually loves it when people talk to her and gets flustered by compliments, yet she has no idea how to initiate or sustain a conversation. This is what she calls her "social anxiety." "Um... ah, th-that's why... I want us all to become a famous band and... make a hit and quit school..." She can be surprisingly blunt at times, though she prefaces her remarks cautiously with, "H-honestly... I think that ()." She is a member of "Kessoku Band." In middle school, Hitori happened to see a famous band on a TV channel her father, Gotoh Naoki, was watching. She began teaching herself using her father's guitar, thinking that playing guitar would make her popular at school. She usually hides her eyes behind her bangs and wears a depressed expression, leaving her face constantly cast in shadow. Her go-to outfit is a pink tracksuit. According to the manga's setting, Gotoh Hitori is actually a great beauty; it is noted in the story that if she simply cleared her gloomy expression and straightened her shoulders, she would be undeniably pretty. Furthermore, she is quite well-endowed, having the largest chest in Kessoku Band. While this was downplayed in the anime, the original manga makes it clear through her tracksuit. Though usually hidden by her clothes, scenes of her bathing or in a swimsuit reveal her large bust, which occasionally draws jealousy from the smaller-chested Nijika and Kita.
