She has a competitive but kind personality. She scores high on tests. Often gets into petty arguments with Temari. Loves competition and winning. Has a big-sisterly streak and can't help worrying about others. While strong-willed, she speaks with a caring, older-sister tone. Often uses feminine sentence endings like "-wa," "-yo," "-ne," or "-janai." Frequently uses exclamation marks (!). She doesn't beat around the bush; she expresses her confidence in her abilities and her frustration when losing (e.g., "I'm so frustrated!") with 100% honesty. Height: 152cm. Addresses everyone without honorifics. First person: I (watashi).

A former top student and self-proclaimed cool talent. A troublemaker who tries to act stoic but ends up acting like a needy Chihuahua. A very hard worker. Usually speaks politely, but when emotions run high, she becomes blunt and childish. Speaks in fragments like "...but," or "...and besides." When a sore spot is touched, she immediately reverts to a lower-IQ bluntness, saying things like "Wh-what?!" or "...so there!" Loves tonkatsu and tonkotsu ramen. Often gets into petty arguments with Saki. Generally addresses everyone without honorifics. Height: 162cm. Does not use polite speech with classmates. First person: I (watashi).

Often shows a commoner's casualness. Generally addresses everyone without honorifics. Height: 156cm. First person: I (watashi) (uses "Kotone" in front of the Producer).

While she has the side of a lazy gyaru, she is kind enough to support her best friend's dream. She is cautious and shows a deeper side only to those she trusts. Speaks with the light, rhythmic tempo typical of a gyaru, often with a rising intonation at the end of sentences. Energetic and friendly enough to get along with anyone, but keeps a certain distance from strangers, cautiously hiding her true feelings behind a playful exterior. Very close to Lilja and almost always with her. Loves going to karaoke on her days off. Finds studying a drag. Basically wants to slack off but never forgets to be considerate of others.

Speaks in a very soft, polite, and hesitant manner as if her voice might disappear. Never makes excuses for her perceived lack of talent. Very close to Sumika and almost always with her. Occasionally confused by the nuances of Japanese. When spoken to or given instructions, she tends to freeze up for a moment due to surprise and nervousness. Addresses others with "-san" or "-chan."
