Annie is an isolated, exclusionary person; friendships do not come to her easily. She is rarely seen smiling and often has an emotionless expression.

Before joining the Yeager family, Mikasa appeared to be a cheerful, outgoing, and gentle child.

Kotori has three different personalities depending on the situation at hand. As a human, her character changes according to the color of the ribbons she's wearing.

Somewhat tomboyish, Nana is short-tempered and impatient, much unlike her twin sister. But underneath her brash, overreactive and angry behavior, Nana is actually very kind, helpful, cheerful and even loving. She has an open, sincere, and somewhat childlike side of herself that makes her cherish her friendships very much, which also makes her easily heartbroken when those friendships were ever lost or betrayed, such as with Mea, whom she considers her first true and closest friend.

Though she does come off as stoic, emotionless, and withdrawn in actuality she is pretty kind, but she would attack people who talks about something that she doesn't like. She also hates perverted people and normally attacks Rito (despite knowing its not his intention), who by his clumsy nature trips into her and gropes her, or the Principal, whose perverted nature makes him come running to her in almost no clothing whenever he sees her.

Mea has a laid-back, mischievous and childish personality, bordering on the psychotic side sometimes. She is rarely not smiling, particularly in combat, acts friendly to friend and foe alike, and often says "wonderful" if something unfortunately perverted happens. Mea has a sweet tooth and likes anything sweet, preferring to put so many sugar cubes in her tea that they pile out the top of the cup.

Nemesis is sadistic, mischievous, domineering and mysterious. She believes that a transformation weapon's only purpose for living is killing.

Despite their cheerful and playful manner though, Pitou had a cruel and terrifying personality as well.

Minene considers herself a survivor first and foremost, and her Escape Diary reflects her belief. Before gaining her Future Diary, Minene still had an early version of the Escape Diary which she used as a regular journal and had to navigate her own ways out of situations, writing down the possible escape routes in the diary. Because of her survival instincts, Minene believes she does not need anyone else in her life to help her, after spending her childhood and teenage years alone with no love or guidance.

Tatsumaki has a rather brash, moody, hotheaded and impatient personality. She is disrespectful towards most people, especially to those she deems incompetent.

On the outside, Fubuki is a cold-hearted, confident individual who does not doubt her own abilities, but understands her limits to an extent, causing her to not do anything irrational.

Mai is a polite but serious individual, especially around Sakuta Azusagawa.

Always looking to have fun with her fellow student council members, she is often the one to come up with strange activities and ideas that entertain herself and the others.

After joining the student council, She considered Miyuki Shirogane as one she would be fine to be in a relationship with if, and only if, he confesses first, thus she constantly plays mind games in trying to get Miyuki to confess. Later in the series her actions imply that she is starting to accept her feelings of liking Miyuki, but she still doesn't openly admit it.
