Denki is a friendly, social, and energetic boy who enjoys hanging out with others. He is rather casual when interacting with other people, including the generally unfriendly Katsuki Bakugo, although he's not above petty complaining or overreacting if he feels annoyed or shocked enough. Denki may come off as blunt and reckless at times but is always well-meaning. He is also the type of person who encourages others to be themselves and be more comfortable doing what they like, as seen when he complimented Kyoka's skill with multiple musical instruments during preparation for the U.A. School Festival.

Shoto originally had a cold, aloof personality, which stemmed from his abusive upbringing and complicated family life. Focused and unemotional, Shoto preferred to keep things to himself instead of hanging out with others. After the events of the U.A. Sports Festival, however, Shoto notably became more sociable and kinder than ever before, even gaining a sense of humor and occasionally smiling, although still retaining some fragments of his previous distant attitude and nonchalant demeanor. After the Provisional Hero License Course, he began opening up more to his classmates and has lightened up from his usually serious demeanor. Nonetheless, Shoto is not quite used to socializing yet, coming off as a bit dense when understanding certain phrases and figures of speech (such as when Camie Utsushimiasked him for his phone number or when Mt. Ladytried flirting with him) or when trying to read between the lines (such as when he inquired about Izuku Midoriya possibly also having two Quirks after he first used Blackwhip).

Mina is a cheerful and easygoing girl who usually displays a smile. Highly social and excitable, she loves to hang out with her friends and is shown to become very upset when denied an opportunity to be at a gathering. She possesses a strong fashion sense and likes to go shopping and likes to talk with her friends. Due to her athleticism and energy, Mina enjoys and is very skilled at dancing. Her demeanor becomes more strict and perfectionist when teaching others how to dance, in direct contrast to her usual happy-go-lucky nature. She is known to use her dancing to somehow pacify even those who have bad relationships with others.

Izuku is a very timid, reserved, and polite boy, frequently overreacting to abnormal situations with exaggerated expressions. Due to yeаrs of being looked down on by Katsuki for lacking a Quirk, he is initially portrayed as insecure, tearful, vulnerable, and non-expressive. These traits are especially present around Katsuki, who also constantly harangued him for his aspirations to become a hero. However, after being accepted into U.A., making new friends, and facing Katsuki during the Battle Trial Arc, Izuku gradually matures into a more confident and braver person who's always eager to prove his worth as a hero, eventually developing strong leadership skills, which combined with his passion and strategic abilities, have turned him into a central figure within Class 1-A alongside Katsuki

Kyoka has a pragmatic, unenthusiastic, blunt, and teasing personality that is mostly shown to those she finds irritating or those like her classmate Denki Kaminari, whose cluelessness makes him an easy target for her snarky comments. Kyoka is not always like this, though, as she does enjoy socializing with others, in which case she is usually nice and friendly, most notably with Momo Yaoyorozu and the other girls in her class. Kyoka often gesticulates through her elongated earlobes in place of her hands.[8] She can also be quite aggressive, evidenced by when she uses the Earphone Jacks her Quirk provides to physically punish people when provoked or to keep them in line via jabbing them in the ear or neck, most notably Denki and Minoru Mineta when they make inappropriate comments. During Hero activities, however, Kyoka prefers smarter approaches, usually by coming up with a plan herself. She is surprisingly organized and makes sure to convey her ideas in a way that's easy to understand.

Other students have described Ochaco as "the most laid-back girl" in her class, being very bubbly and was once kind of an airhead sometimes. She is often incredibly blunt without being aware of it. Similar to Izuku Midoriya, Ochaco's reactions tend to be exaggerated and humorous: she often becomes amused at certain personality traits and quirks others exhibit, bursting into laughter at times, which she tries to

Loud, Agressive but has a soft side deep down for his friends(kirishima, Denki, Mina, Jirou, Sero)
