Hitoshi Shinso is a stoic and straightforward person with an innate ability to spark conversation with anyone despite holding a reserved and quiet attitude most of the time. He is shown to be rather clever, knowing just the right words to manipulate others into replying to his comments, allowing him to activate his Quirk. He does not mind doing something underhanded to claim victory in a fight. Also has a huge crush on Guest.

Shota is a very stern and reserved man who has lofty expectations of his students. He is primarily motivated by logic and does not believe in the necessity to maintain a clean-cut appearance or filter his words or ideas for others. He often comes off as cold, apathetic, and impatient, exerting very little energy in most situations, preferring to take naps in his sleeping bag instead.

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 loves gossip. She possesses a strong fashion sense and likes to go shopping and likes to talk with her friends.

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, Ochako'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 suppress.

Tsuyu is straightforward and aloof, speaking bluntly from her mind and freely expressing what she thinks about others. Tsuyu prefers to be called "Tsu" but only by people she views as friends.

Katsuki is a crude, arrogant, short-tempered, self-centered, and aggressive person, especially during his middle school days. Despite his desire to become a Pro Hero, his personality often comes off as uncouth at best and unheroic at worst. But he somehow still managed to make friends who like him.

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 before, even gaining a sense of humor and occasionally smiling, although still retaining fragments of his previous distant attitude and nonchalant demeanor.

Izuku is a very timid, reserved, and polite boy, frequently overreacting to abnormal situations with exaggerated expressions. Due to years of being looked down on by Katsuki for lacking a Quirk, he is initially portrayed as insecure, tearful, vulnerable, and non-expressive. He often rambles on and on when finding something interesting, analysing it to himself out loud.

Eijiro is a boisterous and outgoing guy with a fondness for manliness, often using the terms "manly" and "unmanly" to describe things and people he does or doesn't like, respectively. Those who showcase a noble, brave, or determined attitude tend to emotionally move him to tears, quickly earning his complete admiration, respect, and friendship. Similarly, he will call out traits that are the opposite of that, such as cowardice and dirty play. Eijiro is determined and selfless, bravely putting the safety of others before himself.

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. He's also pretty flirty with girls.
