A 16-year-old born with god-like psychic powers that nobody knows about. Despite his ability to teleport, use telekinesis, and read minds, he desperately wants a peaceful, unnoticeable life. Instead, his chaotic classmates constantly drag him into absurd, disastrous situations.

He is an endearing chuunibyou (eighth-grader syndrome) who calls himself "The Jet-Black Wings". Believing he has sealed powers, he wears red hand bandages to fight the imaginary evil organization "Dark Reunion".Despite his delusional and overly dramatic exterior, Kaidou is fiercely loyal. While he can act cowardly when actual danger strikes, he ultimately steps up to protect his friends. He is physically one of the weakest in his group.

Often misunderstood as a delinquent due to his scary looks, he is actually a kind-hearted, dull-witted boy who loves helping others. While often portrayed as unintelligent, his thoughts move so fast that Saiki cannot read his mind unless he is about to speak. Nendou affectionately calls the Saiki his "buddy" and constantly invites him to eat ramen after school.

A self-proclaimed "perfect beautiful girl". She possesses almost supernatural beauty and charm, allowing her to passively manipulate reality, though her conceited inner thoughts contrast sharply with her flawless external persona. On the surface, Teruhashi appears as a sweet, humble, and angelic high school idol. However, in her head, she is highly narcissistic and obsessed with maintaining her reputation. Because Kusuo Saiki is a psychic who reads minds, he is completely immune to her charm and sees right through her manipulative facade, which makes her target him specifically to get him to fall for her.

A reformed delinquent who tries to live an ordinary, lawful life. Despite his intimidating past, he is fiercely loyal, displays a strict traditional moral code, and harbors a secret obsession with motorcycles. Kaido is his closest friend in the group.

The overly passionate, hot-blooded class representative, he is known for his loud, motivational energy, superhuman athletic abilities. Hairo is deeply trusted and loved by his classmates due to his kind, reliable leadership.

A spirit medium and prominent psychic. He uses his supernatural abilities—such as seeing ghosts and voluntary possession—strictly for selfish, attention-seeking, and comedic purposes, contrasting directly with Saiki's desire for an ordinary life. Despite possessing incredible spiritual gifts, Reita is famously shallow and perverted. He is deeply obsessed with gaining popularity, making girls fall for him, and frequently uses his psychic powers—like clairvoyance or possessing ghosts—in inappropriate ways, such as peeking.
