A first-year student and the leader of the Dragon Girl Student Council at Sakuryu High School. She is in the same class as Mega, Gyai, Suzu, and Zeos. Despite her position, she has a 'tofu heart'—fragile, cowardly, and easily intimidated. She longs for a glamorous, sparkling lifestyle. First person: I (polite/feminine). She addresses Mega, Gyai, Suzu, and Akira with '-chan', Zeos with '-san', and everyone else with '-san'. She generally speaks in polite Japanese (keigo).

An extreme airhead and a total space cadet. Her actions are completely unpredictable and off-the-wall. She moves at her own pace, often dragging those around her into trouble, though she remains blissfully unaware of the chaos she causes. She is the most eccentric member of the five council members, often leaving Gyai's retorts in the dust. However, she actually thinks more deeply than she lets on. First person: I (soft/boyish). She calls Arshu 'Prez', Gyai just 'Gyai', Suzu 'Suzupoyo', and Zeos 'Zeochi'. For friends outside the council, she uses various nicknames ending in '-chan', '-chi', or '-poyo'.

She attended the same elementary school as Mega. She moved to the Kansai region due to her parents' work and returned with a thick Kansai accent. Because the other four council members are so eccentric, she usually plays the 'straight man' (tsukkomi) and is the most sensible person in the group. She acts as the balancer who keeps the five of them together. First person: I (regional/casual). She calls Arshu 'Arshu-han', Mega and Suzu by their names, and Zeos 'Sis'. For those outside the council, she uses bare names, 'Senpai', or the '-han' suffix like she does for Arshu.

The youngest member of the council and its resident trickster. While she looks like a selfish child, she is a genius with a sharp, logical mind and a silver tongue. She usually acts spoiled and demanding, but occasionally says something that hits the nail on the head. Her blunt truths can sometimes hurt others. She is secretly self-conscious about her childish physique and harbors a hidden jealousy toward Zeos. First person: I (archaic/regal). She calls Arshu 'Prez' and Mega by her name (or 'Airhead'). She calls Gyai 'Chifuuin' and Zeos by her name (or 'Lunkhead'). She occasionally addresses the council members as 'you' (rude) or 'you lot'. For others, she uses surnames or 'you' (rude).

An international exchange student. Having been taught strange Japanese, her first person pronoun is 'We' (imperial). Back home, she had a bit of a short fuse... a trait she tries to hide now. However, her original aggressive nature and 'big sister' vibes leak out, and the council members have already caught on. She is big-hearted, composed, and acts as the group's guardian. She often speaks with a motherly tone. In crucial moments, she sometimes messes up her words of encouragement. She generally addresses everyone with '-chan', though she uses 'Senpai' or '-san' for certain people.

Dora Godai: The ace of the Karate Club who has won numerous tournaments since childhood. She has never lost in karate. She has a wild, reckless personality and is full of curiosity. Initially, she believed winning was everything, leading to a rivalry between the Aoharu Group and the Student Council, but since the Freshman Mixer, she has been practicing how to be a friend. First person: I (old-fashioned/rough). She addresses others as 'thou' or 'ye' depending on the situation, but occasionally uses names. Shinobu Aozaki: A member of the Swimming Club who speaks with a Hakata accent. She is stoic and never neglects her training, possessing enough skill to compete at the prefectural level. Having devoted her life to her club and moving frequently, she struggled to make friends. However, since the silent Infinity became her friend, she admires them blindly. First person: I (regional/casual). She generally uses '-chan' for everyone and '-senpai' for upperclassmen. Jurako Lieuber: A returnee socialite who occasionally mixes English into her speech. Due to her busy parents, she moved across borders dozens of times. Since childhood, 'tennis was her friend' until she met Maron at a homestay and moved to Japan for high school. She is a bit sheltered. While she appreciates Maron for always being there, she secretly thinks she is the cutest. Maron Sukune: A member of the Art Club with a unique way of speaking and laughing. Often treated as an outcast in Japan, she had a lonely childhood. For a long time, 'painting was her friend' until she met Jurako at an overseas homestay and made her first friend. She has a strong artistic sense and constantly strives for higher art. She is best friends with Jurako. First person: I (formal/eccentric), ending sentences with '-deshi'. Teiozaka Infinity: A member of the Game Club who basically doesn't speak. They use text-to-speech for simple communication. Shinobu sometimes acts as their interpreter. Their gaming skills are world-class, having won an FPS world championship. To focus on the game, they generally refuse voice chat.

Akira Anno: The guitarist and vocalist of Jack-pot. She is shy and dislikes standing out. Admiring her sister Shuura's band, she secretly started activities as a 'faceless' online singer. Shuura found out and forced her into Jack-pot. Though reluctant at first, she is now very motivated. Shuura Anno: Akira's older sister and the keyboardist/vocalist of Jack-pot. She is a social butterfly and kind, often helping the other members. However, she has a terrifying side when angry. Eiku Harusaki: The guitarist of Jack-pot. He is a man of few words who occasionally drops sharp retorts. His private life is a mystery that even the members know nothing about. Feruki (Masaki Hoshi): The drummer of Jack-pot. He has been childhood friends with Zana since elementary school, and they promised to form a band back then. He has known the Anno sisters since middle school. He loves cute things. First person: I (casual/masculine). Ludo Zana: The leader and bassist of Jack-pot. He possesses overwhelming charisma and leadership. He is multiracial but was born and raised in Japan. Despite his unique worldview, his choice of words is highly praised for being pleasant to the ear. He often makes remarks using 'sparkly' unconventional names.
