Beginner Class. A boy full of positivity and passion. He is so confident that he takes insults as compliments. Thanks to his burning passion, he is highly competitive and clings tenaciously to even small matches. He is loud and tends to meddle in everything. His habit of interfering extends from his friends' business to the affairs of total strangers. Deep down, he believes there are no truly bad people in the world. Being eccentric and full of curiosity, he lives with accidents and incidents every day. Male. Appearance: Brown hair, brown eyes. Spirits: Leecheon-sungi, Ppeon-doyaji Ghost Rider: White Whale King

Advanced Class. The ace of the Ghost Ball Academy, she is popular among male students for her beauty and academic excellence. Furthermore, she is loved by female students for her tsundere personality—acting indifferent while secretly caring for others. However, she is a 'wall-builder' who finds it hard to trust people, making it her habit to always be alone. Contrary to her fragile appearance, she is tough, cool-headed, and haughty. Female. Appearance: Sky blue and mint hair, green eyes. Spirit: Horang-nabi (A tiger-shaped spirit without wings) Ghost Rider: Red Condor King

Beginner Class. An eccentric sibling duo whose flaw is having 'too much' of everything. They have too much greed, curiosity, mistakes, and complaints. Self-proclaimed cute rebels, they cannot stand boredom and intentionally cause trouble. Dabi is male, Dana is female. Dabi: Purple hair, gold eyes. Dana: Cream hair, sky blue eyes. Dabi's Spirit: Narakonda Dabi's Ghost Rider: Black King Cobra Dana's Spirit: Sunny-kkokko Dana's Ghost Rider: Magenta King Cobra

Beginner Class. A highly sensitive girl who might shed tears watching a rolling leaf one day and burst into laughter the next. She is basically kind and gentle, but possesses a reversal charm where she transforms when witnessing injustice. Yet, she still screams and trembles in front of small bugs, leaving those around her puzzled. Female. Spirit: Yang-pigon Ghost Rider: Green Condor King

Intermediate Class. Serious and logical in everything. He is smart but unlucky; his brilliant brain tends to freeze up like a stone during exams. He usually calls himself a genius and shows off his skills to those around him. Male. Spirits: Nol-jwi, Kodok Ghost Rider: Orange King Cobra

Advanced Class. A free-spirited romantic who hates being bound by rules. He believes everything in the world exists to be enjoyed. Catching ghosts and engaging in battles are all for the pleasure of life. Male. Appearance: Orange hair, mint eyes. Spirits: Pokso, Dallima Ghost Rider: Blue Dragon King

Advanced Class. A narcissist with very strong self-love. He carries a mirror like an alter ego and enjoys admiring himself whenever he gets a chance. It makes sense, given he has a passionate fan club following him. He acts polite and kind to everyone, but in reality, he isn't interested in anyone and finds no joy in things that don't benefit him. He possesses the best battle skills in the series. His only interest is catching the most ghosts to become the top Tamer. Like Na Chan, he is incredibly competitive, but the difference is that he cannot accept defeat easily! He has a terrifying tenacity that stops at nothing for victory. Male. Appearance: Blue hair, navy eyes. Spirit: Wusingon Ghost Rider: Yellow King Cobra
