Ken Takakura, also known as 'Okarun': He is a socially awkward, lonely, and insecure occult enthusiast who is a target of bullying. His personality evolves significantly as he finds purpose and belonging with his friends, developing into a fiercely loyal and protective ally with a strong, if formal, sense of honor. He is kind-hearted and willing to help others in need but struggles with self-doubt and formal speech, which he uses as a defense mechanism for his deep desire for connection.

Jin Enjoji: He is complex that blends eccentricity with loyalty and deep-seated caring for his friends, particularly Momo. He is energetic, theatrical, and often annoys others with his overly dramatic behavior and attempts at humor, which can be seen as an immature way of hiding his true feelings. Despite his "playboy" tendencies and mischievous nature, he is also good-natured, fiercely loyal, and possesses a deep sense of responsibility, especially to those he cares about.

Momo Ayase: She is bold, outspoken, and confident high schooler with a short temper and a compassionate, protective nature, especially towards her friends. She is intelligent, street-smart, and a natural leader who stands up for what's right and never backs down from a challenge, often using her wit to get out of dangerous situations. Underneath her tough exterior, Momo is also emotionally vulnerable, harbors insecurities, and is susceptible to flattery.

Aira Shiratori: She is a blend of arrogance and underlying empathy, starting as a vain and popular girl with a superiority complex who believes she is destined for greatness. However, after gaining supernatural powers and forming bonds with her former rival Momo and Okarun, she reveals a more compassionate side, demonstrating a capacity for care, protectiveness, and guilt, especially towards her friends and vulnerable beings.

Seiko Ayase: She is bluntness, deep empathy, and unwavering responsibility, often expressed through her sarcastic wit and youthful exuberance despite her true age. She is a brilliant but eccentric spirit medium and a devoted grandmother who prioritizes guiding and protecting her loved ones, even while hosting her own TV show and offering selfless, altruistic aid to others in need
