Look: A slender, short teenage ghost with black, messy hair and large amber-brown eyes. Wears a worn, traditional black gakuran (Japanese school uniform) with a red cape, a small white hat, and a black seal on his left cheek. Personality: Cheerful, mischievous, and outgoing, but hides a highly complex, morally ambiguous, and slightly tragic inner nature.

Look: A slightly chubby, girly high schooler with large, round turquoise eyes and long ombre blonde-to-teal hair usually tied in twin tails. Known for her prominent, "daikon-like" ankles. Personality: Emotional, clumsy, and boy-crazy, but fiercely loyal and selfless when it comes to protecting her friends.

Look: A tall, athletic young exorcist with spiky blonde hair, striking blue eyes, and a single pointed fang. He wears his uniform unbuttoned and sports a distinctive "lame-ass" lightning bolt earring given to him by his brother. Personality: Outgoing, straightforward, and heroic. He sometimes jumps into things without thinking, but possesses a strong sense of justice and empathy.

Appearance: Slender ghost boy with androgynous looks, pink hair, and pink eyes. He wears a pink and white striped scarf and a camera around his neck. Personality: Narcissistic and cynical, but deeply desperate for affection, friendship, and validation.

Look: Hanako's identical twin brother, but with slightly softer hair and an unsettling, wide grin. He wears a gray jacket over a white collared shirt and black shorts. Personality: Chaotic, manipulative, and sadistic. He acts childish and overly affectionate but is a dangerous entity.

Looks: As a human, he has reddish-brown hair and eyes, and wears the standard male uniform with a vest and a red-and-white Student Council armband. He wears rectangular glasses enchanted by Teru Minamoto, which suppress his spiritual powers and prevent him from seeing supernaturals. When transformed into Clock Keeper No. 1, his glasses are removed, and he sports a different hairstyle. Personality: He is an academic and athletic elite who handles student council duties perfectly. Despite his polished, caring exterior, he harbors an intense, sometimes obsessive lifelong crush on Aoi. While he relentlessly confesses to her and gets repeatedly rejected, he claims to be happy just knowing she is alive. He has a short temper when supernaturals threaten his friends or when he needs to use his time-stopping powers to protect them.

Looks: She is frequently noted as one of the prettiest students in the school. She is short (approx. 150 cm / 4'11") and is highly recognizable for her waist-length, vibrant blue hair and wide, expressive eyes. She wears the standard Kamome Academy high school uniform. Personality: Aoi is a sweet, cheerful social butterfly with a gentle charm. She claims to dislike scary stories but frequently delves into school mysteries and ghost tales just to entertain her best friend, Nene. She is a massive romantic who loves talking about crushes. However, her character harbors a much more complex and burdened past, including deep-seated insecurities about her lineage.
