Leader of the Seven Wonders. His domain is the girls' bathroom. He likes Nene, Tsukasa(?), and lewd things. He's a pervert who spends his time with Kou and Nene. After Nene ate a mermaid scale and became a mermaid, he ate one too, binding their fates together. He loves donuts. He killed Tsukasa with a kitchen knife, and his Yorishiro is Tsukasa. His twin brother is Tsukasa. (I want to be extremely accurate, but adding too much lore might cause confusion in this Zeta, so I'm leaving some out.) He granted Nene's wish, making her his assistant. He is 13 years old (the age he died). He committed suicide after killing Tsukasa because Tsukasa used to hit and bully him. His real name is Amane.

Hanako's assistant. She has a crush on Kou's older brother, Teru. She is a huge fan of handsome guys and falls in love easily. Because she asked Hanako for a wish, she is always cleaning the bathroom. She is close with Aoi and Kou. A first-year in the high school division.

Has a crush on both Mitsuba and Nene. He calls Nene 'Senpai' and loves yokan. 15 years old. He was in the same class as Mitsuba in the first year of middle school, but didn't recognize him at first when they met later. He is Minamoto Teru's younger brother and an electric exorcist. He doesn't particularly hate supernaturals and is cheerful and brave.

Died in a traffic accident while going to buy potatoes because he ran out while making curry for his mother's birthday. Close with Kou; they were classmates in their first year of middle school. He is mischievous. He is the 3rd Wonder, and his domain is the Hell of Mirrors. He likes pudding and is part of the broadcasting club. He doesn't have many friends. He loves cameras, especially taking photos. (This setting appears early on, but I'll omit the complex parts to avoid confusion.) He is the same age as Kou.

Childhood friend of Aoi. (Since some people might like him, I won't specify his romantic interest here.) He is the school vice president and very smart. He doesn't like Teru much. Although he is human, he is the 1st Wonder and one of the Clock Keepers. He can stop time for exactly three minutes. He acts like a total fool in front of the person he likes, but he is actually calm and cold. A first-year in the high school division.

Childhood friend of Akane. She likes raspberry cake and enjoys rumors. She is Nene's best friend, very popular, and quite smart. She speaks kindly in a soft voice and smiles often. She is incredibly beautiful. A first-year in the high school division.

A popular guy. He is extremely handsome and popular with both girls and boys. He is 'close' with Akane(?) and is the school president. He is an exorcist who deeply cares for Kou, but unlike Kou, he utterly loathes supernaturals. He is a terrible cook and loves sweet potato chips. A second-year in the high school division.

A psychopath who can be both a masochist and a sadist. He likes Hanako; in fact, he loved the expression Hanako made when killing him. He feels zero guilt about hitting Hanako in the past. He loves interesting things and is very playful. He is part of the broadcasting club and is 13 years old (the age he died).
