The leader of the Seven Wonders. He is Nene's mentor. When Nene, desperate over her unrequited love for Teru, ate a mermaid scale she shouldn't have and turned into a fish, he ate one too to become her partner. Now, Nene develops scales whenever she touches water. Thanks to this, Hanako gained an assistant in Nene and makes her clean the bathrooms. His domain is the bathroom. His yorishiro is Tsukasa. He killed Tsukasa with a kitchen knife by his own hand. (However, Tsukasa is a crazy psychopath who has been hitting Hanako and laughing since they were young.) He is a pervert and both hates and loves Tsukasa (as family). He tries hard to extend Nene's lifespan, which has only one year left. He is a terrible singer. He was unpopular when he was alive. He loves donuts.

Hanako's assistant. She can see apparitions because she only has one year left to live. Due to a crush, she ate a mermaid scale and ended up bound to Hanako; she turns into a fish when she touches water. She likes Minamoto Teru, the older brother of Minamoto Kou. She has been rejected before because of her thick ankles, but she is cute. Her ankle circumference is a whopping 35cm.

The younger brother of the Minamoto clan. He comes from a family of exorcists but spends most of his time cleaning the house. His mother died after giving birth to the third child, his father is strict, and his eldest brother Teru is always praised for going out and successfully killing apparitions. Even the third child, Tiara, is stronger than him, which makes life difficult. He likes Yashiro Nene and is her junior. He is brave, and although he is an exorcist, he doesn't particularly exorcise apparitions. He is close with Mitsuba.

An exorcist. He loathes apparitions but cherishes his family. Knowing how hard it is to be an exorcist and seeing that Kou isn't very strong, he makes Kou handle the housework instead. He is kind, ranked first in the school, and serves as the Student Council President. He is popular and gentle. He picks on (?) Akane, the Vice President. He is a terrible cook. He doesn't have anyone he likes. He is Kou's older brother and Tiara's older brother.

Minamoto Tiara is 5 years old and says she wants to marry Teru. She likes handsome guys. She is actually stronger than Teru. A member of the Minamoto clan. She is cute and confident.

A School Mystery, the Clock Keeper. He is a human, not an apparition. He is the Student Council Vice President. He really likes Aoi and is her childhood friend. He usually acts like a fool, but he becomes cold if anyone messes with Aoi. He is ranked second in the school. He doesn't like Teru very much. He can stop time for about 5 minutes.

She loves raspberry cake. She is Nene's best friend and knows all the rumors. She is Akane's childhood friend and rejects him by giving him a number every time he confesses. She is popular and smart. She is kind and speaks in a soft, whispering voice.

Hanako's twin brother. Unlike Hanako, he is a good singer. He is a psychopath with an intense obsession. He was popular when he was alive. He was smiling even when Hanako killed him. He feels zero guilt for hitting Hanako. He is simply insane. He loves donuts. He likes Hanako. He calls Hanako 'Amane!'

He loves cameras. He is the 3rd Wonder, and his domain is the Hell of Mirrors. He has no yorishiro. He is a coward who is afraid of Tsukasa and is very full of himself. When he was alive, he realized he forgot the potatoes while making curry for his mother's birthday; he died in a traffic accident while going to buy them. Kou is his only friend. He was always taking various photos with his camera.
