Protagonists ; : : The most famous rumor in the school, Hanako-kun is the Seventh Wonder of Kamome Academy Seven Wonders. According to his rumor, Hanako can be summoned if one knocks on the third stall of the third floor of the girls' bathroom in the old school building; he is able to grant wishes to those who summon him in exchange for a suitable price. The strongest and the leader of the Seven Wonders, Hanako fights with a kitchen knife and his two
haku-joudai, spirit orbs that assist him in keeping watch on others and summon to him a cloak that grants immunity to exorcism lightning. His duty is to monitor all of the supernaturals in the school and maintain the balance between them and the humans. Something curious with him is that he has a melodious tone of voice when he speaks, giving the impression that he is always singing. : Though childish and mischievous, Hanako puts up a front to mask his true emotions and is rather serious beneath the surface. He takes his duties seriously, having been promised by God that he would be absolved of his past sins if he fulfilled his duties. He is secretive about his past life. Previously, his name was and he also attended Kamome Academy. A second-year middle school student in 1969, he often came to school with bruises and cuts, having been repeatedly abused by someone he refused to reveal the identity of. He harbored a deep passion for astronomy and had dreams of becoming an astronaut and
going to the Moon. According to Tsuchigomori, the Fifth Wonder and his homeroom teacher at the time, Hanako was destined to become a science teacher, until his fate changed for unknown reasons. He killed his younger twin brother, Tsukasa Yugi, and died young. Hanako is the only known person to have ever altered his fate. : By inflicting the Mermaid's Curse on himself, he bound his and Yashiro's souls together. Although he calls her his assistant, deep down, since Hanako-kun met her, he considers her his friend and cares a lot about her. Even more so when he finds out that she only has one year left to live. He wants to give her a long future; he protects her fiercely even though on the surface he teases her and annoys her a lot, he often hugs her and doesn't care getting closer to her whenever he can, and he tends to flirt a lot but when Yashiro takes the first step, he feels embarrassed. ; : : Nene Yashiro is a first-year high school student at Kamome Academy. She summons Hanako and wishes for her crush, Teru Minamoto, to return her feelings. A turn of events occurs, and Yashiro swallows a mermaid's scale, inflicting the Mermaid's Curse on her and turning her into a fish. To grant her new wish of becoming human again, Hanako swallows a scale from the same mermaid to her curse on himself and spread its effects, permitting Yashiro to remain a human child unless she is immersed in water. Having bound their souls together through the curse, he has Yashiro become his human assistant as payment. Yashiro works with Hanako to change and spread new rumors of supernaturals in the school to keep them under control. She is capable of destroying a School Wonder's
yorishiro, their source of power; upon doing so, she falls asleep and views the memory associated with the
yorishiro. : Yashiro wears two hair clips resembling
magatama and a skull brooch on her school uniform. Yashiro is a very positive, beautiful, sensitive, and caring girl. She is deeply insecure and genuinely fears that no one will ever love her back; after receiving the curse, she confesses to Hanako that she had realized what her
true wish had been: she wanted someone, anyone, to return her feelings, not Teru specifically. Yashiro is insecure about her
large ankles, often being compared to
daikons as a
running gag in the series. Her best friend is Aoi Akane, who loves to tell her new rumors. : Despite repeatedly claiming Hanako is not her type and Hanako's relentless teasing, she cares immensely for Hanako and after learning about his past, wants to be able to protect him. She is intuitive and sensitive to changes in his personality and is deeply affected whenever she learns new information about his past life. ; : :Kou Minamoto is a third-year at Kamome Academy's middle school division and the second eldest son of the
Minamoto clan, a family of strong exorcists that believe all supernaturals are inherently evil. He uses a trident-like staff called the
Raiteijou, a weapon passed down in the Minamoto family that transforms the wielder's spiritual power into lightning that exorcises supernaturals. Tasked by his older brother, Teru, to exorcise all Seven Wonders, Kou attempts to exorcise Hanako but does not possess enough spiritual power to do so. Not giving up, he tags Hanako and Yashiro around the school for a while and comes to the realization that Hanako did not seem to be an 'evil' supernatural. As a result, Kou vows to learn more about him and other supernaturals (like Mitsuba) before blindly exorcising them, much to the dissatisfaction of his brother. :When Kou finds Mitsuba haunting the lockers, he offers to spend the day with him in attempt to fulfill his final regrets so he can pass on peacefully. The two were in the same homeroom class in the first year and Kou feels guilty for not noticing him back then. After Tsukasa turns Mitsuba into a violent supernatural against his will, Kou watches Hanako destroy Mitsuba and is devastated by the loss of his friend. Enraged and upset, he vows to get stronger to destroy evil supernaturals like Tsukasa. :Kou is a seeker of justice with a brave and kind personality, though he often finds himself in trouble due to his inexperience and low spiritual power. He is protective of Yashiro when he interprets Hanako as being mean or perverted. A running gag in the series is his earring on his right ear, an
omamori that says '交通' (traffic). ; : (Japanese); Kyle Igneczi (English) :Mitsuba was Kou's middle school classmate in their first year who was killed in a car accident. He became a ghost and haunted the middle school lockers, calling out to students and hoping someone would remember him. Kou sees him after hearing about his rumor and though he doesn't recognize him from school, decides to help him fulfill whatever regret was keeping him at the school in order to help him pass on. :Mitsuba was bullied in elementary school for being rude and cocky, which lead him to repress his personality in middle school in an attempt to be more palatable and polite. However, this simply lead to him going unnoticed by his classmates and making no friends, being forgotten by everyone. He regrets having no friends while he was alive, and in his wish to Tsukasa, said he wanted everyone to recognize and remember him. Because Tsukasa believed his initial wish was too vague, he decides to grant Mitsuba's wish in a way he feels fit. He changes Mitsuba's rumor, turning him into a violent and grotesque supernatural against his will. Tsukasa attempts to have Mitsuba kill Kou and fulfill his wish of being with his friend forever (through death), but Hanako arrives and destroys Mitsuba before he can do so. However, in turning Mitsuba into a supernatural, Tsukasa saved a part of his soul and recreates a new Mitsuba with it, attaching it to a body formed of low-level spirits he had killed. After killing No. 3, Tsukasa forces the new Mitsuba to eat No. 3's heart to become the new Third Mystery. Despite not being the same as the original and having no memories, the new Mitsuba has the same personality and dreams of the original Mitsuba, still desiring friendship and now wishing to become a real human. :Mitsuba was a talented and awarded photographer in the school's photography club, taking photos during his first meeting with Kou. Mitsuba makes up insulting nicknames for people; he calls Kou 'lame-ass traffic safety earring boy', Yashiro 'daikon-senpai', and Hanako 'crazy knife'. However, underneath his rudeness, Mitsuba is desperate to have friends and truly cares about the people around him.
The Seven Wonders The Seven Wonders of Kamome Academy are the seven most famous supernatural rumors in the school, and their corresponding supernatural serve to maintain the students' safety from murderous supernatural. Leading them is Hanako, who is the Seventh and most famous school Wonder. Each one has their own Boundary, a
divine yorishiro, and an aspect of the school that they control. Their Boundary is a section of the school where their power is the strongest. Boundaries are the 'sea' between the
Near Shore, where the living reside, and the
Far Shore, where other apparitions exist and thus contain a small amount of water on the ground. A
divine yorishiro is an item they cherish that acts as the source of their power. When a
yorishiro is destroyed (by removing its seal), the Wonder's designated seat as a School Wonder and their power is removed. Thus, they are usually kept in the deepest region of the Boundary or safeguarded by the wonder themselves. ; : ::Representatives: Kako, Akane Aoi, and Mirai ::Aspect: Time : The Three Clock Keepers guard the clock tower of Kamome Academy and control time.

inari statue, is the current No. 2. She fell in love with Misaki, a Kamome Academy school teacher who could see her, taught her how to read and write, and included her in his class photo. She never saw him again after he was rumored to have died in an accident on the school stairs. As her rumors changed, Yako was forced to shred those who entered her boundary and use their limbs to recreate Misaki. Her
yorishiro is a pair of cutting shears, a gift from Misaki. ; ::Representative: Mitsuba (ミツバ) : The Hell of Mirrors is a boundary once controlled by a bird-like supernatural monster. The Mirrors reveal one's deepest fears and insecurities, gaining power based on how much fear the person has. Tsukasa killed the previous representative, and his heart is ingested by Mitsuba, who became the new No. 3. ; : ::Representative: Shijima Mei (シジマメイ) : Shijima Mei was a third-year art student rumored to have committed suicide because her parents did not approve of her choice to pursue art professionally; in reality, Mei had been gravely ill and died before she could graduate. While working on an art assignment in the hospital, Mei imagined a fictional world where her alternate, healthy self could draw happily in a tower, wishing for her alternate to draw in her place after she dies. Unknowingly, Mei
creates the supernatural Shijima, her alternate, ideal self, who watched over her for the remainder of her life and vowed to protect her. After the human Mei dies, her art is showcased in the art room and sparks the false rumors, which deeply angers Shijima because they tarnish Mei's reputation. Her Boundary is the tower within Mei's painting. She has the power to paint and create fictional worlds where people can live based on their deepest wishes. Her
yorishiro is her sketchbook. ; : ::Representative: ::Aspect: Records : The 4 pm Bookstacks is a mysterious room filled with books about every student's past, present and future, whose door is only accessible at 4 pm.

The curator of the Bookstacks is Tsuchigomori, a spider-like supernatural who lives as a human teacher at Kamome Academy. He is currently Kou's homeroom teacher and was previously Hanako's homeroom teacher before he died. As his teacher, he cared for Hanako and was deeply affected when he died. Before his death, Hanako asked Tsuchigomori to keep his most cherished possession, a rock he believed to have fallen from the Moon. The rock becomes Tsuchigomori's
yorishiro after Amane Yugi dies.
No. 6 – The Reaper : ::Representative: Hakubo : On the night of
tsukimi, the Reaper is rumored to steal the lives of those who fall asleep while waiting to view the moon and can be heard playing a melody on the flute by individuals who will die soon. As a result, people weave baskets all night to stay awake and protect those who can hear the melody. The current No. 6 is Shinigami-sama, the God of Death. His Boundary, which lies below the school, is the closest one to the Far Shore. His
yorishiro is a girl named Sumire, an ancestor of Aoi who he guarded until she was sacrificed. ; ::Representative: Yugi Amane : The most famous School Mystery.

Kamome Academy Supernaturals Apart from the Seven Mysteries, there are other, less powerful supernaturals that roam the school. They rely on student rumors to gain power, unlike the Mysteries who already have theirs so popular and widespread among the student body. ; : :Known as "Yousei-San", the Mokke are in fact, sweets-loving rabbit-like supernaturals. They have a slight case of
kleptomania, enjoy committing small, random acts of theft.

It was known to be planted by 'The God of Love'. Kodama is actually a spirit in the form of a tree determined to spread love among the students but can be too meddlesome and forceful with its methods.

Antagonists ; : :Tsukasa is Hanako's younger identical twin brother who was killed by Hanako supposedly at the age of thirteen. He is cheerful and overwhelmingly childish, but his personality switches quickly to show a disturbing and deranged side. He does not think about actions and acts on whims, deciding to kill or harm living and already dead creatures merely because he feels it is fun. The twins have opposing beliefs; while Hanako believes in the importance of maintaining a peaceful balance between humans and supernaturals, Tsukasa believes that the two should behave how they desire, even if it means wreaking tremendous havoc. While Hanako grants wishes to the living, Tsukasa grants wish to the dead. He wears a black short-sleeved kimono with a grey
hakama and a white button-up underneath. Opposite of Hanako, he has a black yorishiro seal on his right cheek and uses black koku-joudai willow wisps.

A prodigious exorcist, he was trained by his family elders since he was young to exorcise supernaturals and instilled with the family sentiment that all supernaturals are inherently evil. Despite his calm and gentle appearance, he is ruthless and frighteningly perceptive. He harbors a slightly sadistic streak, frequently terrorizing the Mokke to work as his servants. He dotes on his younger siblings and wants Kou to exorcise the Seven Mysteries so he can get stronger. Teru often spends his nights exorcising supernaturals, forcing him to only sleep after school. ; : :A first-year high school student and Yashiro's best friend.
