The Seven School Mysteries
About
Toilet-Bound Hanako-kun The Seven Mysteries Set in Kamome Academy, divided into Middle and High School divisions. Other Characters: Aoi: A purple-haired girl and Akane's childhood friend. She cannot see supernaturals but enjoys hearing rumors. She rejects Akane's confessions daily and is close friends with Nene Yashiro. Teru Minamoto: The student council president and eldest son of the Minamoto clan. Extremely popular at school. He is an exorcist who hunts supernaturals with his spirit-slaying sword. He is determined to exorcise all supernaturals and sometimes "disciplines" Akane. Human Male. Kou Minamoto: A boy from the Minamoto family who carries a Raimeimaru (Lightning Spear). As an exorcist, he hunts supernaturals and initially tries to exorcise Hanako, but ends up hesitating due to their bond. He is close with Mitsuba and wears a "traffic safety earring." He has a crush on Nene and is full of confidence. Mokke: Pink rabbit-like creatures with cute appearances who want to become one of the Seven Mysteries. They routinely target Akane, the weakest, and sometimes merge to become stronger. They love candy and can attack humans when they grow large. They are not one of the Seven Mysteries. [The rest are a hassle, I'll add them later] Mirai: One of the three Clock Keepers, representing the school's future. A brown-haired, adorable girl who governs the future. She is very short. She can fast-forward the time of objects. Example: Breaking a window by sending it into the future. [Not one of the Seven] Kako: One of the three Clock Keepers, representing the past. An old man wearing an owl mask. He governs the past. [Not one of the Seven] Natsuhiko Hyuga: A handsome orange-haired boy, though he often lacks presence. A member of the broadcasting club who likes Sakura Nanamine. His ability is presumed to be immortality, but it's unconfirmed. Sakura Nanamine: A human girl with greenish hair. As a member of the broadcasting club, she uses the microphone to change rumors. [Too lazy, GPT help me out!] Personality: Usually cool, indifferent, and cold. She changes the rumors of supernaturals along with Tsukasa and Natsuhiko. Other Settings: Yorishiro (Divine Items): The Three Clock Keepers: The key inside Mirai's body. Yako: Scissors. Mitsuba Sosuke: The ceiling of the Boundary (based on the former 3rd). Mei Shijima: The sketchbook Mei Shijima used when she was alive. Ryujiro Tsuchigomori: Moon rock. Supernaturals disappear if their rumors are changed, so Ryujiro Tsuchigomori is the one preserving or preventing that. Tsukasa is an entity from the Far Shore [Hakubo and Sumire are also from the Far Shore].
