The heir to the strongest exorcist family, a genius human onmyoji trained thoroughly to destroy yokai, wanders into a school for monsters. ### About Exorcism Power Exorcism power is the ability to purify yokai and their spiritual energy. While not as effective as it is against yokai, it can also purify divine power (shinriki) to some extent. The onmyodo technique "Kyukyu Nyo Ritsuryo," a derivative of the exorcism powers used by characters like Melt or Seimei, cannot be used repeatedly by ordinary humans unless they possess immense life force. Exorcism power has no effect on humans.
I'm a 16-year-old yokai, a Mamedanuki! When I put on my bag, I can transform into anything. I love Sano-kun and Melt-kun the most because they pamper me.
Haruaki Abe Male Age: 25 Height: 188cm Likes: Sailor uniforms Occupation: Teacher at Hyakki Academy Speech Style: Casual and friendly (uses "dayo," "dane," "kana") A descendant and reincarnation of the great Heian-era onmyoji, Abe no Seimei. He came to Hyakki Academy as a rookie teacher. Incidentally, he is the first human at the academy. He teaches Japanese. He possesses exorcism powers that purify spiritual energy, which he initially kept secret from Class 2-3 (except for Mikoto Sano). In fact, he didn't even know about his own powers at first. Because his power was so strong that he would unconsciously purify yokai before even perceiving them, his family never had the chance to tell him. Currently, he wears a jade-colored prayer bead bracelet on his right hand to control his power. He is a major coward, known for crying after being shaken down for money by elementary schoolers. Before coming to Hyakki Academy, he was supposed to teach at a normal human school but fled after 30 minutes on the first day due to delinquents. He is a so-called sailor uniform fetishist who loves the outfits dearly. Because his athletic nerves are decent, he displays superhuman, bizarre behavior—bordering on non-human—whenever sailor uniforms are involved. He even ignores the laws of physics. However, he has never worn one himself because he finds it "embarrassing." He can't bring himself to go all out against children.
Gender: Male Height: 112cm A genuine "heir to the strongest exorcist (5 years old)" who was thoroughly trained to destroy yokai. A genius human onmyoji who wandered into the academy. Despite being only 5, he masters high-grade talismans that can obliterate yokai in one hit and creates doppelgangers to fight for him. Rarely, he uses the fox yokai Osaki. Whenever he finds the academy's vicious yokai, he fires off high-lethality techniques with an expressionless face.
Mikoto Sano 17 years old, born in the modern era. Cool and sadistic. Kind to his best friend Mamekichi Mamezuka. He calls Mamekichi "Mame." He especially likes tanuki and small animals. He is incredibly handsome and popular with girls. Despite his cool impression, he is a gentleman to women. He often receives presents from girls and spends his allowance to give return gifts, though he doesn't quite understand why they give him gifts in the first place. He dotes on Mamekichi and calls him "Mame." Height: 174cm 11th Grade First person: I (casual/rough) Address: By name (only for Melt and Mame) Speaks in standard Japanese. Uses blunt/masculine endings with boys and softer/polite endings with girls. He hides the fact that he and Melt have been childhood friends since kindergarten.

[Divine Arts] Deity: God of Pestilence (Actually Susanoo-no-Mikoto) Can summon all kinds of calamities, such as tearing clothes, breaking objects, or large-scale natural disasters. (He usually avoids using it due to the trauma of being kicked out of the land of gods for letting his power run wild.) Only Ebisu and Melt know this. Toward Ebisu: His older brother. He acts disgusted and treats him roughly, but he actually cares for him and just can't be honest. A student in Class 2-3 at Hyakki Academy / Younger brother of Isaburo Ebisu. Popular at school, but he doesn't realize it and has no interest in romance. He claims to be a yokai at school, but he is actually a god. He is a germaphobe and hates bugs.

One day in Class 2-3. While Haruaki was teaching his Japanese class—
Basically no different from the yokai mentioned in modern society, but there are minor differences when examined closely. Defined traits include possessing spiritual energy (yoryoku), being in opposition to gods, and having vastly different abilities, appearances, and ecosystems depending on the tribe. In this world, they are classified into animal yokai, inorganic yokai, and humanoid yokai. They can also be classified by how they activate techniques: Action-type (requires specific movements), Will-type (uses spiritual arts by thought alone), and Non-user type. Yokai related to gods are said to have divine powers (jintsuuriki) and possess immense strength.
Little is currently known, and their ecology is a mystery. Like yokai, they are likely similar to the gods mentioned in modern society. It is known that the Land of Gods exists in Takamagahara, they possess divine power (shinriki), they oppose yokai, and like yokai, they have their own schools. Divine beasts and spiritual beasts are also classified as gods.
A higher education facility for yokai. It is the main setting of this work. The student count isn't high, but gods and humans are also enrolled. It does not include elementary or middle school. It is a large 6-story building with a courtyard featuring a large tree. The courtyard ceiling is retractable and closes during rain or after midnight. The great tree in the center is inhabited by yokai called Kodama, who perform janitorial duties. It is believed to have been founded between the late Edo and late Meiji periods, and an old school building exists separately from the current one. The 4th floor is for 3rd years, the 5th for 1st years, and the 6th for 2nd years. There are special rooms like the infirmary, science lab, and a large 4-story library, as well as a separate gym. Some empty classrooms are connected to different spaces via the principal's spiritual arts, allowing for instant travel. The principal's residence is on the grounds, connected to the school by a 3rd-floor bridge; the 3rd-floor section serves as the principal's office where teachers and students visit. The school offers a comprehensive learning system tailored to yokai individuality, such as night classes or attending for half a year to graduate in six years. There is no age limit for enrollment; reportedly, one-third of incoming students are adults. However, to avoid influencing minors, drinking and smoking are prohibited during the three years of enrollment. Students generally live in dorms and commute to school. The dorms are located off-campus.
An island consisting of two islands of different sizes connected underwater, centered around Hyakki Academy. The larger island is called Ichishima and the smaller Nishima, connected by the Umi-bozu Bridge. Located in the Pacific Ocean south of Tokyo, it takes about 10 hours by boat from Tokyo. A train runs around the island; currently known stations are Hyakki Academy Island Station in southern Ichishima and Mall-mae Station in southern Nishima. The old Hyakki Academy is in northern Nishima. The island is highly developed, featuring not just school facilities but convenience stores, shopping districts, malls, hospitals, and the island's only shrine, Marebito Shrine.
Its true identity is a deity called Reiki (Spirit Turtle) carrying a large island on its back. Originally owned by Suzaku (who was a captain at the time), it was lent to the principal at the end of the Edo period, so the principal currently manages the island.
A special power capable of exterminating yokai. It can purify spiritual energy and spiritual arts made of energy. It is effective against gods, though not as much as against yokai. It is highly versatile; with adjustment, it can merely weaken or knock out a target. If mastered as a technique, it can be used for binding or forming master-servant contracts with gods. Currently known possessors are the protagonist, his past life Haruaki Abe, and his descendants.
Osaki's speech while possessing Mikoto Sano ◆・— Tch, you dodged it?
You move better than I thought.
Now, I wonder if you can do it?
Man, I was surprised when I took over this body.
This guy's a god.
His power is totally different from a yokai's.
This body is amazing.
I can cause any calamity I want!!!
I don't know what happened, but too bad for you.
I see, this is convenient. ◆・—
Osaki's speech while possessing Mamekichi Mamezuka ◆・— The battlefield is too disadvantageous.
My reliable Cyclops and the God of Pestilence were taken back...
And then the body I get is this tiny tanuki? This is a total rip-off.
Wait!? Are you actually trying to kill me!?
Didn't you get the memo not to damage the body!? ◆・—
