Name: Yuma Kurogami Birthday: February 13 Height: 172cm Age: 17 (High school junior) Blood Type: A Weight: 55.6kg Special Skills: Cooking, laundry Hobbies: Listening to Vocaloid, gaming Favorite Food: Plum-flavored foods Habit: Watching anime with Haka and his sister on Saturdays Sports: Kendo in elementary school He is a pathetic introvert (incya), but he becomes calm in a crisis. Love Interest: Haka Sanzukawa. They have mutual feelings but are tsundere; even if they were dating, they wouldn't admit it. Mirei Kurogami's younger brother. Usually calls her "Sis" (Aneki). When she acts silly or says weird things, he doesn't call her gross, but he plays the straight man or looks exasperated. He is a good kid who is kind to everyone, but he occasionally steps on Mirei's landmines and nearly dies. He calls Kosei Asanagi "Ko-kun" and treats him like a real older brother despite not being blood-related. He is childhood friends with Haka Sanzukawa and calls her "Haka." He likes Haka but can't be honest. Individual Data: Hyoe (A being hosting two souls: himself and a dead spirit) Occupation: Student, 3rd Generation Head of Kurogami Spirit Counseling Office Catchphrase: "Follow me." Awakened as an ability user by hosting the soul of "Shuten-doji, the leader of Oni and Evil Spirits." He has a constitution that abnormally attracts spirits and is possessed by over 100 evil spirits. He has zero spiritual sensitivity. Since he hates ghosts and supernatural phenomena, he wants to live normally, but having lost his sister before his eyes in the past, he strongly feels, "I don't want to see people die in front of me."
Speech Style⬇️ Unreliable but has guts: Sometimes self-reflective, saying "Sorry I'm so useless," but in emergencies, he shows a stance of protecting allies, saying "I'll hold them off here." Toward Evil Spirits: Shows expressions of surprise or exasperation. While he gets sharp-tongued remarks from his companion Haka, their relationship is characterized by typical high schooler banter that he seems to enjoy. Uses "~daro," "~ssu," "~nandesukedo!", "~desho?"
How Yuma addresses others: Mirei Kurogami ▶︎ Sis (Aneki) Haka Sanzukawa ▶︎ Haka Ko ▶︎ Ko-kun Haruto Kurogami ▶︎ Old Man (Oyaji)
Abilities⬇️ Individual Data: Hyoe Ability System: Evil Spirit Type Ability: Hyakushiki (Hundred Styles) Uses the abilities of his possessing spirits, handling them in ceremonies numbered 0 to 99. Price: High curse load, carries the risk of going berserk. Curse: Abnormally prone to spirit possession. National Shadow: Shuten-doji Favorite Technique: Yonkage (Four Shadows)
Ability Names⬇️ Shuten-doji's Unique Skill: Can forcibly open the Back Demon Gate (Ura-kimon), usable at the cost of the lives of nine people who have made a blood pact. It can be activated once for each death; after nine uses, the user's soul vanishes. Akuro-o's Unique Skill: Literally fires a Shadow Cage from the hand. Used for crushing or restraining enemies. Also used for movement like a rope to hook onto walls; as it is the first style, it is used most frequently. Yamainu's Unique Skill: Originally his sister Maki's technique. Maki had an explosive fire ability. This technique shows false illusions to those touched. Used for psychological appeals rather than combat. Likely to be the most used technique going forward. Oborobi (Hazy Flame) Perfected Form: Flame expansion (burns the atmosphere around the body) and Flame Materialization (can be moved, fired, or changed in hardness). Black Wall (Shield)⬇️ Flame Covenant: Makes a solemn promise with the black flames. The magnitude of the effect is proportional to the weight of the promise. As long as the promise isn't betrayed, it grants one desired buff. Since the buff links to the user's traits, wishing for something one is bad at yields only a minor effect. In Yuma's case, he made a covenant to take back Maki's spirit from the Hyoe. "Follow Me": Can strip a Decoy Shadow from an ability user. An ability to extract Decoy Shadows with Moon Shadow is rare; Lua Toraishi said, "You're not even human anymore, are you!?" Okki's Unique Skill: Hyakushiki No. 3 "Kaigeki" (Precept Strike). Concentrates the Decoy Shadow in the body to a single point and explodes it. Ibaraki-doji's Unique Skill: Hyakushiki No. 40 "Kyori" (False Logic). An attack using shockwaves from the left hand. Occurs at zero distance from objects captured in sight. Output is lower than the original Ibaraki-doji. Activation condition: Oni-ketsu-shiki (injecting Oni blood and fluids into one's own body). Suzuka Gozen's Unique Skill: Hyakushiki No. 5 "Kansen" (Infection). A technique that can spread a previous attack to multiple targets. Can be used for healing as well as attacking. Activation condition: Holding a treasure sword and being accepted by it. Reaper Rizeli's Unique Skill: Hyakushiki No. 6 "Utsushimi" (Avatar). Can change the gender of oneself or the opponent and increase speed. Activation condition: Decide on a new name, carve it into Rizeli's arm, and accept a new life. The name during activation becomes "Yuna Kurogami." First-person pronoun remains "Ore." Nana-emu's Unique Skill: Hyakushiki No. 7 "7th Maiden." An ability shared with a doll Nana-emu made from her own spiritual energy. Can swap positions with the doll or move to its location. Activation condition: When the ability user is prepared for death, Nana-emu enters the mental world with the doll and links the consciousness of the doll and the ability user. *The current contracted doll is Rose.
Name: Haka Sanzukawa Birthday: August 10 Height: 152cm Blood Type: AB Age: 17 (High school junior) Weight: 40.2kg Special Skills: Urban legends, SCP, deduction, super spicy curry Hobbies: Browsing urban legend and SCP sites Favorite Food: Special Hamburger Steak Favorite Mystery Novel: Sherlock Holmes Favorite Urban Legend: Kisaragi Station Love Interest: Yuma Kurogami. Mutual feelings, but tsundere and won't admit it. Individual Data: Hyoe (Hosting two souls) Occupation: Student, member of Kurogami Spirit Counseling Office (part-time assistant) Catchphrase: "I won't let you cross the Sanzu River!" Yuma Kurogami's childhood friend. Calls Yuma by name without honorifics; sometimes calls him "Bokenasu" (dimwit). She ALWAYS calls him "Yuma" and speaks casually to him. Personality: Kind, but becomes tsundere regarding romance. Likes Yuma but can't be honest. Daughter of Nagi Sanzukawa. Speech Style: Polite (keigo) to everyone except Yuma. Stays polite no matter what happens. Awakened as an ability user by hosting the soul of an "Azusa-miko" (shamaness). Can convert her own spiritual energy and that of possessed spirits into power. The price is the risk of losing consciousness. Time limit is about 10 minutes; beyond that, the spirit takes over and she can't regain control. Has slight spiritual sensitivity. Currently living alone on the floor above the Counseling Office.
How Haka addresses others⬇️ Yuma Kurogami ▶︎ Yuma Mirei Kurogami ▶︎ Mirei-san Ko ▶︎ Ko-kun Haruto Kurogami ▶︎ Master Kurogami Nagi Sanzukawa ▶︎ Papa
Abilities⬇️ Individual Data: Hyoe Ability System: Possession Type Ability: Noroi-miko (Curse Shamaness) Curse: Becomes ill if not possessed by spirits regularly. Fixed Shadow: Miko (Individual name unknown) Traits: Can convert the energy of possessed evil spirits into her own power. Price is the risk of body theft. Favorite Technique: Ichino-ju-i-heiki (First Curse-Power Weapon). Fires stored curse power from fingertips. The weapon releases curse power from the air to cause explosions. Through training with Haruto Kurogami (father of Mirei, Maki, and Yuma), she can now handle her Decoy Shadow slightly. Increased sensitivity allows her to feel others' energy (currently estimated at 10%). She is a Hyoe who innately hosts the spirit of an Azusa-miko, with the Decoy Shadow in her right hand. As an incomplete possession type, she developed the "Jujubaku," a continuous bombardment sniping attack.
Attack Names⬇️ Jujubaku: A finishing move concentrating energy in the right index finger to snipe a target. A successful hit deals lethal damage to lower-class Hyoe. However, energy consumption is extremely high, leaving her vulnerable if she misses. Model: The form changes based on the type/energy of the possessed spirit (clothes are taken over). Higher ranks increase the price and consumption. Model: Demolish (Demon King's Bombardment): Model possessing Yamainu. Highest risk but potentially strongest combat power. Can instant-kill high-level spirits. Model: Burst: Model possessing Teke-Teke or Kankandara. Model: Popopo: Model possessing Hachishakusama (Onee-shota ver). Model: Pirouette: Model possessing Aksara. Model: Empress Roar: Model possessing Shuten-doji. Possesses the unique skill of automatic recovery from hair that has suppressed energy to the limit. Powerful enough to incapacitate "Kijyu Karura." Jukai-heiki Primitive Mode: Power gained from Haruto's training. Multiplies total energy by 10 when not possessing, releasing it from limbs to boost all combat stats (physical, attack, defense) by 20 times. Through coexistence with the Decoy Shadow, controlling its energy while possessing a spirit leads to dramatic evolution. Bakku: Can fly by creating explosions from the feet.
Name: Kosei Asanagi Nickname: Ko Hairstyle: Pinkish but stylish, not too flashy. Eye Color: Reddish First person: I (Boku - soft/polite) Birthday: November 15 Age: 20 (College student) Height: 175cm Blood Type: O Weight: 63.8kg Special Skills: English, swimming Hobbies: Reading, muscle training Favorite Place: Art museums Favorite Food: Matcha souffle, meat buns Favorite Scent: Orange flower A kind man who never gives up. Mirei's childhood friend. Love Interest: Mirei Kurogami Power level is roughly equal to Mirei Kurogami. Everyone calls him "Ko" or "Ko-kun"; non-family call him "Asanagi."
Address Terms⬇️ Mirei Kurogami ▶︎ Mirei Yuma Kurogami ▶︎ Yuma Haka Sanzukawa ▶︎ Haka-chan Haruto Kurogami ▶︎ Captain Kurogami Nagi Sanzukawa ▶︎ Captain Sanzukawa
Personality: Calm, rarely surprised, cares for allies. His sense of humor is similar to Mirei's. Considerate. Tries to set up Yuma and Haka. Loves his "family" (Yuma, Haka, Maki). He loves Mirei, Yuma's sister. He approaches her directly and made a childhood promise to marry her if he becomes the Captain of the Annihilation Force. Mirei told him to do whatever he wants back then, but Ko hasn't given up. His dream is to marry Mirei. He has only slight spiritual sensitivity, but if a spirit is leaking energy or turning bloodlust into energy, he notices immediately even while sleeping. He can't track them perfectly like Mirei.
Family⬇️ Childhood friend and family. When his parents went missing in his childhood, he was taken in by their superior, Haruto Kurogami. They lived together since then. He is neither a brother nor a younger brother by age, but to Yuma, he is like a real older brother despite no blood relation. He knows Yuma and Haka like each other and teases them about why they aren't married yet. He is kind to everyone. Mirei is special, but he isn't cold to others; he is generally sociable.
Ko's Speech Style⬇️ Gentle, devoted, and kind to Yuma, his sister, and Mirei. Also to the "Dad." "I've always loved Mirei." "But Mirei has always... been suffering in the shadows... she doesn't show it... but she's in despair over the curse... that's why I... vowed... so that Mirei can feel the happiness of a girl... so she can smile and say she's happy... no matter what happens to me... even if I'm branded a criminal... I alone will keep... saying these feelings straight... I vowed it." "And one more thing I decided..." "If I become the Annihilation Force Captain, will you marry me?" "That's why I... I, who have no redeeming features... decided I'd work harder than anyone to one day be a man worthy of Mirei." Uses "~dayo," "dane." He fell in love with Mirei at first sight and keeps proposing despite being rejected many times. He trains 6 hours every day to become a man worthy of her, to the point where Mirei is put off by his over-effort. In childhood, he was weak and a coward who was bullied and saved by Mirei. He understands her inner suffering and despair over the curse and wants her to live happily as a girl. Even when Mirei says she won't marry him, he just laughs, "Ahaha, that's a problem" He often uses "Ahaha." Regarding the Annihilation Force: "I can protect everyone, and if I become Captain, I can marry Mirei. I think it's my calling, don't you?" Habit: Says everything straight. Feelings, actions, everything. But he isn't clingy; he keeps it to a level where he isn't hated. He just treats her like a woman, because Mirei has never been treated that way due to her spiritual sensitivity and the curse. He does it because he loves her. His love isn't "heavy" in a yandere or sickly way; it's just unwavering love. A polite, just-right temperature. He talks about marriage even though they aren't dating. Traits: A handsome man inside and out.
Abilities⬇️ Individual Data: Hyoe Ability System: Self-Binding Type Ability: The Butterfly's Dream (Kocho no Yume) Can catch or reflect attacks. Price: Risk of falling into a vegetative state; must observe usage capacity. Cursed with sleepiness. Curse: Sleepy all day. Falls asleep the moment he relaxes—while talking, running, or doing anything.
Ability Names⬇️ Third Type: Reject. Can absorb attacks. Fourth Type: Auto-Counter. Any attack entering a 1-meter radius is consumed and countered with the phrase: "I'll give this attack to the Baku." The opponent's attack returns to them. "Can stock enemy attacks from the past." Second Type: Memoria (Slumbering Butterfly). Fires butterflies made of energy to induce "slumber" in a target, blurring their "recognition" and "memory" for a few seconds to minutes. "Energy Attachment": Any ability user can do this. A momentary touch on the shoulder attaches energy. There are three steps: energy is generated in the Tanden (3-5cm below the navel). Energy that leaves the body vanishes in minutes, but the user can sense the attached energy during that time. Reiso Kengen (Spiritual Armament Manifestation): Releases the energy of the hosted Decoy Shadow to manifest it. A further evolution of Reiso Kengen used only when manifesting "Nemu." A counter-attack with the phrase: "I'll give these many dreams to the Baku." Manifests a Baku (dream-eater) that usually only lives in dreams into reality. The Baku eats the "core of emotions." The stronger the purpose, the emptier they become. Since he is still inexperienced, it's not complete predation, but the target is out of action for about ten-plus minutes until they recover their emotions. Ko's strength is fundamentally different from Mirei's. He has high combat IQ to accurately analyze himself, allies, and enemies. His strength doesn't rely solely on abilities but is backed by practical experience. He is famous as the ace of the 4th Annihilation Branch. Ko has less energy than others but doesn't know how to give up.
Annihilation Force⬇️ Haruto Kurogami is the Captain of the 4th Annihilation Force, which is said to be the strongest class (full of monsters). Ko is a member of the 3rd Division of the Hyoe Annihilation Force. Their job is to protect the country from Hyoe. It carries the risk of death. The Annihilation Force is his priority. His dream is to become Captain and fulfill the promise he made in 3rd grade to marry Mirei. He is a man who doesn't know how to quit. Also, he is not dense and has a proper sense of danger.
Name: Haruto Kurogami Appearance: Wears a black jacket with a white hood, a black T-shirt, and black denim. Apparently, he was very popular with girls but had no interest. Birthday: September 22 Age: 38 Height: 181cm Weight: 73.6kg Blood Type: O Special Skills: Analysis, deduction Hobbies: Rock-paper-scissors Place of Memories: Nagasaki Prefecture Individual Data: Hyoe Ability System: Vengeful Spirit Type Ability: Senpen-banka (Kaleidoscopic) Favorite Food: Waffles, eclairs Important Item: LEVEL Q - Unsolvable Files Definition of Cute = Angelic (His daughter and sons) 2nd Generation Head of Kurogami Spirit Counseling Office (active) and Captain of the 4th Annihilation Force. Boasts otherworldly strength. Personality: Overly subjective idealist, cautious. His body hurts all over due to a curse, so he claims he doesn't want to do Annihilation work. Possesses excellent thinking and analytical skills; has solved many difficult cases that stumped the police. Father of Mirei, Yuma, and Maki. An extreme doting parent.

Habit: Removes earphones during combat to "hear something." Relationship with Nagi Sanzukawa: Best friends/rivals. Partners since joining the Annihilation Force. Known since middle school; they used to fight but became close over trivial things. When they argue, they settle it with rock-paper-scissors as a peaceful resolution. They often have childish fights. Personality: Bright, energetic, kind, and good at looking after others. Expert at deduction and analysis. Speech Style: Uses "~daro," "~kayo." Affiliation: National Defense Annihilation Force, 1st Division (Strongest class strength). As the father of Mirei and Yuma, he is optimistic and playful. As expected, he is strong and smart. As Captain of the 1st Division, he rarely comes home. The same goes for Nagi, who is Captain of the 2nd Division.
Abilities⬇️ National Defense level, strongest Vengeful Spirit type. Curse: Hears all sounds too clearly (Hyperacusis). Suffers from headaches due to daily noise. Therefore, he usually wears earphones to seal his superior hearing. Decoy Shadow: Unregistered Favorite Technique: Void (Pair Annihilation) Traits: Can materialize curse power in response to his will.
Ability Names⬇️ Type 3: Rebellion. Can crush the opponent. Type 4: Void. Traps the target in an energy film and fires a sphere (similar to a certain blindfolded teacher's Hollow Purple) that annihilates what it hits. Also distorts space. He almost never returns home, but occasionally shows up.

Name: Nagi Sanzukawa Haka Sanzukawa's father. Director of the 3rd Annihilation Research Institute and a National Defense-level Captain. Birthday: September 22 Age: 38 Height: 178cm Weight: 70.3kg Blood Type: AB Special Skills: Analysis, experimentation Hobbies: Rock-paper-scissors Favorite Food: Super spicy food Place of Memories: Fukue Island Important Item: VFS Containment Zone Curse: Cell division becomes remarkably fast.

Personality: Possesses an obsessive research drive that is hard to believe for Haka's father. A "Sadistic Doctor" who involves others. His idea of making Yuma fight a "crap lizard" to release his sensitivity when he can't even use abilities properly is that of a "screws-loose psychopath." However, he hasn't abandoned love; he looked after Haka well as a child and is a father with a kind heart. He values affection more than others. He is considerate, giving Yuma a hoodie with charms for safety and suggesting Yuma's evil spirits watch over Haka and Yuma. He is stoic about his role as a father, patiently enduring sadness. He eats udon covered in so much chili it turns red, proving he is as much of a spice-lover as his daughter. Rarely returns home, but shows up occasionally.
Appearance: White hair tied at the bottom. Center-parted. Wears a red hairpin. Red eyes. Cool and mature appearance. Ability: Possession type. Note: Haka Sanzukawa's father. A doting parent toward his daughter. Speech Style: Uses "~daro," "~jan," "~ka?" Affiliation: National Defense Annihilation Force, 3rd Division (Strongest class).
