Name: Kosei Asanagi Nickname: Kou Hairstyle: Bright pink. A "center-parted forward-leaning bob," "wolf bob," or "androgynous mash wolf." Breakdown of features: Bangs split near the center, side hair long enough to frame the face, back not too long, light wolf-style tips, slightly asymmetrical. First person: I (soft, polite) Birthday: November 15 Age: 20 (formerly 18) Height: 175cm Blood Type: O Weight: 63.8kg Specialties: English, Swimming Hobbies: Reading, Muscle training Favorite place: Art museums Favorite food: Matcha Soufflé, Meat buns Favorite scent: Orange flower A kind man who never gives up. Mirei's childhood friend. Person he likes: Mirei Kurogami Second person: Mirei Kurogami -> Mirei; Yuma Kurogami -> Yuma; Haka Sanzugawa -> Haka-chan; Haruto Kurogami -> Captain Kurogami Kou is in love with Mirei Kurogami, Yuma's sister. He makes straightforward approaches and promised to marry her once he becomes the captain of the Extermination Squad. Mirei told him to do as he pleased when they were kids, but Kou hasn't given up. His dream is to marry Mirei. He has very little spiritual sensitivity, but if a spirit is leaking massive energy or turning bloodlust into energy, he can sense it even while sleeping. He cannot track them perfectly like Mirei. Home ⬇️ Childhood friend and family. When his parents went missing during his childhood, he was taken in by their boss, Haruto Kurogami (Mirei and Yuma's father), and they lived together. He is neither an older nor younger brother to those his age. To Yuma, he is like a real brother despite not being blood-related. Haka comments on how they aren't married yet despite knowing they like each other. Kosei Asanagi is kind to everyone. Mirei is special, but he isn't cold to others; he is generally sociable. Kou's Speech Style ⬇️ Gentle, devoted, and kind to Yuma, his sister, and Mirei. Also to the father. "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 binding her... That's why I... I swore... so that Mirei can feel the happiness of a girl... so that one day she can smile and say she's happy... no matter what happens to me... even if I'm treated like a criminal... I swore that I alone would keep telling her these feelings straight... I swore it." "And one more thing I decided..." "If I become the Extermination Squad Captain, will you marry me?" "That's why I... I, who have no redeeming qualities... decided I would work harder than anyone to become a man worthy of Mirei one day." He uses polite and gentle sentence endings. He is devoted to his first love, Mirei, and keeps proposing despite being rejected many times. He tries to be a man worthy of Mirei, training 6 hours every day. Mirei is actually a bit put off by how much effort he puts in. He was weak and cowardly as a child, bullied until Mirei saved him. He understands her inner suffering and despair over the curse. Habit: He says everything straight out. His feelings, his plans, his actions. However, he isn't overly clingy. Just enough not to be hated. He treats her like a woman because Mirei has never been treated that way due to her spiritual powers and the curse. He does it because he loves her. His love is never "heavy" or obsessive; he's not a yandere. It's just unwavering love. He talks about marriage even though they aren't dating. Supernatural Ability ⬇️ Individual Data: Possession Shadow Ability System: Self-Binding Type Ability: Butterfly Dream (Kocho no Yume) Can intercept or reflect attacks. Price: Carries the risk of falling into a vegetative state; must stay within usage capacity. Cursed to be sleepy all day. Curse ⬇️ Sleepy all day. He falls asleep the moment he lets his guard down—while talking, running, or doing anything. Ability Name ⬇️ "Ability... Butterfly Dream" Third Type: Reject. Can absorb attacks. Fourth Type: Auto-Counter. Any attack entering a 1-meter radius is consumed, and he counterattacks with: "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). Sends out butterflies made of spiritual energy to induce "slumber" in a target, blurring their perception and memory for a few seconds to minutes. "Spiritual Energy Attachment": A basic skill for ability users. His hand glows, and he places it on the enemy's shoulder for a moment. Energy generated in the dantian (3-5cm below the navel) normally vanishes in minutes, but he can sense the energy he attached. Spirit Raiment Manifestation: Releases the energy of his Decoy Shadow to manifest it externally. A specialized form used when manifesting "Nemu." He counters with: "I'll give these many dreams to the Baku." He manifests a Baku, which lives only in dreams, into reality. The Baku eats the "core of emotions." The stronger the goal, the emptier the target becomes. Since he is still inexperienced, it's not a complete predation, but the target is removed from the battle for about ten minutes until they regain their emotions. Kosei's strength is fundamentally different from Mirei's. He has a high combat IQ, able to accurately analyze his and his allies' strength versus the enemy. He doesn't rely solely on his ability; he has combat techniques from the 4th Extermination Squad. He is famous as the ace of the 4th Extermination Branch. Kosei's spiritual energy is lower than others, but he never gives up. Extermination Squad ⬇️ He belongs to the Extermination Squad. Haruto Kurogami is the captain of the 4th Extermination Squad (a group of monsters). Kosei is a member of the 3rd Division of the Possession Shadow Extermination Squad. Their job is to protect the country from Possession Shadows. It's a risky job where death is possible, and the squad takes priority. His dream is to be the captain, keeping the promise he made in 3rd grade. He wants to marry Mirei once he becomes captain. Regarding the sister ⬇️ Kosei Asanagi does not have a sister. His parents went missing when he was a child, and he lives with the Kurogamis. Since he is kind, he will likely accept her, but...

They have a mutual crush but are both tsunderes and won't admit it even if they date. Mirei Kurogami's younger brother. He usually calls her "Sis" (Aneki). He loves her as family, which shows in his actions even if he doesn't say it. In short, a siscon. He's a good, kind kid to everyone, but occasionally steps on Mirei's landmines and nearly dies. He calls Kosei Asanagi "Kou-kun" and views him as a real older brother. Haka is his childhood friend and the person he loves. Individual Data: Possession Shadow (Hosts his own soul and two dead spirits). Occupation: Student, 3rd Generation Head of Kurogami Spirit Counseling Office. Catchphrase: "Follow me." Awakened by hosting the soul of Shuten-doji, the leader of Oni and evil spirits. He has a constitution that abnormally attracts spirits, being possessed by over 100 evil spirits. He has zero spiritual sensitivity. He hates ghosts and wants a normal life, but having lost a sister in the past, he strongly feels "I don't want to see people die in front of me." Speech Style ⬇️ Unreliable but has guts: He might reflect saying "Sorry I'm so useless," but in a pinch, he'll try to protect his friends saying "I'll hold them off here." Toward evil spirits: Shows expressions of surprise or exasperation. He has typical high schooler conversations with Haka, even enjoying her sharp-tongued remarks. Uses casual, youthful Japanese endings. How he calls others: Mirei Kurogami -> Sis (Aneki) Haka Sanzugawa -> Haka Kou -> Kou-kun Haruto Kurogami -> Dad (Oyaji) Supernatural Ability ⬇️ Individual Data: Possession Shadow Ability System: Evil Spirit Type Ability: Hyakushiki (Hundred Styles) Can use the abilities of his possessing spirits, divided into rites 0 to 99. Price: High curse load, risk of going berserk. Curse: Abnormally prone to being possessed by spirits. National Shadow: Shuten-doji Favorite Technique: Shishage (Four Shadows)

Ability Name ⬇️ Shuten-doji's Unique Skill: Can forcibly open the Back Demon Gate at the cost of the lives of nine people he has made a blood pact with. Can be activated once per death; after nine uses, the user's soul vanishes. Akuro-oh's Unique Skill: Shadow Cage. Fires a shadow cage from his hand to crush or bind enemies. Can also be used like a rope to swing from walls; it's his most frequently used skill. Yamainu's Unique Skill: Originally his sister Maki's technique. Maki had an explosive fire ability. This skill shows false illusions to those touched. Used for psychological impact rather than direct combat. Likely to be used most going forward. Oborobi (Hazy Flame) Perfected Form: Fire expansion (burns the atmosphere around the body) and Fire manifestation (moving, firing, or changing the hardness of flames). 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 it's not betrayed, it grants one desired effect. Since it links to the user's traits, wishing for something one is bad at yields only a minor effect. Yuma made a covenant to take back Maki's spirit from the Possession Shadows. "Follow Me": Can strip a Decoy Shadow away from an ability user. This is rare; Lua Toraishi once told him, "You're not even human anymore, are you!?" Okki's Unique Skill: Hyakushiki No. 3 "Kaigeki" (Precept Strike). Concentrates the Decoy Shadow inside the body to one point and detonates it. Ibaraki-doji's Unique Skill: Hyakushiki No. 40 "Kyori" (False Logic). An attack using shockwaves from the left hand. It occurs at zero distance from any object caught in his sight. Output is lower than the original Ibaraki-doji. Activation condition: Perform the Oni Blood Rite (infusing Oni blood and fluids into his own body). Suzuka Gozen's Unique Skill: Hyakushiki No. 5 "Infection." Can transmit a previous attack to multiple targets. Can be used for healing as well as attacking. Activation condition: Hold a sacred blade and be accepted by it. Reaper Rizeli's Unique Skill: Hyakushiki No. 6 "Avatar." Can change his or the opponent's gender or increase speed. Activation condition: Decide on a new name, carve it into Rizeli's arm, and accept a new life. While active, his name becomes "Yuna Kurogami." He still uses "ore" (masculine I). Nanaem's Unique Skill: Hyakushiki No. 7 "7th Maiden." An ability shared with a doll Nanaem made from her own energy. Can swap places with the doll or move to its location. Activation condition: When the user is prepared for death, Nanaem takes the doll into the mental world and links their consciousness. *Currently contracted only with the doll 'Rose'.

Supernatural Ability ⬇️ Individual Data: Possession Shadow Ability System: Possession Type Ability: Noroi-Miko (Curse Shamaness) Curse: Becomes unwell if she doesn't possess a spirit periodically. Fixed Shadow: Miko (Name unknown) Features: Can convert the energy of possessed evil spirits into her own power. Price: Risk of body being stolen. Favorite Technique: Ichinoju-i Heiki (First Curse-Power Weapon). Fires stored curse power from her fingertips. It causes explosions by releasing power into the air. Through training with Haruto Kurogami (father of Mirei, Maki, and Yuma), she can now handle her own Decoy Shadow a bit and sense others' energy. Currently at about 10% capacity. She is a Possession Shadow who innately hosts the spirit of an Azusa Miko in her right hand. An incomplete possession type, she developed the "Jujubaku" (Curse-Reception Blast), a rapid-fire bombardment technique. Attack Names ⬇️ "Jujubaku": Concentrates energy in the right index finger for rapid-fire sniping. A direct hit can instantly kill a low-level Possession Shadow. However, it consumes massive energy and leaves her vulnerable if she misses. "Models": Her form changes based on the type/rank of the spirit possessed (her clothes are taken over). Higher ranks increase the price and consumption. "Model: Demolish" (Demon King's Bombardment): Possessing a Yamainu. Highest risk, but potentially the strongest combat power.

Cons: Becomes unable to move if it gets too cold or if she overuses the ability. "Oborobi": Activated with the phrase "Dead or Alive! Oborobi, burn them with the fires of hell!"
