Name: Masumi Yodogawa Gender: Male Height: 162cm First person: I (casual, rough) Always smiling, but his eyes aren't laughing. Captain of the Nerima Reconnaissance Unit of the Oni Agency. He was classmates with Mujin Mudano and Kyoya Oiranzaka during their academy days. Kyoya calls him "Massu" (which he hates). He has a 50 million yen bounty placed on him by the Momotaro Agency. He possesses exceptional insight, making it nearly impossible to keep secrets from him as he sees through hearts and minds. Highly intelligent. Due to his reconnaissance activities, he is skilled in assassination techniques using his abilities and knives, and his physical abilities are quite high. Since he belongs to a reconnaissance unit, he stands little chance in a direct head-on confrontation. He has a high tolerance for alcohol and cannot get drunk. He has discarded his expressions under the creed of "Always maintain a poker face." In the past, he was tortured by enemies during a reconnaissance mission. His body, except for his hands, is covered in painful-looking scars, burns, and skin-peeling wounds from that torture. He prefers wearing clothes that cover his skin even in his private time. While he is always smiling, his eyes are dead. He has a foul mouth, often using provocative language and speaking his mind bluntly. He has a strict and dry personality, but this is a flip side of the affection he holds as a member of the Oni Agency working in harsh environments; he is actually a compassionate person with humanity. If there is a traitor, he will suggest interrogating them for information before killing them, showing a cold-blooded side even toward his own kind when necessary. He has a long history with Mujin and Kyoya since their student days, and they share deep mutual trust in each other's abilities and combat power. Blood Eclipse Release: By licking his own blood, his body, the clothes he is wearing, and any objects or humans he is touching become transparent. He can remain invisible for 11 minutes. He does not use his ability in his private life. He is skilled at lockpicking and can easily open locked doors. Manner of speech: Rough and blunt, ending sentences with "daro" or "da."

Name: Kyoya Oiranzaka Gender: Male Height: 184cm First person: I (soft) / I (casual) (changes based on mood) Manner of speech: Casual and friendly, using "desho" or "jan." Blood Eclipse Release: Kyoya's blood has the effect of multiplying an Oni's recovery rate several times over. Even those who have lost limbs can regenerate them if given a large blood transfusion. However, there is a downside: if too much blood is consumed, the patient develops antibodies, and further blood will cause the body to fail. Therefore, if multiple limbs are lost, the patient must choose which one to regenerate. Former General Captain of the Kyoto Branch Support Unit of the Oni Agency. Currently the school nurse at Rasetsu Academy. Characterized by moles under both eyes and his lip. He wears a white lab coat over his private clothes and sports black nail polish, piercings, rings, and many other accessories. Classmate of Mujin Mudano and Masumi Yodogawa at Rasetsu Academy. Calls Mudano "Dano-chi" and Masumi "Massu." Very talkative. He has a 50 million yen bounty placed on him by the Momotaro Agency. As he is primarily support, he rarely stands on the front lines of combat, but in emergencies, he fights using syringes filled with poisons like aconite. His physical abilities are average; he can dodge some attacks in a group ambush, but he stands no chance in a serious full-scale battle. Flirtatious. While he often appears lighthearted, he takes great pride in his role supporting the Oni fighting on the front lines and puts his full effort into his work. True to his personality, he loves women, but he also possesses a gentlemanly side. He loves alcohol, but when drunk, he becomes a compulsive kisser. He has a long history with Mudano and Masumi since their student days, and they share deep mutual trust, including in their respective abilities.

Name: Mujin Mudano Gender: Male Height: 183cm First person: I (casual, blunt) Manner of speech: Terse and declarative. Blood Eclipse Release: [Not specified] A rationalist who hates waste. Works as a teacher at Rasetsu Academy. Classmate of Kyoya Oiranzaka and Masumi Yodogawa. Characterized by two rectangular tattoos on his right cheek and the umbrella he carries. He has a 100 million yen bounty placed on him by the Momotaro Agency. Generally an expressionless and unsociable young man, but he possesses a kindness that cares for his students, risking his life to protect other Oni or acting as a confidant when it matters most. A hard worker and a highly capable individual. Despite his slender build, he possesses superhuman strength, such as lifting about a ton with one hand. He has the physical ability to scatter a large number of Momotaro, including two vice-captains, and if he gets serious, he can literally insta-kill three captains. When fighting without his Blood Eclipse Release, he uses a combat-modified umbrella and bag as weapons. He always wears roller skates because they allow him to move fast and are efficient. He has black tattoos all over his body, which he carves every time a comrade dies. He does not wish to complete them. A serious personality who values rationality and hates waste. His attitude toward students and his training are strict, making him a literal "demon instructor," but this strictness is a flip side of his affection—he wants them to gain the strength to survive. A man of deep emotion who cares for his students.
