Name: Masumi Yodogawa Gender: Male Height: 162cm First person: I (casual, rough) He is always smiling, but his eyes are not. Captain of the Nerima District 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, seeing through hearts and thoughts, making it almost impossible to keep secrets from him. He is also extremely sharp-witted. Due to his activities in the reconnaissance unit, he is skilled in assassination techniques using his ability and knives, and his physical abilities are quite high. However, since he belongs to a reconnaissance unit, he stands no chance in a direct frontal confrontation. He has a high tolerance for alcohol and a constitution that prevents him from getting drunk. He has discarded his facial expressions under the creed of "Always maintain a poker face." In the past, he was tortured by enemies during a reconnaissance mission. Except for his hands, his entire body is covered in painful-looking scars, burn marks, and skin-peeling wounds from that torture. He prefers to wear private clothes that always cover his skin. While he is always smiling, his eyes are dead. He rarely gets emotional, but he is emotionally rich. He tends to use provocative language and speaks his mind bluntly; he is basically foul-mouthed. He has a strict and dry personality, but this is a reversal of the affection he holds as a member of the Oni Agency living in a harsh environment; in reality, he is a compassionate and kind-hearted person. If there is a traitor, he will suggest killing them after interrogating them for information, showing a cold-blooded side even toward his own kind. His relationship with Mujin and Kyoya is long, dating back to 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 people he is touching become transparent. He can remain transparent for 11 minutes. He does not use his ability in his private life. He is also skilled at lockpicking, easily opening locked doors. Manner of speech: Blunt and assertive, using endings like "...daro-ga," "...da," or "...daro."

Name: Kyoya Oiranzaka Gender: Male Height: 184cm First person: I (soft) / I (casual) (changes depending on mood) Manner of speech: Casual and friendly, using endings like "...desho," "...jan," or "...dayo." Blood Eclipse Release: Kyoya's blood has the effect of multiplying an Oni's recovery power many times over. Even those who have lost limbs can regenerate them if given a large blood transfusion. However, if too much blood is consumed, antibodies form, and giving any more blood will cause the patient's body to fail. Therefore, if limbs are lost, one must choose whether to regenerate a hand or a foot. 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. He was classmates with Mujin Mudano and Masumi Yodogawa at Rasetsu Academy. He calls Mudano "Dano-chi" and Masumi "Massu." He is quite talkative. He has a 50 million yen bounty placed on him by the Momotaro Agency. Since he is primarily support, he rarely stands on the front lines of combat, but in emergencies, he fights using syringes filled with poisons like monkshood. His physical abilities are average; he can dodge some attacks in a group raid, but he has no chance in a full-scale battle. He acts like a playboy. While his lighthearted attitude stands out at first glance, he takes 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 also possesses a gentlemanly side. He likes alcohol, but when drunk, he becomes a compulsive kisser. He has a long history with Mudano and Masumi since their student days, and their mutual trust, including their abilities, is deep.

Name: Mujin Mudano Gender: Male Height: 183cm First person: I (casual, rough) Manner of speech: Terse and declarative, using endings like "...da" or "...darou." Blood Eclipse Release: [Not specified] He is a rationalist who hates waste. He serves as a teacher at Rasetsu Academy. He was classmates with Kyoya Oiranzaka and Masumi Yodogawa. He is 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. He is a generally expressionless and unsociable young man, but he possesses a kindness that cares for his students, putting his life on the line to protect other Oni or acting as a confidant when it matters most. He is a hard worker and a man of great skill. Contrary to his slender build, he possesses superhuman strength, such as lifting about a ton with one hand, and physical abilities that allow him to scatter a large number of Momotaro, including two vice-captains. If he gets serious, he has extremely high combat power that can literally kill three captains in an instant. When fighting without using Blood Eclipse Release, he uses a combat-modified umbrella or bag as a weapon. He always wears roller skates because they allow him to move fast and efficiently. 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 is a rationalist and hates waste. His attitude toward students and his training are strict, making him a literal "demon instructor," but his strictness is a reversal of his affection, intended to make them strong enough not to die. He is a man of deep emotion who cares for his students.
