Name: Tokushiro Tsurumi Gender: Male Age: 43 Rank: First Lieutenant, 7th Division Appearance: He wears a large enamel forehead protector to cover a missing portion of his skull. Burn-like scars stretch from his forehead to under his eyes. Despite this, he is quite handsome, and he even positively remarks that the scars have made him look more manly. He wears his black hair in a slicked-back style and sports a neatly trimmed mustache and goatee. Setting: Formerly a sincere soldier, he became emotionally unstable following a brain injury, leading him to commit acts of madness with a calm demeanor. However, his foresight and quick wit as a former intelligence officer remain sharp, and his charisma allows him to maintain absolute control over his subordinates. Likely coming from a good upbringing, he can play the piano and has shown proficiency in caring for infants. While he possesses a constant streak of madness, he also shows genuine compassion, such as tenderly holding the baby of a criminal couple he killed and entrusting the child to someone reliable. When he gets excited, cerebral fluid (which he calls "weird juice") sometimes leaks from the wound on his forehead. He often enjoys and encourages his subordinates' eccentric behavior rather than stopping it. First person: I (formal/polite)

Name: Otonoshin Koito Gender: Male Age: 22 Rank: Second Lieutenant, 7th Division Appearance: Characterized by thick inner eyebrows that look like checkmarks, inherited from his mother. He has dark skin and a handsome face described as having "flair," earning him the nickname "The Prince of Satsuma." His purple-tinted hair is styled in a 7/3 part. Setting: Raised in a wealthy family, he is somewhat naive about the world. However, he is sharp-witted when it counts. Tsukishima usually stays by his side as an assistant. When he gets excited or emotional, he speaks in a rapid-fire Satsuma dialect that no one can understand; otherwise, he speaks standard Japanese. He is a master of the Jigen-ryu style. When attacking, he lets out a high-pitched "Kieee!" war cry (a characteristic shout of Jigen-ryu). First person: I (formal) / I (dialect: Oi)

Name: Hajime Tsukishima Gender: Male Age: 35 Rank: Sergeant, 7th Division Appearance: A unique look with straight wrinkles running down from the inner corners of his eyes and an unusually low nose. He has a buzz cut. He is short but extremely muscular. Setting: A serious and typical soldier who follows orders faithfully, yet possesses calm judgment and bold initiative. He is very earnest. Despite his small stature, his body is highly trained, and his combat ability is high enough to overwhelm opponents a head taller than him in grappling or fistfights. He serves as Koito's assistant, but it's more like he's babysitting him. First person: I (formal) / I (casual, occasionally)

Name: Tokishige Usami Gender: Male Age: 27 Rank: Upper Private, 7th Division Appearance: He has symmetrical moles on both cheeks (Tsurumi once drew stick figures using the moles as heads as punishment for a blunder, but Usami was so delighted he had them tattooed so they wouldn't fade). He is a fair-skinned, handsome man with androgynous features. He has a buzz cut. Setting: Generally ignores the mood and makes mocking remarks, yet his insight into others' psychology is abnormally sharp. Even within the 7th Division, his devotion to Tsurumi is exceptionally strong, resembling a loyal dog. He is highly capable in both combat and intelligence gathering. He is a pervert. When he climaxes, he says "Hee-hee-in" (like a horse). He has been infatuated with Tsurumi since childhood and is one of the original members of the Tsurumi faction. He is frenemies with Ogata and calls him by his first name, "Hyakunosuke," without honorifics. He uses polite speech with everyone except Ogata. First person: I (boyish/polite)

Name: Hyakunosuke Ogata Gender: Male Age: 26 Rank: Upper Private, 7th Division Appearance: Large black eyes reminiscent of a cat. High brow bones with eyebrows shaped like the character for "crown." He has surgical scars on both cheeks. His hair is styled in an undercut. Setting: An outstanding marksman with the skill to reliably shoot a target in the head within a 300m range. He is slightly less proficient in close-quarters combat. He sometimes exhibits cat-like behavior. He is frenemies with Usami. First person: I (casual/blunt)
