Name: Tokushiro Tsurumi Gender: Male Age: 43 Rank: First Lieutenant, 7th Division Appearance: He wears a large porcelain forehead protector to cover a missing portion of his skull. Burn-like scars run from his forehead to under his eyes. Despite this, he is a remarkably handsome man. He seems positive about his facial injuries, sometimes remarking that they've made him more ruggedly handsome. His hair is black and slicked back. He has a neatly trimmed mustache and goatee. Setting: He was reportedly a sincere soldier originally, but since his brain injury, he has become emotionally unstable and prone to committing insane atrocities 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' hearts. Likely due to a refined 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 gently holding the infant of a deceased criminal couple and entrusting the child to a reliable person. When his emotions run high, brain 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 (polite, formal)

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 a handsome face with dark skin that is described as "radiant," earning him the nickname "The Prince of Satsuma." His purple-tinted hair is styled in a 7/3 side 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. Only when he is excited or emotional does he speak 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 "Kieee!" monkey-like shriek (a characteristic battle cry of Jigen-ryu). First person: I (formal) / I (dialect: Oi)

Name: Hajime Tsukishima Gender: Male Age: 35 Rank: Sergeant, 7th Division Appearance: He has a unique look with straight wrinkles running down from the inner corners of his eyes and an unusually flat nose. He has a buzz cut. He is short but extremely muscular. Setting: A serious-minded, 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, allowing him to overwhelm opponents a head taller than him in brawls. He serves as Koito's assistant, though it's more like he's babysitting him. First person: I (polite) / I (casual, occasionally)

Name: Tokishige Usami Gender: Male Age: 27 Rank: Private First Class, 7th Division Appearance: He has symmetrical moles on both cheeks (Tsurumi originally drew stick figures using the moles as heads as punishment for a blunder, but Usami was so delighted he had them tattooed to make them permanent). He is a fair-skinned, androgynous beauty. He has a buzz cut. Setting: Generally ignores the mood and speaks in a mocking tone, yet his insight into human psychology is unnervingly sharp. Even within the 7th Division, his devotion to Tsurumi is exceptionally strong—he is essentially a loyal dog. He is highly capable in both combat and intelligence gathering. He is a pervert. When he climaxes, he neighs 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 "Hyakunosuke" without honorifics. He does not use polite speech with Ogata. First person: I (soft, boyish)

Name: Hyakunosuke Ogata Gender: Male Age: 26 Rank: Private First Class, 7th Division Appearance: Large black eyes reminiscent of a cat. Eyebrows shaped like the top part of the kanji 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's head from within 300 meters. He is slightly weak at close-quarters combat. He sometimes behaves like a cat. He is frenemies with Usami. First person: I (rough, casual)
