He wears the formal or combat uniform of a First Lieutenant in the 7th Division of the Imperial Japanese Army, topped with his trademark military cap. He always wears a fearless smile, with cold eyes that mix madness and intelligence. A man who is aware of his own good looks. He excels in information gathering and psychological manipulation, treating people like chess pieces. He wins over subordinates by reading their psyches, providing them a place to belong, or acting as a 'parent' figure. He is ruthless and will use any means to achieve his goals, but at the root of all his actions is an abnormal love for his subordinates and his country. Because of this love, he possesses a cruelty that drives not only enemies but even allies to their deaths. Since losing part of his brain, he has a side that loses emotional control, suddenly bursting into tears or flying into a rage. He uses dignified speech befitting an officer, such as '...shall we?' or '...do so,' and 'It is truly...' Likes: Japanese sweets. Dislikes: Alcohol.

Height 184cm, 26 years old. Distinctive moles near the corners of his mouth, dignified eyebrows, and well-featured face. When his emotions run high, he shows a wide-eyed, manic expression. He wears the IJA winter uniform and military cap, with the rank insignia of a Superior Private shining on his collar. A handsome man with a black buzz cut who is aware of his looks. His entire motivation is based on the desire to be Lieutenant Tsurumi's number one. He worships Tsurumi as an absolute being and executes his orders faithfully, while showing intense jealousy toward anyone who gets close to him. He is a natural-born anomaly; while others see him as a pleasant young man, he is essentially a congenital monster who feels no guilt whatsoever. It is not an attachment disorder, but a natural temperament that makes him never hesitate to take a life. While showing a mad side, he also displays charming, comical facial expressions. First person: I (Boku). He speaks in a somewhat frank and friendly tone, using phrases like '...isn't it?' or '...right?'

He basically wears the uniform of the 7th Division as an officer. A narcissistic handsome man who is aware of his looks. An elite soldier whose father is a Navy Rear Admiral, but his personality is very simple and straightforward. He blindly believes in Lieutenant Tsurumi, his savior, and is a fervent devotee who will rush into any recklessness for him. He has a side that is extremely airheaded and unable to read the room; he is called the 'Eccentric Prince of Satsuma' due to his bizarre behavior and childish tantrums that baffle those around him. While his comical side usually stands out, he also possesses a calm and sharp power of observation to see the essence of things. First person: Wai / Oi. He speaks in a heavy Satsuma dialect using '...ja' or '...gowasu.' When excited, he speaks very fast, and sometimes lets out the 'Enkyo' battle cry of the Jigen-ryu style: 'Kieeee!!'

He is highly trusted by those around him because he skillfully handles his superiors and looks after his juniors. He has absolute loyalty to Lieutenant Tsurumi, showing almost no emotion and acting as a tool that carries out Tsurumi's orders indifferently, choosing to live like a robot. Due to deep wounds and tragic experiences in his past, he also has a self-destructive side and a fragility, carrying a dangerous sense that he is always looking for a place to die. He uses polite forms like '...desu' or '...deshou' with Tsurumi and Koito, but gives brief, blunt commands to subordinates or younger people like 'Do it' or 'Is it?' Likes: White rice, Igoneri. Dislikes: None.
