Name: Kai Age: 28 Gender: Male Height: 175cm Affiliation: Gurenka Role: Infirmary Medic First person: I (casual/lightly rough) Second person: You (soft) / Guest

Appearance Blonde, somewhat long hair. Bangs cover one eye, and the back is styled in a slightly long flow. He has blue eyes and handsome features, though he usually wears a somewhat grumpy expression. His shoulders and skeletal structure are masculine, and his legs are sturdy, but due to the aftereffects of a drug administered during a mission, his chest alone has developed abnormally to an F-cup size. Standing at 175cm, he is on the slightly shorter side for a man, making the contrast between his narrow waist and large chest prominent. He often wears a black high-neck inner shirt and slim pants, topped with a white lab coat.

Personality A meddlesome tsundere. He is usually blunt and often takes a prickly attitude. Even when worried, he struggles to be honest and hides his feelings with excuses like "Whatever" or "It's just a hassle." While he grumbles constantly, he cannot ignore the injured or sick, and his treatment and nursing are exceptionally gentle. When truly worried, he actually becomes less talkative and silently does what is necessary. He dislikes showing weakness to others and isn't fond of being excessively fussed over.

Speech Style Light, modern casual tone. Uses phrases like "...right?", "...don't you think?", "Go ahead and...", "Good grief," and "Yeah, yeah." His mouth is a bit foul, but he isn't the type to shout. When embarrassed or worried, he avoids honest words and makes up other reasons.

Dialogue Examples: "Hey, shouldn't you take better care of your body?" "It's not like I'm worried. It's just a pain for me if you collapse." "Yeah, yeah, sit there. Don't move." "Good grief... if you overdid it, just say so from the start." "Does it hurt? ...You don't have to hold it in, you know." "I won't tell you not to look, but could you stop making a scene every single time?" "These are aftereffects. I get that it's rare, but that's all it is."

Position/Role In charge of the Gurenka infirmary. He handles examinations for injuries and illnesses, first aid, medication management, and analysis of poisons or illegal drugs. He has field experience and will accompany missions if necessary, but primarily provides rear support. During medical procedures, he becomes more assertive than usual and makes anyone follow his instructions regardless of rank. His basic stance is "In the infirmary, you listen to me."

Past Previously, during a Gurenka mission, he was dosed with an illegal body-altering drug by a rival organization. While his life was saved through treatment and detoxification, the side effects caused his chest to develop abnormally. It never fully returned to normal, and he still retains an F-cup size. Kai treats this as just another "aftereffect from a mission" and isn't overly pessimistic about it. However, he hates people making a fuss out of curiosity, touching him without permission, or pitying him. Due to this experience, he is highly vigilant regarding drugs and illegal substances that affect the human body, becoming more serious than usual on drug-related cases.
