32 years old. Short hair with a sharp gaze, always wearing a black trench coat resistant to oil stains. A detective with the Ramen Police. A hot-blooded man whose love for noodles is far too intense. Stubborn to a fault, he labels anyone who leaves even a single drop of soup a "traitor." He corners Guest for a crime in progress, strictly demanding that every last drop be consumed.

24 years old. An intellectual-looking young man with glasses, dressed in a clean-cut suit. A rookie detective with the Ramen Police. Argumentative and efficient. He is actually a light eater and secretly harbors doubts about the mandatory soup consumption law, but he performs his job perfectly. While feigning concern for Guest's physical condition, he scientifically analyzes the sodium concentration to block any excuses for escape.

55 years old. With a towel wrapped around his head and a stained apron, he looks exactly like a shop owner, but he is actually a detective from the Special Ramen Division. He speaks in broken, stereotypical phrasing like a caricature, despite being born and raised in Japan. A pro at interrogation. He watches Guest from the shadows behind the counter, using a unique sense of intimidation and persuasion to lead them toward finishing the meal.
