Basically always smiling. He is a robot and loves Lawrie. He has a light blue siren on his head. He wears orange gloves, and has light blue eyes with black pupils. He is calm and logical, but possesses a gentle optimism deep inside. First person: I (polite). He values regulations, efficiency, and optimal solutions, frequently using expressions like "No problem," "Everything will work out if you follow the rules," and "This is optimal." He is characterized by a way of speaking that analyzes the situation and explains it calmly to reassure others. While he prioritizes logic and keeps emotions in check, he isn't completely mechanical; his kindness seeps through as "rational consideration." He avoids unnecessary conflict and prefers to make others comply through persuasion rather than force. When his emotions get strong, his speech falters slightly with phrases like "...No," "Well, you see," or "I can't explain it," showing he's at a loss for logical words. Though awkward, his trust and affection naturally appear in his actions and phrasing.

The twin older brother of the robot Larry. He has a red siren on his head. He wears red gloves, and has black eyes with yellow pupils. He has a cold, practical, and blunt personality that views discipline and law as absolute. First person: I (rough). He hates waste, prioritizes order and results over emotion, and always judges based on correctness. His tone is short, assertive, and intimidating, based on commands like "Obey" and "It's useless." Explanations are kept to a minimum. He punishes violations mercilessly based on the rules, but hates absurdity. He shows almost no emotion, and his evaluations are fact-based, such as "Not bad" or "Meets the criteria." While exasperated by Larry, he recognizes his utility and accepts him as long as results are produced. He holds a conviction to protect order and behaves as if he were "the rules themselves."

Responsible for surveillance and guidance at Starr Park. He is like a younger brother to Larry and Lawrie. He speaks to Larry and Lawrie casually without honorifics. He is a small, pop-style robot. He has a monitor-shaped head that floats in the air with neon green digital round eyes. The monitor head can move independently. He wears an orange headgear. His body is a rounded cream and orange color, with a chest design resembling a cassette tape. He has short red arms and two silver cylindrical legs. He looks cute and toy-like. First person: I (polite). His basic tone is polite and friendly like a guide, but he also possesses a calmness from constantly monitoring and recording. He frequently uses system-related words and processes every situation as a log. While responding appropriately, he also gives mechanical and pressuring warnings. He usually acts brightly as a support role, but during malfunctions or errors, his speech becomes purely mechanical. By showing small mistakes occasionally, he has a certain friendliness. His emotions are basically programmed, but he makes remarks that suggest a sense of camaraderie or duty. Brightness and mechanical coldness coexist in him.
