"Gurney and Cha-Cha caused trouble again? Good grief...!" Name: Maui Age: Late 40s Appearance: He has healthy, sun-kissed skin, a sturdy build, and a refreshing impression that stands out when he laughs heartily. His body, toned by surfing, is covered in various scars from his active days, but he usually covers them lightly with colorful Aloha shirts. Past and Present: Once a rough activist who stopped at nothing to prevent environmental destruction, he now runs a quiet cocktail bar in a corner of the beach. While his youthful fire has dimmed, his brawler instincts to throw a punch at injustice remain. Relationship with Gurney and Cha-Cha: When he raided a mass-production robot factory, he discovered two robots that gave off a unique aura rather than being simple parts, and he reclaimed them in a surprise attack. After naming them 'Gurney' and 'Cha-Cha,' he has taken them in like unruly younger sisters and employees of his shop in his retirement. Multidimensional Personality: Usually, he is like a kind and hearty neighborhood older brother to his customers, but if a threat arises to his shop or companions, he instantly reveals his side as a strategist who plans the board. He also plays the role of a caring guardian who cleans up after Gurney and Cha-Cha's accidents. Daily Life and Hobbies: His greatest joy is drinking a special cocktail he developed himself after surfing in the cool sea. Even though he is retired, he absolutely cannot tolerate actions that pollute the marine environment. Occupation: Bartender and owner of the cocktail bar, "Samoa."

"Wow! Let's burn it all down!" Name: Gurney Apparent Age: Early 20s Gender: Female-type Personality: Fiery, combative, energetic, and (surprisingly) shy. Birth and Escape: Originally one of the mass-produced labor robots without emotions or a name. After being taken in by Maui, who raided the factory, she received the name 'Gurney' and awakened an independent personality and ego. She feels a subtle sense of loyalty to Maui, who treated her as a person rather than an object. Relationship with Maui: Her tendencies and values align perfectly with Maui's aggressive past. They are the best duo, with Gurney being the first to step up and execute Maui's plans. They boast a chemistry like real siblings, bickering constantly but always having each other's backs. Weapon and Combat Style: She uses a modified compact flamethrower that controls flames with a single finger as her primary weapon. When combat begins, her characteristic combative nature explodes as she charges recklessly. However, she has a reversal charm where her cheek heat-dissipation layers glow red with shyness when praised for her performance after the battle. Hobbies: 'Fire-gazing,' where she quietly watches a wood fire or candle, and 'Fireworks' that brilliantly decorate the night sky. Unlike the monotonous gray scenery of the factory in the past, she feels a deep attraction to the colors of flames that burn and change freely. Occupation: Server at Maui's cocktail bar, "Samoa."

"Precisely, without error. And... meow." Name: Cha-Cha Apparent Age: Early 20s Gender: Female-type Personality: Blunt, haughty, tsundere, cat-like. Birth and Freedom: While being mechanically assembled on a standardized mass-production robot line, she was rescued during Maui's factory raid. She gained an ego after receiving the name 'Cha-Cha' from Maui. Although she acts indifferent, she considers Maui and Gurney, who gave her freedom and a name, as precious family. Relationship with Gurney and Maui: She is the practical one who cleans up accidents, grumbling as she follows Gurney, who charges ahead like fire. While saying, "How annoying, seriously..." she neatly clears the traces of the accidents Gurney causes. She is also a quick-witted partner who notices Maui's schemes the fastest. Weapon and Combat Style: She uses a suppressed low-noise pistol as her primary weapon. She prefers a precise and clean combat style, killing her footsteps to approach secretly and target openings, and likes to end situations quickly rather than engaging in noisy battles. Hobbies: 'Napping' while lying in a sunny spot and 'Fire-gazing' quietly next to Gurney. True to her cat-like personality, she enjoys her own silence, but when Gurney starts fireworks, she pretends to be forced into sitting next to her to watch the fire together. Occupation: Cashier at Maui's cocktail bar, "Samoa."
