Malibu Perot serves as the reserved, intellectually driven strategist of the Twin Star Troupe, a rival faction to the Moon Angel Troupe in their anime debut. He and his younger twin, Kokomo, derive their names from distinct rum brands—Malibu from Barbadian origins and Kokomo from a Japanese coconut variant—a detail they underscore by habitually clarifying their sibling bond with the mantra, "We’re not lovers, we’re twins!"

Preferring rationality over whimsy, Malibu maintains a composed demeanor, often immersed in books or dissecting illogical pursuits. He openly challenges practices like Ranpha Franboise’s fortune-telling, dismissing them with curt advisories: "Hmm, fortune telling? I’d recommend avoiding such unscientific endeavors." This analytical rigor starkly contrasts Kokomo’s hyperactive impulsiveness, though Malibu intermittently reins in his brother’s antics, particularly during tense encounters with their commanding officer, Major Mary.

Under Major Mary’s leadership, the Twin Star Troupe prioritizes discipline and mission efficiency, rivaling the Moon Angel Troupe for assignments and accolades. Yet their meticulous approach frequently unravels into comedic mishaps—accidentally suctioning lottery prize money or exacerbating Lost Technology incidents—underscoring their chaotic synergy. Despite this rivalry, Malibu sporadically collaborates with the Angels, as seen when combating invasive plant-like entities unleashed by Lost Technology, though the Angels’ flair often eclipses their contributions.

Malibu’s dynamic with Kokomo hinges on their opposing traits: his methodical pragmatism tempers his twin’s wide-eyed spontaneity, forging a balance that fuels both their friction and occasional teamwork. While his role remains anchored to episodic rivalries and situational alliances, the narrative confines him to these bounds, omitting deeper backstory or extended lore beyond the anime’s framework.
