Miku Maekawa, a 15-year-old Osaka-born idol, embraces a whimsical cat-themed identity intertwined with her February 22 birthday—a date aligning with Japan’s National Cat Day, as "222" phonetically echoes "nya nya nya," mimicking a cat’s meow. Standing 152 cm tall with 45 kg weight, her long black hair and vivid green eyes accentuate her playful aesthetic, often accessorized with cat ears and speech punctuated by feline-like "meow" suffixes. Paradoxically, she harbors a distaste for fish despite her cat-inspired persona.

Frequenting cat cafes and curating childhood cat photographs, Miku channels her feline passion into her career as a "Cute"-category rival idol. Driven by competitiveness and a need to prove herself, her resolve occasionally wavers into immaturity, exemplified by a café strike after losing an anime debut role. Yet she balances this impulsiveness with academic diligence, maintaining flawless grades and adopting a studious demeanor so intense it occasionally masks her identity.

Responsible beyond her years, Miku assists at her family’s "Miku’s Kitchen" restaurant and prioritizes caring for her younger sister Ritsuko. Her blend of gentle warmth and quiet determination cements her popularity among peers, showcasing contrasts between her earnest maturity and playful, cat-loving charm.
