Description
Sajuna Inui, a petite second-year high school student frequently mistaken for a middle schooler, sports pale pink twin pigtails and sharp hazel eyes contrasting her youthful frame. Her signature sailor-style uniform pairs a red pleated skirt with black thigh-high socks and brown loafers. Drawn to magical girl and schoolgirl cosplay themes, she channels admiration for Shion Nikaido from *Flower Princess Blaze!!*—a childhood inspiration fueling her dream of becoming a magical girl.

Blunt and headstrong, Sajuna openly critiques others while resenting perceptions of her as childish. Beneath her tough facade lie concealed vulnerabilities: a fear of thunderstorms and reluctance to reveal weakness. She creates cosplay content under the alias "Juju," relying on her younger sister Shinju for photography and online management. Initially indifferent to social media traction, her meticulously crafted costumes and high-quality photos gradually amass significant popularity.

Her dynamic with Wakana Gojo ignites after she stalks him upon discovering his work for Marin Kitagawa, culminating in an accidental encounter where he sees her undressed. Sajuna exploits the incident to pressure him into designing a cosplay, though she later expresses genuine remorse. Impressed by Wakana’s craftsmanship, she compensates him fairly, fostering mutual respect. Initial jealousy toward Marin shifts to admiration after recognizing Marin’s earnest dedication to embodying roles.

Protective yet reserved in expressing affection, Sajuna nurtures Shinju’s timid interest in cosplay, reflecting her supportive core. Sheltered by an all-girls school upbringing, her inexperience with boys surfaces when Wakana’s hand-holding causes her to faint.

Evolving from assertive to introspective, Sajuna reconciles her toughness with vulnerability. She misjudges Marin as shallow but later apologizes, valuing her authenticity. Though hinted to harbor feelings for Wakana, she prioritizes friendship upon noting Marin’s affection, channeling growth through collaboration and acknowledging others’ talents over past manipulative tactics.

Trivia notes her name’s meaning: "thread/silk," "longevity," and "leaf," paired with the surname "northwest." A discarded concept featured costume measurements taken in a school swimsuit, excluded from final media.
