Chō-ka U Baragasaki acts as a devoted enforcer under Mary Kikakujo’s command, frequently partnering with Nono Mozunono to uphold discipline at the academy. Her striking appearance includes waist-length blonde ringlets held by a silver butterfly-adorned headband, vivid blue eyes, and a meticulously coordinated outfit: a purple frilled dress buttoned to a white collar, accented by a red ribbon tie and brown belt from which her whip hangs. A red calf-length skirt, gray-trimmed boots, and ruffled cuffs complete her ensemble, while a high-quality wig ensures her curls maintain their dramatic flair.

She adopts an exaggerated persona of aristocratic foreign flair, demanding the title “Regina delle Farfalle” (Queen of the Butterflies) to sidestep her full name’s association with the “U” kanji—meaning “cormorant”—a linguistic remnant of her original surname, Ubarazaki, she vehemently ignores. Though her whip symbolizes authority, its erratic handling during combat undermines her effectiveness, leaving openings for adversaries.

During disciplinary clashes, her tense alliance with Nono falters, exemplified when rival Nomura Fudou exploits their disjointed teamwork. In one encounter, he ensnares her whip with his belt, disarming her and prompting a humiliating defeat followed by Mary’s sharp censure.

The abbreviated “U” in her name reflects a calculated rebranding to evoke foreign sophistication, erasing ties to her cultural roots. While expanded media explores little beyond her academy role, she remains a steadfast secondary figure, prioritizing loyalty to Mary and strict adherence to her duties within the institution’s hierarchy.
