Description
Dorothy West, an eighth grader at Paprika Private Academy, embodies Canadian and Japanese heritage through her father and mother respectively. She speaks in a lively mix of English and Japanese phrases. Her appearance features bright blue eyes and short light blue hair styled with a distinctive right-side braid, often topped by a sailor hat worn on the left.

She radiates a bright, cheerful personality, enthusiastically embracing a pop idol persona. This energy is balanced by prideful, immature tendencies, a bossy demeanor, and a sharp tongue. Dorothy strategically employs charm to influence others but reveals seriousness when needed. She notably self-references using the masculine pronoun "boku" and fiercely guards her younger twin brother, Reona West, their deep sibling bond anchoring her emotionally. Her energetic catchphrase is "Tension Max!". While certain abrasive traits soften as she values friendships more, she remains easily frightened and prone to disciplinary warnings, accumulating over one thousand tickets.

Dorothy's idol journey starts with a cameo seeking to join Laala Manaka and Mirei Minami's unit. Rejection follows when she demands Reona's inclusion, prompting her to form Dressing Pafé with Reona and Sion Todo under manager Usagi, united by rivalry against SoLaMi♡SMILE. Despite persistent clashes with Sion due to opposing personalities, their collaboration proves effective. Dorothy participates in key unit alliances: SoLaMi♡Dressing to awaken Falulu using the Paradise Coord; Dressing Flower with Fuwari Midorikaze; Cosmic Omurice da Vinci; FriendAll; and PriPara Police alongside Laala and Mikan Shiratama.

Key developments include Dressing Pafé's temporary disbandment, causing estrangement between Dorothy and Sion. They reconcile after witnessing Reona overexert himself, reforming the unit. Dorothy achieves milestones like being the last in SoLaMi♡Dressing to obtain her Super Cyalume Coord and attaining God Idol status alongside Dressing Pafé, later relinquished. She consistently teams with Laala across Dream Idol Grand Prix tournaments.

Her preferred idol brand is Fortune Party, shared with Reona, making them the first main characters to share a brand. Significant coords include Twin Gingham, Fortune Party D Cyalume, Dressing Pafé D Team Cyalume, Dream Fortune Party D Cyalume, Fresh Dressing Pafé D Team Cyalume, and Super Cyalume variants. Trivia notes: her name references the solfège notes "Do" and "Ti"; her birthday is February 5th (Aquarius); her favorite food is monjayaki; she ranked first in a 2017 Dream Team election; early designs contemplated white hair for her and Reona.

Her family includes father Mr. West and mother Mrs. West, from whom both twins inherit personality traits, along with younger twin brother Reona. In the idol sphere, she rivals Mirei Minami, Laala Manaka, and Sophy Hojo, yet maintains underlying respect. Her relationships feature friction yet cooperation with unitmate Sion Todo, deep mutual care with Reona, and collaborative bonds formed through teams like SoLaMi♡Dressing and PriPara Police. She interacts with other idols including Aroma Kurosu, Mikan Shiratama, Fuwari Midorikaze, and Nino Nijiiro, offering guidance to the latter.

This journey unfolds across television series, films, and related media, with Dorothy maintaining her core identity while experiencing growth in relational dynamics and idol achievements.
