Dorothy West is a 14-year-old idol at Paprika Private Academy. Of mixed Canadian and Japanese heritage, she is the older twin sister of Reona West, sharing a defining close relationship where she is fiercely protective of him and he helps ground her. She often mixes English into her Japanese, bursting out with her signature catchphrase "Tension Max!" when excited. Her appearance features short light blue hair styled with a single braid on the right side and hair accessories on the left, complemented by electric blue eyes. She typically wears a sailor's hat. Dorothy favors the Fortune Party fashion brand, which she shares with Reona, marking them as the first main characters to share a brand. Bright, cheerful, and energetic, Dorothy's idol personality also includes pride, immaturity, occasional bossiness, and a sharp tongue. She occasionally employs flirtatious charm. Early on, driven by shared vengeful feelings toward SoLaMi♡SMILE after Sophy left Usagi, she teams up with Usagi, showcasing initial pettiness and stubbornness. As she bonds with Laala Manaka and others, these traits fade, replaced by deep care for friends and strong reactions to perceived betrayals, as seen in Episode 13. Her bravery contrasts with Reona's immunity to fear. Key relationships include her protective bond with Reona, her evolving friendship with Laala (including their partnership in the PriPara Police unit), and her initially contentious but eventually valued dynamic with Sion Todo. Dorothy forms the central idol unit Dressing Pafé with Sion and Reona. In the film *Everyone, Assemble! Prism☆Tours*, Dorothy travels on the Prism Tour train. With Dressing Pafé, she performs "Change My World" against SoLaMi♡SMILE. Stranded in the Mascot Graveyard during a system malfunction, she receives Prism Stones from Cosmo Hojo. Alongside Laala, Mirei, Sophy, Sion, and Reona, she incorporates Prism Acts into the performance of "Realize," helping restore the collapsing Prism World, highlighting her growth as a team-oriented idol. Dorothy continues developing, eventually achieving God Idol status alongside Reona and Sion before relinquishing the title. She participates in multiple Dream Idol Grand Prix events, consistently teaming with Laala, and becomes the last member of SoLaMi♡Dressing to obtain a Super Cyalume Coord. Her personal growth is reflected in her 3rd place ranking in the Prima☆Donna? Memorial! Cup.
