Belinda Percy serves as an active member of the Hakuoh Academy Yacht Club, skillfully contributing to the navigation and management of the Odette II while collaborating closely with her peers. She maintains a tight-knit camaraderie with Asta Alhanko and Izumi Yunomoto, allies who later joined her in an unexpected venture. When illness incapacitated the Bentenmaru’s crew, Belinda temporarily stepped into their ranks, assuming tactical control of the ship’s weaponry alongside Izumi and April Lambert. Her role during the covert infiltration of the Princess Apricot cruise ship required her to adopt a strategic disguise: an intricately designed angel-themed ensemble that masked her identity while advancing the mission’s objectives.
