Description
Seto Rika leads the university DJ unit Merm4id. Embracing the motto "Life's too short not to have fun!", she enjoys a vibrant campus life centered around dancing, singing, and parties with friends. Her DJ journey started alongside best friend Marika Mizushima; Saori Hidaka and Dalia Matsuyama later joined the unit after Rika met them at a club. She tackles challenges primarily through her innate luck and energetic, charismatic personality rather than deep technical expertise.
Physically, Rika has light auburn hair, typically styled in curled pigtails with side-swept bangs. Her eyes are a brownish-gold color, and she possesses a fair complexion and a slim, fit physique. She stands 160 cm tall with blood type A.
Her personality radiates optimism and activity, creating a contrast with the more reserved Saori. Known as "The Life of the Party," her charismatic energy naturally draws others into her activities, particularly appealing to high-spirited individuals from other units. While renowned for her party spirit, Rika also demonstrates deep empathy. This is evident when, after inadvertently burdening Saori with organizing a complex international DJ collaboration, she actively supports Saori to resolve the ensuing difficulties, offering genuine concern and practical help.
Before forming Merm4id, Rika lived an ordinary university life. The unit formed organically: Rika and Marika began DJing together, later incorporating Saori—who was initially reluctant but inspired by Rika's drive—and Dalia, who sought out Rika's inherent positivity. Her name carries thematic weight: "Seto" (瀬戸) combines "Se" (瀬, rapids/waves) and "To" (戸, door/family), while "Rika" (リカ) is written in katakana. The portmanteau "Setori" (セトリ) resembles "set list," reflecting her DJ role.
Notable traits include proficiency in volleyball, a dislike of mold and spiders, and a fondness for theme parks. She owns a motorcycle and enjoys spectating sports. While her English ability is limited, she manages communication with non-Japanese speakers. Her family consists of parents and an older brother. Her favorite food is premium kalbi (grilled beef ribs).
