Rikka Sera, a member of idol unit SolidS under TSUKINO TALENT PRODUCTION, sports light pink collar-length hair often tied in a ponytail and matching eyes, his striking beauty occasionally sparking envy. At 175 cm, his age spans 22 in 2015 to 30 in 2022, born October 16 with blood type AB. Born to a French father and Japanese mother, he modeled from infancy, growing up in the spotlight yet feeling hollow, likening himself to an emotionless doll. This emptiness nearly drove him to abandon modeling for civil service until Shiki Takamura, a childhood friend and future SolidS member, convinced him to join the group—on the condition Shiki participate as both producer and member. Encouragement from unitmates Tsubasa Okui and Dai Murase bolstered his resolve to embrace singing. Gentle and composed, Rikka nurtures SolidS with home-cooked meals and maternal care, though he sternly reprimands Shiki’s overworking tendencies. Beneath his calm exterior lies a history of self-doubt stemming from his modeling career’s perceived superficiality, gradually eased by the purpose SolidS provides. His relationships define his journey: a decades-long bond with Shiki, balancing admiration for his resilience with concern for his habits; initial envy of Tsubasa’s confidence evolving into mutual respect; morning runs and light rivalry with Dai, who aspires to surpass him. Beyond SolidS, he shares a modeling-history connection with QUELL’s Shu Izumi and mentors VAZZY’s Ouka Kira like a younger brother. An avid cook and skilled masseur, Rikka enjoys shopping and holds a driver’s license—though navigation challenges plague him, and he despises his license photo. He toys with changing his hairstyle but remains indecisive. A cosmetics commercial paired him with Dai, showcasing his androgynous charm as a princess. His fanclub "MICO," derived from the Latin "splendor," mirrors his radiant persona. Rikka’s evolution from self-criticism to confidence underscores his growth through collaboration, replacing existential emptiness with fulfillment in shared artistry. His journey weaves self-discovery with the transformative power of kinship, anchoring him firmly within SolidS’s collective identity.
