Rinka (Phantom Siita)

Rinka officially debuted as a member of the Japanese group Phantom Siita on June 26, 2024, with the release of their first digital single, "Otomodachi." The group, produced by Ado, is known for its distinctive retro horror concept, inspired by the Japanese Shōwa era, which blends nostalgia with a subtle sense of dread.

After their debut, the group released their first album, Girlhood Memories, on October 30, 2024, and began their first world tour from January to February 2025.

Rinka was born on May 9, 2007. She was one of five members selected to join the idol group Phantom Siita after participating in an audition for girl groups organized by popular Japanese singer Ado. The audition process was highly competitive, starting with over four thousand applicants. Before her debut, Rinka was known for having studied jazz since school, which contributed to her unique vocal style.

As for her voice, Rinka is known for her deep voice and a singing style described as powerful and "coppery." She also has a voice that is sometimes characterized as breathy. During a conversation about her song "Devilish Girl," Rinka explained that she tried to create an atmosphere of a confident, devilish girl, as if she were "surrounded by the beautiful scent of perfume," for her role.

Rinka defines herself as the most relaxed or carefree member of Phantom Siitalo, which suggests that she doesn't take everything too seriously all the time and tends to remain calm even in intense situations.

She is not particularly talkative or extroverted offstage; in videos or short interactions she usually appears calm, somewhat reserved, as if she observes first and speaks later.

But when something truly excites or interests her, her expression changes: she becomes incredibly enthusiastic. This sudden shift—from calm to lively—makes her seem endearing and unique to many fans.

She enjoys baking sweets (although she hasn't always had time for it), and she gets excited easily but can also quickly lose interest when something stops captivating her.

Rinka is a young Japanese woman with delicate features and soft facial expressions.
