ファントムシータ (Phantom Siita)

Phantom Siita is an emerging Japanese idol group formed in 2024 and produced by the popular artist Ado. The group consists of five talented members: Mona, Miu, Rinka, Hisui, and Moka. They made their debut on June 26, 2024, with the release of their first digital single, Otomodachi.

The concept behind Phantom Siita is a unique blend of “retro horror,” which creates a nostalgic yet eerie idol image that stands apart from the typical idol groups. The name “Phantom Siita” combines “Phantom,” evoking ghosts and illusions, with “Siita,” inspired by the scientific names of butterflies and moths. This represents the group’s distinct, rebellious identity in the idol industry.

Since their debut, Phantom Siita has released several well-received digital singles, including Just Wanna XXXX with You, Mahou Shoujo, and Hanabami. Their first full album, Girlhood Memories, dropped on October 30, 2024, marking a major milestone in their career.

The group’s rise to fame continued with their first world tour in November 2024, performing in 15 cities globally. By April 2025, they signed with Universal Music Japan’s Virgin Music label, further solidifying their place in the music scene.

Phantom Siita’s music combines the energetic, upbeat elements of J-pop with dark, sinister melodies, creating a fresh twist on the idol genre. Their distinct sound and captivating performances continue to attract fans worldwide.
