Who Is FISORI?
FISORI is a Russian K-pop soloist and a member of OF’CORE under Na Entertainment. She debuted solo in 2023 and has released more than ten digital singles across English, Korean, and Tatar. She joined OF’CORE -then called NWH:I-in 2026 after the group restructured and rebranded.
Early Life and Pre-Debut Career
FISORI was born on October 6, 2007, in Moscow, Russia. Fan databases report that her father has mixed Tatar and Korean heritage, which she referenced in her 2026 Tatar-language single “Кояш”. No verified information about her primary or secondary education has been published.
Her pre-debut career began in the cover-group space. In November 2021, she became a member of the cover duo Lunar Plexus alongside Ruslana. By the end of 2022, the duo’s account had shifted to posting only FISORI’s activities, and the partnership appears to have ended.
On March 3, 2025, she was revealed as a member of the K-pop cover group Hot Generation. The group’s final social media post appeared on January 25, 2026, after which it became inactive.
Solo Music Career
FISORI’s solo debut arrived on May 5, 2023, with the digital single “Kiss Woman.” Her second single, “Born Again” (August 26, 2023), was described by Kpop Fandom as her first release “to be considered K-Pop”.
She followed with a steady stream of singles:
- “Light in Paradise” (September 12, 2023) – her first all-English release
- “피소리” (January 24, 2024) – her first Korean-language single
- “Poison Star” (February 26, 2024)
- “Black Fire” (June 1, 2024)
- “Vampire” (September 24, 2024)
- “Insomnia” (December 25, 2025)
- “Кояш” (May 30, 2026) – her first Tatar-language single
- “Red Dragon” (June 5, 2026)
- “I.W.” (July 17, 2026)
No solo chart placements or music-show wins for these releases have been publicly confirmed by Circle Chart, Hanteo, or major Korean media. The absence of verified chart data is not evidence of failure; it reflects the limited chart reporting available for independent and mid-tier agency releases.
OF’CORE: Group Career and Current Status
OF’CORE debuted on October 24, 2025, under the name NWH:I with the digital single “Like a Flame.” The original seven-member lineup included Nina, Via, Seungjoo, Alice, Nicole, Mariam, and Vanesya.
On June 30, 2026, Na Entertainment announced that the group would pause activities following discussions with the members. On September 3, 2026, the agency confirmed that NWH:I would be rebranded as OF’CORE. The rebranding followed the departures of Nina, Via, Seungjoo, Alice, Nicole, and Vanesya from the label.
The current OF’CORE lineup consists of six members: Sori, Nabi, Mariam, Han Jinhee, Rina, and Lee Yena. FISORI was revealed as a member on September 15, 2026, alongside the other new and returning members.
The group’s fandom name is NEW:S. As of October 2026, OF’CORE has not announced a new release date or promotional schedule beyond rebranding content.
Personality and MBTI
FISORI’s self-reported MBTI is ENFP-A. The designation appears in Kpop Fandom and Kpopping, both of which source idol-provided profile content. MBTI is a self-reported personality preference, not a diagnostic tool. No verified interview expands on how she applies the framework to her work or daily life.
Lifestyle Fact Check

What is documented is her professional activity as a dancer and model, which implies movement-based training, but no specific routine has been disclosed. Readers should treat social-media speculation about her lifestyle as unconfirmed.
No publicly documented tattoos, car ownership, property information, phone model, or pet information is available through reliable sources. No verified dating information exists. No plastic-surgery claims are supported by confirmed statements; appearance-based speculation is excluded from this profile.

International Reception and Critical Coverage
FISORI’s international footprint is concentrated in the global K-pop fandom and cover-dance ecosystem. Her multilingual releases- English, Korean, and Tatar- indicate an intentional outreach to multiple audiences, but no major English-language outlet has reviewed her solo work.
OF’CORE’s rebranding received coverage in Indonesian and Chinese K-pop media, including IDN Times and Chinese Wikipedia, primarily focused on the lineup changes and group name transition. No Billboard, Rolling Stone, NME, or major Korean newspaper review of FISORI or OF’CORE was located during research.
