Biography

Eternity, also styled IITERNITI, is Pulse9’s girl-group project built around realistic digital characters. The company timeline dates its preliminary AI Heartbeat Challenge to December 2020; the first single I’m Real was released on March 22, 2021. Eleven characters were planned overall, but this first song involved Yeoreum, SeoA, Minji, Hyejin and Sujin, rather than launching every member’s music simultaneously. [3] [4]

The second single, No Filter, appeared on August 27, 2021 as a Dain solo release. Its production notes identify collaboration between NUVO and the AI composition system Aimy Moon, while separately crediting a human vocalist, instruments, recording and choreography. This documents AI-assisted composition and virtual-face production, not an entirely unattended AI vocal performance. [5]

Two 2022 releases continued the unit approach. Paradise, released April 29, features Jane, Yejin and Sarang with electronic and funk elements. DTDTGMGN, released October 25, is a dance track by Jiwoo and Chorong. Its release notes identify them as the final music-debut unit, completing the introduction of eleven characters through different songs. [6] [7]

The project also moved into real-time programming. Pulse9 records Jane and Sujin appearing together on Arirang’s Super K-pop from an XR studio. Its DeepReal Live – Face description specifies applying pretrained virtual faces to human performers and streaming the result. Realistic face generation and human performance are therefore distinct production stages; this technology description does not establish fully autonomous conversation. [2] [8]

Wen Moon, released on October 16, 2023, was the first song and music video involving all eleven characters. Pulse9’s release retrospective credits THE MUZE with writing, composition and arrangement, and describes XR-studio filming with generative-AI virtual backgrounds. The full group had previously appeared in IITERNITI BEGINS : The First Journey, preceding this transition from rotating units to a complete-group recording. [9] [10]

An English version of Wen Moon followed on December 30, 2024. The first full album Hello World, dated November 11, 2025, contains eleven tracks including Kryptonite, Glitch, Luv Or Dare and the earlier Paradise and DTDTGMGN. The catalogue connects the initial singles to a full album. [10] [11]

Some historical Pulse9 pages returned 403; their indexed text was read and key dates checked against Bugs/Genie releases. The older company timeline calls the No Filter character Dain; that public name is retained without using differing credits to infer a private identity. Unit releases and specific production stages are documented, but all eleven characters’ revisions, voice sources and later staffing have not been fully audited. Event announcements are not treated as completed performances.
