Virtual singer KAF will digitally pre-release “Voiceless password 周波数0の合言葉” on 25 February at 00:00 (local store time). The track serves as a preview single from her upcoming fifth album, “Transcendent Love 深愛,” which is scheduled for release on 27 May.
Classified as a Japanese pop single, the song marks the beginning of a broader cross-media initiative that brings together music, literature, and live performance into a unified creative project.
“Voiceless password 周波数0の合言葉” explores the themes of “feelings that should never reach” and “hearts that still attempt to connect.” Within the larger narrative framework of “Transcendent Love 深愛,” the song functions as a gateway into the album’s conceptual world.
It establishes the emotional atmosphere of the project while introducing story elements that will continue to unfold across multiple formats.
The accompanying music video visually deepens the connection to both the album and its companion novel, positioning the song as a symbolic “password” within the narrative and drawing listeners further into the cinematic and layered storytelling that defines the project.

KAF’s fifth album, “Transcendent Love 深愛,” is conceived as an immersive narrative experience rather than a simple collection of songs. The album is directly linked to her solo live performance, 「Inner Echoes / Transcendent Love」, which will be held on 1 March at Pia Arena MM in Yokohama.
In parallel with the release plans, a dedicated special website has launched, featuring newly illustrated visuals by PALOW, along with a personal message from KAF. The album will include 15 tracks that span contemporary J-pop styles and emotionally driven ballads, all reflecting the inner world of the story’s protagonist.
Structured from prologue to epilogue, the album unfolds as a cohesive narrative that expresses sentiments about the future in a way that is uniquely characteristic of KAF’s artistic identity.
Through “Voiceless password 周波数0の合言葉,” KAF signals the start of a new creative phase in which music, literature, and live performance converge into a single storytelling universe.
This integrated approach continues to expand her artistic presence both within Japan and internationally, reinforcing her position as one of the leading figures in the virtual music space.
KAF is the first virtual singer from KAMITSUBAKI STUDIO and made her debut in 2018 at the age of 14. She quickly established herself as a new-generation virtual artist, recognized for her distinctive voice and unique creative world.
Her YouTube channel has surpassed one million subscribers and accumulated over 300 million total views, supported by a passionate and growing fanbase in Japan and abroad. In January 2024, she held her fourth solo concert, “KAIKA,” at Yoyogi National Gymnasium.
Following her earlier performance at Nippon Budokan, this event set another milestone as the largest-ever solo arena concert by a virtual singer. In 2026, she is scheduled to further expand her overseas live activities, continuing her journey into new and uncharted musical landscapes.
