[Kagamine Len] soundless voice [Album Remaster · New PV]

This is a song created with a worldview in which snow, which absorbs sound, is akin to poison for VOCALOIDs, whose voices are their lifeblood.

Together with its answer song, “proof of life,” it is reportedly counted as one of the three great tragedies of Kagamine.

Created by Vocaloid producer Kyiku and released in August 2025, it presents a dim, haunting world centered on the theme of “failed eclosion,” leaving a deep impression.

As the creator says they “wrote as honestly as possible,” the lyrics lay bare a soliloquy-like wavering of emotion, and the trembling sound design draws listeners into deep introspection.

On nights when you’re sunk in a helplessness you can’t shake, when you want to immerse yourself in music alone, this work is sure to stay close to you.

A rock tune crafted by Maya, who is also active as a professional guitarist.

The low-voiced duet of Kamui Gakupo and KAITO vividly portrays the scene of rain falling on a summer night, tightening the listener’s chest.

The heavy guitars and their harmonies resonate with aching poignancy.

The lyrics, filled with helpless feelings toward days gone by and a yearning to reunite with a cherished person who is no longer here, are equally heart-wrenching.

It’s a perfect track for nights when you want to drift into contemplation.

This is a work by Fuyukan that feels as if the very atmosphere of early summer has been turned into sound.

Kagamine Len’s heartrending vocals and the Japanese-style arrangement are a perfect match.

The song portrays a bittersweet longing for a season that has passed, and the quiet, helpless feelings of thinking about someone precious who is no longer here.

The melody line that sparks the imagination is outstanding.

Why not take some time alone after the rain to fully immerse yourself in its world?
