JYGA – Kagamine Rin & Kagamine Len

An electro tune that’s both heartrending and intense, woven by a duet of Kagamine Rin and Len.

Composed by Vocaloid producer Amela, it was released in August 2025.

Its oriental electronic sound leaves a strong impression.

The lyrics evoke the purity of a protagonist who has yet to know the world, and the image of them struggling desperately in a chaotic reality—shaking listeners to their core.

When you need courage to face something, listening to it will surely give you a push.

BUMP OF CHICKEN feat. HATSUNE MIKU「ray」

Released in 2014, “ray” exquisitely matches the beautifully delicate vocals of Hatsune Miku with the sound crafted by BUMP OF CHICKEN to create a unified world.

Its catchy, pop-leaning melody and lyrics that remind us of the importance of facing forward, even when everyday life is tough, are major draws of the song.

Another distinctive feature is how the vocal parts alternate between BUMP OF CHICKEN’s vocalist, Fujiwara, and Hatsune Miku’s main melody.

The way one takes the lead while the other harmonizes unveiled new possibilities for the fusion of Vocaloid and band music.
