Fourteen Vocaloid Singers, One Ending Theme

The ending theme of Stretch, titled “Houkago That Couldn’t Become a Constellation”, features a total of 14 Vocaloid voices.

It starts with two voices, then adds more characters verse by verse, culminating in a full ensemble at the final chorus. Each character’s voice is matched with a specific Vocaloid from the Voisona platform.

This wasn’t just for novelty—it reflects the growing bonds between characters throughout the story. They start isolated, but gradually find harmony. I wanted the song to capture that, quite literally.
