It’s a high-sense four-on-the-floor tune that draws you in with jazzy piano tones.
Created by the Vocaloid producer Nuyuri—known for hits like “Inochi Bakkari” and “Fragile”—it was released in 2021.
You can’t help but ponder the story between “me” and “you”; it’s the kind of song that makes you want to dive into theories or even map it out in a relationship chart.
A track with this mysterious vibe fitting into Nigo’s catalog… it just feels incredibly right.

It’s a piece with a horn section timbre that lingers in your ears, reminiscent of a musical number.
The song is by the Vocaloid producer Neru, known for numerous hits like “Lost One’s Weeping,” and it was released in 2020.
It was provided for the unit Wonderlands×Showtime.
One of its charms is the gap between the glamorous, catchy sound and lyrics themed around “sloppiness.” It makes you want to sway your shoulders leisurely as you listen.
Danceable tracks really shine in Project Sekai!

Hatsune Miku.
It was added as a unit song for Wonderlands×Showtime, and a Vocaloid-version music video was released the following month.
The song centers on the self draped in performance and roles, featuring a compelling, dynamically shifting melody line.
Its sound has depth, as if theatrical light pierces through a dark atmosphere.
When you want to take a fresh look at yourself, be sure to give this song a listen.
bugkairiki bea
A highly addictive mixture rock sound that keeps surging in! It’s a track by Vocaloid producer Kairiki Bear, released in 2022, written specifically for the unit 25-ji, Nightcord de.
The bouncing melody line makes you want to sing along before you know it.
In fact, I bet many people choose it often at karaoke.
The bold, flashy tones all the way down to the low end are quintessential Kairiki Bear! The lyrics are packed with words that feel great on the tongue, which is another draw.
It makes you want to crank up the volume!

It’s a chic, mature dance number.
“Cinema,” by Ayase—also known as the composer for YOASOBI—was released in 2021.
It’s an original song written for the unit Vivid BAD SQUAD.
The lyrics compare a life that isn’t going well to a movie, which should especially resonate with younger listeners.
The way the track moves along rhythmically feels like ideas bubbling up one after another.
The Hatsune Miku version has a more chiptune-like finish than the Vivid BAD SQUAD version.
Comparing different versions of songs in Proseka is part of the fun, isn’t it!
Stellajin
This is an original piece written for the unit Leo/need.
The song is by Jin, also known as “Nature Enemy P,” and was released in 2020.
It’s a refreshing rock number that pairs a driving band sound with the sparkling tones of piano.
After the end of the first verse, it modulates into the pre-chorus, then opens up into a liberating chorus! The strong resolve embedded in the lyrics—“We’re moving toward our dreams”—comes through in the arrangement as well.
Give it a listen when you want a boost of positivity!
