Love-Struck MutantPinocchioP

As the title suggests, this is a poignant song that tells the story of a test-subject mutant falling in love.
Created by the versatile and widely acclaimed Vocaloid producer PinocchioP, it was released in 2010.
The patchwork-like sound arrangement and jazz-influenced progression are remarkably unique.
The lyrical world, too, leaves an unconventional impression.
However, once you grasp its meaning, it becomes heartbreaking.
Please experience this tale of unrequited love with your own eyes and ears.
Love for love, by love, of lovePinocchioP

A first love, and a first heartbreak… It’s a Vocaloid song that really hits home and brings back memories of old romances.
It’s by the multi-talented PinocchioP, who also creates the illustrations and videos himself, and it was released in 2019.
The gentle resonance of the synthesizer and the bittersweet lyrics—its impact lies in that gap.
There’s a phrase, “being in love with love,” and this song is exactly that.
Only now do I finally understand the unhealthy way I used to love.
But back then, I was giving it everything I had, loving with all my might.
You shouldn’t deny all of it—accept who you were at that time.
It’s a heartbreak song that makes you feel that way.

This song deliberately emphasizes electronic elements through the combination of electronic melodies and a Vocaloid.
The Vocaloid’s voice is mixed prominently, making it easy to hear—that’s the key point.
Once we part ways, all the days of happiness crumble away.
It boldly expresses that sense of transience.
The ghost of words is watchingFrokuro

Even though different vocals are coming from the left and right, the sense of unity as a song never falters… it’s a captivating piece.
It’s a track by the Vocaloid producer Frokuro, who creates from unique and epoch-making ideas, released in 2020.
The standout charm of this song is, above all, the vocal work.
With simultaneous left-right singing that rhymes and even kicks off a word-chain game, it delves deeply into playful wordcraft.
Despite such an artistic approach, it remains musically catchy—perhaps because it spotlights the rhythms of Japanese.
Or rather, it’s a Kasane Teto song so compelling that it’s hard to express its appeal in words.
Red-and-white rotating Da FlasburnMaksiukyō

A catchy track that fuses chiptune and electropop.
Composed by Makisiukyou, it was released on October 10, 2024—“Teto Day.” Centered on the theme of pushing forward in the face of hardship, it vividly captures the protagonist’s resolve to say “I’ve just got to do it” through Kasane Teto SV’s vocals.
The dramatic song structure and melody are excellent, as is the highly narrative animated music video created by Makisiukyou himself.
It’s an energizing number that I hope anyone chasing a dream—or running up against the walls of reality—will listen to.

Life is often compared to a voyage.
This is a song that shows why those two are so often paired.
Despite its snappy melody and rhyming lyrics—elements that make you want to hum along—you somehow find yourself listening quietly.
When you set out on an uncharted voyage, you can’t tell whether the bond with the person going with you is love or friendship.
Even so, it’s a song that makes you feel you want to be with someone.
Love Is a Maple DuetYuni Neko P

The track weaves in dramatic exchanges, and the back-and-forth of the duet parts creates a pleasantly resonant harmony.
It delicately depicts the feelings of being in love, evoking a sweet, bittersweet emotion.
