Toripiyo’s track “sonia’s record” was released as part of the VOCAParty! event held in December 2024.

It expresses the frustration of feelings that can’t be conveyed through Miku’s singing voice, yet the continued prayers still squeeze your heart tight.

It’s also connected to past works “Anemone Glitch” and “Calmia Dolls,” so be sure to listen to them together!

graduation ceremonyfuyuyu xx

Fuyu×× debuted as a Vocaloid producer in March 2022.

Their first work is “Sotsugyou” (Graduation), which uses the Vocaloid KAFU.

It’s a story-driven song that portrays meeting a senior, the deepening of their bond, and their parting at the graduation ceremony.

It’s perfect for sending off seniors with a chorus, too.

The tempo is mid-tempo, so it won’t feel too somber—you can give a bright send-off.

For those who want to sing it, note that it stays in a high register throughout; if that’s difficult, consider arranging it.

To the Android I spent my life withmofu@

This is a song that portrays a cute yet heartrending love between an android and a girl.

The girl, being a genius, ends up being pursued by bad adults, and as she feels her life gradually wearing away, she falls in love with the android.

You might cry when you sing it.

This is a song inspired by aquamarine, the birthstone of March.

Aquamarine is a pale sky-blue gemstone that shines as if blessed by Iris, the goddess of the rainbow.

It’s mysterious to think you can hold the color of the sky in your hand.

In the same way, this song lets you carry that sky-blue hue with you in sound.

This work is striking for its vocals swaying over a near-futuristic electric sound.

It’s a track by the Vocaloid producer Miriko, also known as the creator of “Don’t Kill Mary Sue,” released in 2017.

Teto’s fragile singing voice matches the steady, understated melody line, making your chest tighten.

Listening to it feels like your whole body is being wrapped in sound.

The sorrowful message in the lyrics, directed at someone dearly important, also hits home—an outstanding Teto song.

Rain Unaware of the Sky – Low-Income P / GUMI, Hatsune Miku

You’ll be drawn in by the transparent, shimmering choral work in this piece.

It’s a song by Low-Income P, a character (model) from the manga “Wasteful Days of High School Girls,” released in 2021.

Though the rhythm and melody are understated, they somehow feel richly emotional—perhaps thanks to the lyrics.

The recurring piano timbre seems to seep deep into the heart.

If you’re performing it as a duet, be sure to practice thoroughly to avoid dissonance; otherwise, the song’s clarity and beauty may not come through.

GraduationNaisho no piasu

Created by Secret Piasu, this work was released in February 2024.

It expresses the complex emotions that accompany life’s turning points, with lyric lines that feel as if they touch on truth and pierce the heart.

The dynamic, evolving sound approach and the powerful vocals of Kasane Teto SV—and their harmony—are also captivating.

It’s perfect not only for students about to graduate, but for anyone standing at a milestone in life.

Take your time and really listen.
