Welcome to the digital worldCrispy sara-udon (crispy fried noodle dish)
A song that could be called an invitation to the digital world.
Released in July 2025, it was created as an entry for VocaDuo 2025 under the name Team Cyber City Development Department.
Starting with a poppy introduction that invites you to a paradise where anything is possible, it suddenly shifts to portray the protagonist’s growing peril as they gradually lose their sense of self.
The ending, where they snap back to reality, features lines that feel highly relatable for those of us living in a digital society.
It’s a highly addictive Vocaloid track that will stick in your head after just one listen!
Concave ApocalypseHiiragi Magnetite
A song that brilliantly captures the conflict between longing for an irretrievable past and the determination to look ahead, expressed through a dynamic duet of two vocalists.
Released in 2021 and crafted by Hiiragi Magnetite, it fuses weighty electro sounds with a heart-wrenching melody, drawing you into a wistful yet majestic soundscape.
The lyrics, as if your own light and shadow are in dialogue, are another hallmark.
Why not sing it emotionally with your best friend, laying bare your inner selves to each other?
Annoying Pest IIDECO*27
This Vocaloid song charmingly expresses the feeling of being in love with a pop, catchy melody.
Released in 2021, it’s included on the album “MANNEQUIN.” It portrays the emotions of wanting to say “I like you,” yet being too shy and anxious to be honest—something anyone struggling with adolescent love can relate to.
It also seems fun to use when sending a message to a friend or partner while watching their reaction.
Plus, it’s a great pick for karaoke with close friends!
OverrideYase Yoshida
Since its release in November 2023, Override has become a newly etched hit in Vocaloid history, thanks to its catchy melody, breakneck-speed dance music, and lyrics that, while packed with references, still evoke a sense of inner darkness.
The producer, Yose Yoshida, originally worked at a company as a programmer, and reconsidering the title and lyrics in light of that background may reveal a variety of meanings.
If you’re going to sing it at karaoke, keeping up with the speed is the first prerequisite, but you might be surprised how far sheer momentum can carry you—and the melody itself is extremely catchy—so definitely give it a try.

Perfect for those who want to immerse themselves in music with a grand, expansive worldview, or are looking for a piece to sing passionately with friends.
Its dramatic sonic landscape will draw you in before you know it.
TagHaruno
This is a track Haruno released as a Vocaloid producer for the first time in about seven years.
Released in June 2025, the song deepens a downbeat yet beautiful worldview with a touch of fantasy.
Interweaving Luo Tianyi’s resonant vocals with oriental sounds, it creates a uniquely weightless atmosphere.
The lyrics, themed around a game of tag in the dark, depict a heart being overtaken by an irresistible pull, as if you’re reading a mysterious story.
