Latest Vocaloid Release [December 2025]

Birthdayshiroki

Birthdays / Hatsune Miku, Kasane Teto – Birthdays

This is a song that gives a push to people who feel like they’re “boring nobodies.” Created by hiroki., it’s set for release in December 2025.

It’s a duet by Hatsune Miku and Kasane Teto SV, singing a message that says “It’s okay to be yourself just as you are.” The contrast between the cool electronic sound and the expansive melodic lines is striking.

The journey of the heart from self-denial to self-acceptance is depicted within the dazzling soundscape.

Give it a listen when you need a boost of confidence.

Why did this happen?!monet

How did it end up like this?! / monet feat. Chifuyu Hanakuma

This song wraps the sensation of drowning in unrequited love in a band-driven sound.

It’s a track by the Vocaloid producer monet, released in December 2025.

It likens the swelling emotions within oneself to a “monster,” depicting how the other person’s kindness turns into inescapable chains.

The psychological portrayal—where self-denial and yearning amplify each other—feels strikingly raw.

Despite its dim, somber worldview, it’s catchy and the kind of piece you’ll want to play on repeat.

diagramabaraya

Diagram / Hatsune Miku

“Diagram” is a work by Abaraya-san, released in December 2025.

Its lyrics are uniquely sprinkled with physics and math terms as metaphors, expanding a worldview that visualizes human connections like a schematic.

The sound arrangement, with an essence of electronica, meshes perfectly with the word choices.

It’s a track to sit with when you want to think deeply about the meaning of life.

Interruption to my walkiyowa

Everything / Iyowa feat. Kasukabe Tsumugi (Getting in the Way of My Walk)

A heartwarming pop song themed around the modest everyday act of taking a walk.

Released by Iyowa in November 2025, the track is notable for the gentle singing voice of the synthetic voice library Kasukabe Tsumugi.

The lighthearted way it brushes off the clutter of world affairs and horoscopes as “distractions” lifts the weight from those of us living in an age of information overload.

Give it a listen when you’re feeling the need to reset amid your busy days.

LOVELY MIKU’S DINERkēenu P

LOVELY MIKU’S DINER / Hatsune Miku

This is a song where Miku, who works at a diner, sings out her feelings of love.

It’s a work by Vocaloid producer K-NuP, first unveiled anonymously at the event “Musyoku Tōmei-sai 3” in November 2025, with an MV version released in December.

The combination of a sophisticated sound that incorporates jazz and fusion elements with a catchy melody is just perfect! It also pairs brilliantly with the heart-fluttering lyrical world.

If you’re looking for a Vocaloid track to lift your spirits, don’t miss this one!

Qiu & Kagepiinata

Peanut - Q&A (Q&A) Kasane Teto

Conflicting concepts—math problems and life’s questions, faith and dependence, frenzy and nihilism—come rushing in atop a high-speed beat.

It’s a track featuring Kasane Teto by Piinata, released in December 2025.

The tightly punched kick and snare, together with a distorted synth bass, create a sound that’s aggressive yet somehow pop-leaning and easy on the ears.

The lyrics juxtapose the sensation of chest pain without any specific diagnosis with words that label oneself as “junk,” despite having emotions.

If you’re carrying a haze that defies rational explanation, this song might hit home.

TomedonaiOzon

Ozone – Unstoppable feat. Kasane Teto

A rock number that detonates the feeling of a brain-crash impulse and an unstoppable thought loop.

Created by Vocaloid producer Ozone and featuring Kasane Teto, this track was released in October 2025 as part of the album “In:Side.” The arrangement is addictive, blending EDM-style build-ups with the rawness of a live band sound.

And the lyric’s question—“What lies beyond these meaningless days?”—overlaps with Teto’s uniquely husky, resolute voice, piercing the listener’s heart.

When you’re carrying feelings with nowhere to go, give it a listen.
