Classic songs sung by Kasane Teto. Recommended popular UTAU tracks

Created in 2008 as one of the April Fools’ pranks on the internet forum 2channel and later actually turned into a UTAU voicebank by volunteers, “Kasane Teto.”

This time, we’ll introduce popular and classic songs sung by Kasane Teto, who has such an unusual origin story.

The voice model was Namine Momoyo Koyama, who was a junior high school student at the time, yet her singing voice carries a somewhat mature vibe.

When it comes to UTAU, these are exactly the wonderful songs you’ll want to introduce first!

Masterpieces sung by “Kasane Teto.” Recommended popular UTAU songs (21–30)

Confession to the Sisterhaihara memorandum

I’m captivated by Kasane Teto SV’s beautiful singing voice.

Released by Haibara Memory in February 2025, this work features an impressive gothic-style electronic sound that exudes a solemn atmosphere.

The lyrics unfold a story about a sister who grants “forgiveness” in a church setting.

The worldview weaves in the “Seven Deadly Sins,” yet only six sins appear in the lyrics… It’s a Teto song that really fuels speculation about what that implies.

I love the shift from the quiet intro to the suddenly fiery beat.

The bittersweet lyrics and the way the chorus swells are striking.

It feels like a work that contains both stillness and motion, coldness and heat—an ambivalent duality.

It’s available for karaoke on JOYSOUND, so please give it a try.

No Longer HumanSakura Ryūsei

Released in October 2024, this work by Ryusei Sakura featuring Kasane Teto is a striking piece where the timbre of the piano blends beautifully with a soaring vocal performance.

The sound design is both swift and weighty.

The lyrics, inspired by Osamu Dazai’s novels, depict the emotions of a protagonist burdened by nihilism and loneliness.

You can’t help but be drawn in by the swell of emotion in the chorus.

It’s a song I especially recommend to anyone struggling with self-discovery.

This piece, with its beautiful blend of piano and strings, captivates the heart—a mix of poignancy and comfort.

It’s a track by Vocaloid producer Ashu, posted on April 1, 2024, for Kasane Teto’s birthday celebration.

The expansive, band-driven arrangement harmonizes perfectly with UTAU Teto’s vocals.

As you listen, you can almost feel your body gradually filling up with sound.

Born on April Fool’s Day, “Kasane Teto” seems to have her very reason for existing distilled into this song.

Peanut - Tetrodotoxin feat. Kasane Teto

An ambitious work by Pi-nata that draws you in with its toxic melody.

Released in July 2024, this track is a full-on showcase of Kasane Teto’s allure, centered on the theme of dissatisfaction with modern society.

Set to an electronic sound and an uptempo 140 BPM rhythm, it voices frustration with society and self-loathing.

The music video’s stylish animation is another highlight.

It’s a song for anyone feeling worn out by everyday life—there’s sure to be something you can relate to.

What’s going on? / Kasane Teto (Donut End)
What's going on?mitsu akuma

It’s a work that fuses poignancy and exhilaration, gripping listeners’ hearts and never letting go.

Composed by Mitsu Akuma, it was released on June 5, 2024.

Riding on the driving, Eurobeat-infused rhythm, Kasane Teto’s adorable vocals resound throughout.

As you listen, you get the sensation that the sound is overflowing from within your body.

The lyrics, infused with the struggles and anxieties of today’s youth, pierce the heart.

It was also used as an event song in Project SEKAI and enjoys high popularity both in and out of the game.

It’s a must-listen for anyone seeking a chance to face themselves.

TetrisHiiragi Magunetaito

Right now, the most talked-about Vocaloid track is “Tetris.” It’s a new song by Hiiragi Magnetite, characterized by a flashy sound that carries a touch of denpa-style essence.

While this piece doesn’t necessarily feature ultra-high phrases, it’s packed with high lines throughout, and the pitch leaps are extremely sharp, giving it an overwhelming level of difficulty.

With few break points, it also demands strong lung capacity—another challenging aspect.

Be sure to add it to your repertoire.
