A famous song sung by KAFU. Recommended popular CeVIO tracks (11–20)
Secret UFONayutan Seijin
I think a lot of people can tell whose song it is just from the intro.
It’s a track by NayutalieN, the Vocaloid producer from outer space, released in 2021.
This catchy mixture-rock sound is quintessentially NayutalieN.
It’s easy to get into, easy to listen to, and never gets old—at this point, it’s comforting.
The lyrics, packed tightly with the feeling of being in love, also deliver that “this is it, exactly what we wanted!” vibe.
It would definitely hype up a karaoke session, too.
Kokoro Girltoa
Even though your heart is your own, it just won’t listen, will it… This piece is by Toa, a Vocaloid producer known for hits like “Tsugihagi Staccato,” and it was released in 2021.
It’s a gentle four-on-the-floor track where a catchy melody line intertwines with the sound of piano.
The lyrics, however, are especially relatable when you’re feeling down or pondering your own reason for being.
Rather than a straightforward cheer-up song, it feels like something that speaks on your behalf and stays by your side—an accompanying presence in musical form.
Humanenessnoi
It’s a CeVIO song that makes you feel as if KAF is singing her heart out, one that really stirs the emotions.
Composed by Noi, also known for works like “Lonely Gray” and “Parastraia,” it was released in 2021.
The arrangement blends sharpness with grandeur—truly excellent.
The transition from the measured, tension-building B-melody to the liberating chorus is exhilarating.
With lyrics that compellingly depict the pursuit of hope, it’s a rock number that lights a fire in your heart.
whinysurii
There are times when you just can’t be honest with the person you like, right? This is a cute, retro pop song that sings about that kind of crush.
It’s a track by the Vocaloid producer Surii, also known as the creator of “Telecaster B-Boy,” released in 2021.
The lyrics vividly capture the love lives of young people living today, which is a big part of its appeal.
The laid-back sound matches the world of the song and has a calming effect as you listen.
It’s a CeVIO number I’d also recommend for karaoke.
HeineSaburou
The rhythmic piano phrases and groovy bassline are awesome! It’s a track by Vocaloid producer Saburou, released in 2021.
The song unfolds in a matter-of-fact way, yet I feel its soundscape conveys a kind of inner restlessness.
I imagine many people can relate to the lyrics about loneliness.
It might hit the hardest when you listen at night, alone.
And with this cool vibe, it also works great as background music for getting work done.
TransformationNanahoshi Orchestra
“Let’s push forward just as we wish”—this is an emotional mixture hard rock that puts you in that mood.
It’s a track by Nanahoshi Orchestra, a Vocaloid producer also active under the name Riku Iwami, released in 2021.
The relentlessly aggressive tone throughout is insanely cool! I can’t help but crank up the volume.
The sing-along phrases are another factor that gets the energy up! If you’re looking for fiery rock sung by Kafu, this is a must-listen.
A masterpiece sung by Kafu. Recommended popular CeVIO songs (21–30)
KafūeinHiiragi Magunetaito
A poppy, addictive track that humorously portrays a love for caffeine and everyday life.
The song by Hiiragi Magnetite was released in February 2024.
The lively rhythm combined with KAFU’s voice creates an energizing sound.
The lyrics, themed around caffeine dependence, brilliantly capture modern life.
Entered in VOCALOID Collection Winter 2024, this work made it into the CeVIO Hall of Fame.
It’s a must-listen not only for coffee lovers, but for anyone who cherishes the small joys of daily life.
