Miyuki Masara (美雪マサラ) has three voicebanks for the UTAU program.


Miyuki's original VCV bank was released on January 3, 2017. This bank is monopitch with a very small range. This version of Miyuki has since been re-released three times to fix oto issues. This bank will likely never see another update.

On November 15, 2019, an updated powerscale KIRE voicebank was released for Miyuki. The bank is tripitch and gets more powerful the higher the pitch. The voicebank is CVVC with some English extras.

On December 29, 2019, a CVVC English bank was released for Miyuki. This bank matches her previous powerscale KIRE bank in terms of tone and pitch.

On January 7, 2020, an update for Miyuki's CVVC KIRE bank was released to celebrate her 3 year anniversary and fix some of her noted issues.


Miyuki is an alien from the planet Zecersonia, which is just outside the visible solar system, roughly what would be about an eighth of a lightyear from Pluto.

Zercersonia is considered to be a hub planet as many other species congregate to rest from their long travels.

Miyuki was sent to earth through the Zecersonia space cadet program and is the first Zecersonian to make contact with humans.

While she researches human life, she is the lead singer of a band called December Arrest, which plays metal music.

Miyuki has Aspergers Syndrome, and while it allows her to be highly skilled, intelligent, and creative, it sometimes impacts social interaction and emotional communication.

Miyuki has built a robot herself, Yuina.

Miyuki has a younger sister, Mieko, and Hanae and Hayate are their parents.

Likes: Cows, pomegranates, death metal, dancing, science

Dislikes: Hurting others, not being able to relate to others, lacking empathy

  • Miyuki has three standalone breaths and vowel end breaths for each pitch.
  • Miyuki's English has extra rolled Rs.
Vocal traits as noted:
  • Miyuki's VCV is soft and has a small range. Because of the BPM she was recorded at and existing oto issues, the voicebank lags on certain notes. She becomes muffled at some points and sometimes harmonies will sound awful.
  • Miyuki's CVVC KIRE is a much improved version of the original VCV. The lowest pitch sounds deep and dark, the middle pitch is loud and versatile, and the highest pitch is powerful and sounds like shouting. Harmonizing is much less painful with this bank.
  • Miyuki's CVVC English matches her existing CVVC KIRE bank, and is recommended for singing in English. Her lowest pitch is deep and solid, the middle is clear, and the highest is shouted and the most powerful.
Software issues as noted:
  • Miyuki VCV definitely has more issues, and is being phased out in favor of Miyuki's KIRE.

Original VCV

  • Sometimes Miyuki's notes will lag and sound awful.
  • She is soft and becomes muffled, making harmonizing a struggle. It's recommended to use different g flags on her harmonies.
  • Fresamp and the flags BRE0Y99C99c99H0h0B0b0F1L1 are the best for Miyuki.


  • Miyuki's bank should be used as fully CVVC to get the best experience.

CVVC English

  • While there aren't notable issues in Miyuki's English bank, her reclist may be more difficult for those to pick up that don't have prior experience with English UTAU banks.
