WhiteCUL VOCALOID6 VOICEVOX | Songs Albums Notable Originals

WhiteCUL (ホワイトカル) also known as Yuki-san (雪さん) and formerly referred to as YukiCUL (雪CUL, SnowCUL), is an upcoming Japanese VOCALOID to be developed by ZAN-SHIN Co., Ltd. and distributed by Internet Co., Ltd., and is planned to be released for the VOCALOID6 engine towards the end of 2024, following a crowdfunding campaign.[4] She was formerly released for the text-to-speech software VOICEVOX in September 2022.[5]

Her voice provider has not been revealed.


In September 2020, creator and developer, HirotoP, revealed that the VOCALOID3 vocal CUL was to have siblings whom she grew up with in the Shinobi No Sato Ninja Village (忍びの里), which was under constant threat by hostile forces.[6] WhiteCUL was revealed to be the second oldest and is one of the four sisters of Fuusetsugekka (風雪月花), with each character being based on a different color (from oldest to youngest): blue, white, yellow, and red and based on the concepts of wind, snow, moon and flowers respectfully.[7]

WhiteCUL's theme color is white and is based on the concept of snow.[8] She is described as a cool beauty with an outstanding singing ability.[9]

WhiteCUL was initially 18 years old when introduced.[2] Her age was later changed to 20 on September 20, 2022.[1]


The name "CUL" has a double meaning, short for "culture" and "Culnoza", a collaborative group organized by HirotoP. Since WhiteCUL has an overall white theme in contrast to CUL's overall red theme, she is dubbed "White"CUL. The Kanji "yuki" (雪) in her nickname "Yuki-san" (雪さん), means "snow".


WhiteCUL has floor length curly white hair with frosty blue tips, thick bangs with a blue streak, and deep azure eyes. She wears many hair ornaments including two silver cylinder shaped barrettes, and a silver clip with a white flower with a blue center and ribbons. Long snowflake earrings decorate her ears. Her outfit consists of a light blue sleeveless dress, with a ruffly scalloped hem, over a blue pleated skirt. She has frost blue detached sleeves with scalloped hems, and ornate flower tassels. The bodice of her dress bears a delicate snowflake pattern. Underneath her sleeves are light blue gloves. Her fingernails are painted a chilly blue. Around her waist is deep blue obi with a snowflake pattern on it tied with a white obijime, and a sky blue bow. Her obijime is tied to the side and adorned with two cotton puffballs. The tail of her bow is decorated with an ornate silver design. A glimmering snowflake hangs from the tip of the ribbon. She wears tall heels with navy blue soles, and white toes and heels over light thigh high blue socks. A blue cord encircles her left thigh.


WhiteCUL is noted to have a timid personality and manipulates snow sorcery.[10]

On June 29, 2013, in response to MMD model creator, mqdl, HirotoP revealed that the VOCALOID, CUL, was the youngest of four sisters themed around "Fuusetsugekka". The sisters were themed around the colors of blue, white, yellow, and red respectively. BLACKCUL (Wet Crow), CUL's twin sister who was themed around the color black, was also mentioned.[17] The sisters were later featured in a comic illustrated by Megumi Inomata.[18][19]

Throughout 2020, HirotoP composed tweets in regard to CUL and the many parts of her project. He revealed that CUL's VOCALO Revolution counterpart REV was meant to become a VOCALOID, but his project fell through, and reconfirmed that CUL had conceptual sisters themed around the following colors: blue, white, yellow, and red (with CUL being the red-themed sister), as well as BLACKCUL. In response to a fan, HirotoP also expressed interest in updating CUL but did not give further details.[20]

On March 19, 2021, HirotoP revealed CUL's theme to be "red" and "flowers" while the other sisters were themed around the following: "blue" and "wind", "white" and "snow", and "moon" and "yellow".[21][22][23]


On February 17, 2022, after the introduction of ROSA, the youngest sister themed around the color pink and roses, the ages of the other sisters were revealed. "WINDCUL" (風CUL) was noted to be 19 years old, "WhiteCUL" (formerly known as "SnowCUL" (雪CUL)) was 18, "MOONCUL" (月CUL) was 17, "RE:CUL" (also known as "FlowerCUL" (花CUL) and BlackCUL were 16, and ROSA was 15.[24][11]

On March 27, HirotoP announced the RE:CUL Project, a project revolving around CUL's original sisters. The first of whom, WhiteCUL, was announced at the "Software Talk Video Posting Festival Supporting Festival" (ソフトウェアトーク動画投稿祭応援しまくる祭) from the VOICECONNECT 2 doujinshi convention to be receiving a speech library for VOICEVOX that was expected to release in the summer. Illustrations would be released in the future.[25][26][27][28] The next day, CUL's Twitter account gave a short introduction about WhiteCUL. She was introduced as the older sister of CUL at the age of 18. Her nickname was stated to be "Yuki-san" and she was the tallest of the four sisters. Her hair was noted to be tied in a ponytail. Further information was expected to be released little by little later on.[29] Recording for WhiteCUL began on April 16.[30][31] On April 23, HirotoP showed an image of him cutting the recording material.[32] By May 1, only 160 more needed to be cut before all of WhiteCUL's materials would be complete.[33]

On May 24, CUL's Twitter account announced that there would be news about WhiteCUL soon.[34] On June 3, ROSA tweeted that she and WhiteCUL would be performing at the 柚子花主催LIVE -Planet Station- STAGE.3 online concert on June 19, however, WhiteCUL's character design would not be shown.[35][36][37] On June 15, the lineup revealed that ROSA and WhiteCUL were expected to perform second, with the both of them singing.[38][39][40] On the day of the concert, without a character to represent her, WhiteCUL was instead featured as a white sphere with her name written in black font.[41] It was later clarified that the singing voices for ROSA and WhiteCUL were performed by their voice providers rather than using singing voice synthesizers. HirotoP hoped that the performances would give listeners an idea of what an AI singing voice database would sound like. It is currently unknown if WhiteCUL would be receiving a singing voicebank as, at the time, only ROSA was confirmed to be receiving a Synthesizer V AI voice database.[42]

On June 25, the progress of WhiteCUL's VOICEVOX voicebank was to be shown in a livestream at 18:30 JST.[43] On June 30, HirotoP tweeted that a rough design for WhiteCUL and a sample of her VOICEVOX voicebank may be shown soon.[44] Another livestream featuring details about WhiteCUL was launched on July 9.[45][46]

On September 9, it was announced that WhiteCUL, Goki, and No.7 would be releasing at the same time on September 30.[47] On September 30, HirotoP tweeted that a large announcement for WhiteCUL was scheduled for the next day and would be posted via the official ZAN-SHIN Co., Ltd. Twitter account.[48] This included illustrations and samples of her voice.[49][50][51] He also confirmed that her age had been changed to 20.[52]

On September 21, details about WhiteCUL's character and her illustrations, which included her key art and reference sheet, were revealed.[53][54] A sample of her "Normal" emotion for VOICEVOX was also shown.[55] On September 23, aoirooto was confirmed to be the official illustrator for WhiteCUL.[56]

WhiteCUL was released on September 30, as expected. She along with Goki and No.7 are considered the fifth generation of VOICEVOX vocals. WhiteCUL has four expressions: Normal (ノーマル), Fun (たのしい), Sad (かなしい) and Bie~n (びえーん).


On May 20, 2024, a crowdfunding campaign for the development of a VOCALOID6 voicebank for WhiteCUL was announced on her official Twitter account.[57] The crowdfund was announced to be launched by ZAN-SHIN Co., Ltd. via CAMPFIRE on May 24, and was listed as an "All or nothing" campaign with the release being unconfirmed at the time, though WhiteCUL noted that she was hopeful of getting closer to her dream of releasing a music software.[58] The official crowdfund page was made available and detailed an initial goal of ¥7,000,000 yen, with additional stratch goals added for the production of original music & PV productions and a new 3D model production for free distribution, based on WhiteCUL's new design.[59] The goal of the campaign was to develop a VOCALOID6 AI voicebank for WhiteCUL and produce goods to introduce her to the world. Funds from the crowdfund would be used should the goal be reached, for part of the VOCALOID6 voicebank development costs, production and delivery of return goods as well as various fees and processing costs and other expenses related to production.

A promotional cover was posted to the official WhiteCUL YouTube channel featuring her voice provider singing REALiZE by LiSA, providing supporters an idea of how WhiteCUL may sound.[70][71] By June 4, 41% of the goal was raised; WhiteCUL noted that she was a bit worried but remained hopeful.[72] A sample of what would be WhiteCUL's illustration designed by aoirooto was posted on June 11 in the midst of the crowdfund, as well as a full illustration of what would be used for crowdfund-exclusive merchandise and as the package illustration. A promotional commercial advertising the crowdfund was posted soon after.[73][74] By June 23, nearly 81% of the crowdfund was achieved.[75]

A commemorative YouTube broadcast was announced to be held on June 30 following the crowdfund.[76] On June 27, her crowdfund met its goal of ¥7,000,000 yen.[77] The first stretch goal was achieved on June 28.[78] The crowdfund officially concluded on June 30 with over ¥12,100,946 raised by 535 supporters.
