Yuecheng

Yuecheng (悦成), also known in English as King, is an upcoming VOCALOID to be developed by Shanghai Wangcheng in collaboration with NetEase Comics for the VOCALOID4 engine.

His voice provider has yet to be revealed.

2015
Yuecheng was a character from the manhua, "Mànhuà Jiā Yǔ Dà Míngxīng: Yuèróng Yǔ Yuèchéng" ("漫画家与大明星：悦蓉与悦成" / "The Manhua Artist and The Idol: Yuerong and Yuecheng"), which was published by NetEase Comics. Since then, he was promoted as a virtual idol. He received his own song, "心锁" ("Xīn Suǒ" / "Love Lock") in September 2015, produced by CleverCool, Zhixiaoai, and Huduoduo. At the time, the vocalist was credited as Yuecheng but utilized a live singer. This was the song that was presented in the manhua itself and allowed him to pursue his dream of becoming an idol.

2016
Some time in 2016, Shanghai Wangcheng decided to create VOCALOID voicebanks and did so using the Business-to-Business (B2B) method.

2017
As a result of Shanghai Wangcheng’s efforts to make VOCALOID voicebanks through B2B, they collaborated with NetEase Comics to give Yuecheng a VOCALOID voicebank. His production for VOCALOID4 had been known to the public since at least March 2017.

An audition to become Yuecheng’s voice provider was launched from March 14 to March 24 along with instructions on how to participate. The voting session began on March 24 and ended on April 3.

On April 11, the results of his audition was made known. In first place with 8,000 votes was 217-Jinli (217-锦鲤; 217-Jǐnlǐ). In second place with 6,977 votes was Feilünuochen (飞吕诺辰; Fēilǚnuòchén). In third place with 6,718 votes was Kemuqing (柯暮卿; Kēmùqīng). However, other finalists also received bonuses and were invited for the opportunity to participate in selecting the winning voice provider.

Yuecheng, Zhang Chuchu, and Xin Hua were to appear in an upcoming event. This was later confirmed to be the "Girl’s Beautiful Day" event hosted at Club MYST on May 13. In addition, Yuecheng’s VOCALOID character design was revealed.

A trailer promoting Yuecheng’s upcoming debut was shown on May 9 and a short instrumental clip was shown and was produced by Dr. Yun. The instrumental was later used at the event on May 13 where Yuecheng was shown dancing live onstage.

On June 8, it was confirmed that Yuecheng’s samples for "Molihua" were recorded. In addition, two more potential voice providers, Fengjingxiao (風景暁; Fēngjǐngxiǎo) and KingLeoWong, were revealed.

Yuecheng, Chuchu, and Xin Hua made appearances at the 2017 FUN event in Chengdu. He was seen performing with four dancers on stage.

On July 25, the "Molihua" test samples were uploaded and shown to the public.

Concept
Yuecheng was a character from the manhua "Mànhuà Jiā Yǔ Dà Míngxīng: Yuèróng Yǔ Yuèchéng" ("漫画家与大明星：悦蓉与悦成" / "The Manhua Arist and The Idol: Yuerong and Yuecheng"). According to his biography image, his official birthday is listed as July 28 and his astrological sign is a Leo. He has type B blood and his favorite color is red.

In his manhua, Yuecheng was an unemployed boy who stayed at home with his older twin sister, Yuerong. After she blamed him for his freeloader habits, he promised her that he would find a tenant. He aspired to become an idol with a love for dancing and singing (though he is not good at rock genres). While he was singing his song, "Love Lock" ("心锁" / "Xīn Suǒ"), a talent agent named William discovered him and wanted Yuecheng to make a contract. Yuecheng’s career as an idol began from there. He has a mature personality and it was noted that he prefers to eat sweets and dislikes spicy food.

After his debut on May 13, 2017, his biography was altered. It was noted that he has a different personality when he is performing onstage: he has a vivid image compared to his quiet nature in his normal life. His special talents include dancing, singing, performing, cooking, and drawing cards (with a lucky tendency to draw good cards). He likes playing video games (despite the fact that he’s not good at them), drawing (usually games), performing onstage, and manga. He has no pets but is a cat magnet and his character color is gradient pink.

Etymology
Yuè (悦) means "content" or "pleased" while Chéng (成) means "to finish" or "to succeed". On his official accounts and biography, his official English name is "King".

Appearance
Yuecheng’s VOCALOID outfit is different in comparison to his manhua counterpart. His color scheme consists of blacks, whites, reds, and pinks, with red being less prominent compared to his manhua version. In the VOCALOID design, he wears a black jacket with pink strings labelled “wangcheng YUECHENG” and small horns located on the hood. On the back of the jacket is a pink logo featuring a devil and his initials. He has a white sleeveless cropped shirt with a high collar and a zipper with a tag bearing his initials, long white pants with rips located on his kneecaps and parts of his thighs, as well as a black belt with his initials on it. His white shoes remains the same as his manhua counterpart in addition to his short white hair which gradates to red. On his left hand, he is wearing three rings: two located on his index finger and one on his ring finger. On his right hand, he wears one ring on his index finger.
