UTAU wiki

Ui Mochion (望音憂; もちおんうい) is a voicebank for the UTAU program.


On September 2011, Lotus Leaf released an UTAU named Ui. At the time, Ui didn't have a family name and her name is pronounced by the alphabet (UI or Yu-Ai). Soon when her ACT 2 released, Lotus Leaf announced her family name, Mochion, and one year later, Ui joined RimoConLoid (an Indonesian-based UTAU community). Ui and her childhood friend, Yoh were both released back in 2011, but due to the creator's personal problem they remain inactive. Lotus Leaf also released two append voicebanks, POWER and DARK. In 2017, Ui cameback with a cover of a song named Patchwork Staccato and Meteor for Kingdom Hearts PVs. Her first VCV debut song was Aishite Aishite Aishite but apparently the video was taken down by her creator.

Ui cameback with a NATIVE voicebank, the voicebank released on July 27, 2020.


Ui was born with an imperfect condition, where her left eye cannot see. Although often made fun of by others, Ui is still loving and caring. It was in such difficult times that, Yoh Seine, came and saved her. He becomes her childhood friend and Ui fell for him eventually. She became very protective of Yoh and did not hesitate to act when someone hurt him. She is also struggling to win his heart. However Ui also has doubts about trusting someone, making her unable to maintain a relationship. To overcome her distrust, Ui often flees to drugs. Seen in how she dresses, she also seems to follow the Menhera sub-culture as an outlet.
