Megurine Luka

Megurine Luka (巡音ルカ), codenamed CV03, is a Japanese VOCALOID developed and distributed by Crypton Future Media Inc, and was initially released in January 2009 for the VOCALOID2 engine. She is the third release of Crypton's Character Vocal Series and is a Character Voice VOCALOID. In March 2015, additional voicebanks and an upgrade to the VOCALOID4 engine were released.

Her voice is provided by the Japanese voice actress and singer, Yū Asakawa, who was recorded in Japanese and English for the voicebank.

As of August 31, 2019, there will be no further installments with the VOCALOID program. Instead Crypton is focusing on their own program, Piapro Studio.

Etymology
Her surname combines "Meguri" (巡, circulate or around) and "Ne" (音, sound), while the name "Luka" invokes the homophonous pronunciations of 流 (ru, flow), 歌 (ka, song) and 香 (ka, scent), thus making: "songs to all around the world as scent spreads."

Her name is based on her concept, which is "travelling sound", meaning words which are translated from one language to another.

Her codename of "CV03" means "Character Voice 03".

Appearance
According to KEI, who was asked by Crypton to illustrate her, She is based on the "Yamaha VL1 VL-1". Her dress was designed to look old-fashioned to make her represent the past. As a form of contrast, the "∞" on her neck area represents "sound around". Her design incorporates woodwind and brass instruments. The gold curl design on her chest mimics brass instruments and a circulatory organ. The blue jewel near her throat represents moisture in the air and water drops.
