About 巡音ルカ / Luka
Megurine Luka (巡音ルカ / Megurine Luka) was the third Japanese Vocaloid2 from Crypton and released on January 30, 2009. Yū Asakawa (浅川 悠 / Asakawa Yū) provided the voice for the "cool, somewhat mysterious" character.
Her introduction was firstly by code (CV03) and her existence was made known during the Kagamine original release promotions and was intended to be the last of the CV series vocals, on 05/01/2009 the first letter of her surname was revealed with the promise of more information to come. On the 06/01/2009, Megurine Luka was revealed. Like its previous two characters, Crypton advertised Luka's vocal database as "Japanese".
However, like with Kagamine Rin, a second voicebank was shown shortly before her release that gave her capablities to sing in English. This was revealed on the 14/11/2008. At the time of Luka's release, there was a growing interest in English speaking Vocaloids. Luka offered both languages for the price of one to Japanese Vocaloid users giving them the chance to test their skills at English capable Vocaloids.
