Megurine Luka (巡音ルカ) was the third Japanese Vocaloid2 from Crypton and released on January 30, 2009.
Her surname combines Meguri (巡, circulate or around) and Ne (音, sound), while the name Luka invokes the homonymous Japanese words of "nagare" (流, flow) and "ka" (歌, song) or "ka" (香, scent); thus making "songs to all around the world as scent spreads." Yū Asakawa (浅川 悠) provided the voice for the "cool, somewhat mysterious" character.
Like its previous two characters, Crypton advertised Luka's vocal database as "Japanese". However, like with Kagamine Rin and Kagamine Len, a second voicebank was shown shortly before her release that gave her capablities to sing in English. 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.
Crypton Future Media chose her name to express its hope that she will transcend borders and cultural barriers. Luka was designed by the Japanese illustrator Kei, who had previously created the designs for Hatsune Miku and Kagamine Rin and Len.
