The software maker Crypton Future Media has announced on Tuesday that the third virtual singer in its Character Vocal Series will be Megurine Luka. The Character Vocal Series uses voice samples and Crypton's version of YAMAHA's Vocaloid software engine to create entirely new songs when ordinary computer users type lyrics and musical notes. Crypton's official blog had announced on Monday that voice actress Yuu Asakawa provided the "moody yet husky female voice" for the "cool, somewhat mysterious" character. A "version 0.9" of her rendition of "Amazing Grace" can be heard on the official blog, as well as unmodified and tweaked versions of another demo song. The character's software will go on sale in Japan on January 30.

Unlike its previous two characters, Crypto advertised Luka's 3GB vocal database as "Japanese/English bilingual," and chose her name to express its hope that she will transcend borders and cultural barriers. The name "Megurine" can be read in Japanese as the "sound that travels (the whole wide world)," and the name Luka invokes the homonymous Japanese words of "nagare" (flowing) and "ka" (song) or "kaori" (scent). Her fictional profile is as follows:

Age 20 years old
Height 162 cm (5 feet, 4 inches)
Weight 45 kg (99 pounds)
Preferred genres Latin jazz to ethno-pop/house to electronica dance
Preferred tempos 65 to 145 BPM
Preferred singing range D3 to D5
