Yū Asakawa

Yū Asakawa is a Japanese female voice actress and the voice provider for the Vocaloid2 Megurine Luka. She was born in 1975 in Tokyo, Japan. The Luka project started in the early of 2007, preceding Hatsune Miku and Kagamine Rin/Len projects. Crypton had the idea of releasing Luka as their first Vocaloid2 product, but the schedules of Yu and the company did not meet one another, so Luka was distributed as the third Vocaloid of Crypton following Miku and Rin/Len.

Yu can speak competent English, which is the reason why Crypton used her voice for Luka.
