There is not much to find about 及川リン(Rin Oikawa) on the net right now. She sang the beautiful ballad "Blues In My Heaven" for the soundtrack of the Japanese fantasy-swordsplay-movie "Ashura-jo no Hitomi" (2005) as well as two songs for the movie "Honey and Clover" (2006), all written by the famous anime-soundtrack composer Yoko Kanno. Rin Oikawa is the main vocalist for the band Q;indivi.
