Rising Sun Rock Festival
Two previously unreleased songs were featured on the album. "It Was You" was a ballad written by Burt Bacharach. It was first performed at the Rising Sun Rock Festival in Otaru, Hokkaido on August 16, 2008, but otherwise was unreleased. Sheena performed the song together with the Neko Saito Quartet, and they are credited as the collaborating artist on "Ukina". "Netsuai Hakkakuchū" was a song Sheena wrote especially for "Ukina", which she asked electronic musician Yasutaka Nakata to arrange for her.
