What is "kirite"

, officially typeset kiЯitɘ (see album art), is a 2005 album composed by Yasunori Mitsuda based on The Five Seasons of Kirite, a story by Masato Kato. Unlike their other previous major collaborations like Chrono Trigger, Xenogears and Chrono Cross, Kirite was never developed and published as a video game, but published as musical album bundled with Masato Kato's story text in Japanese and a collection of artistic nature photographs. The music of Kirite incorporates Celtic music, jazz and ambient noise influences.
