Hideyuki Fukasawa is a Japanese composer who has frequently collaborated with Capcom and also engages in freelance work. Although he had a minor role as an assistant sound engineer and programmer to Taro Iwashiro, the renowned music composer of Onimusha 2, it was his contribution to Chaos Legion that earned him significant recognition among video game enthusiasts. In 2008, Fukasawa composed and arranged the music for Street Fighter IV, Marvel vs Capcom 3: Fate of Two Worlds, and updated versions of both games, with some tracks remixed from previous games. He also served as the lead composer for TYPE-MOON's latest visual novel, Mahoutsukai no Yoru in 2012.
