During the '00s, Endou usually worked on the VS. series games (with veteran sound designer Satoshi Ise) and then later worked on titles produced by Yoshinori Ono and Ryota Niitsuma. These include Street Fighter IV and Marvel vs. Capcom 3, both of which he served as Sound Director. In late 2009, Endou left the company and opened Forcewick, his own sound design studio.
