Samurai Derby

Derby Musou (ダービー無双) is one of the many Samurai Warriors 4 collaboration projects with the Japanese Racing Association (JRA). One part of the project is a free-to-play online browser game. Its gimmick pairs Samurai Warriors characters with famous Japanese racehorses as they race on the Tokyo Race Course against their rivals. Music and voice actors from the game are reused for each character's story.

The collaboration commemorates and raises awareness to the 81st Nihon Debry (G1 race) on June 1, 2014. Visitors uninterested in the webgame may want to enjoy the fully voiced cinematics on the website that lightly parody the fourth title's seriousness.
