The Silkmoth Fangire of the World of Kiva was among several Fangire who fought for their king, Wataru, against the Riders and Undead of the World of Blade when their worlds were merged into the world of the Rider War. The Fangires later help Saga defeat the Oni Riders from the World of Hibiki before he is killed by Hibiki. After it is revealed the Fangire had allied to Dai-Shocker along with the Undead as their queen abandoned Wataru to marry Apollogeist, she is destroyed alongside the remaining Fangire and Undead by Diend's Dimension Shoot.
