Asura fell in love with Shiki, they are have a daughter named Mikoto. He had a long-standing conflict with Yuga, and Yuga raged in order to achieve "the unification of the world and the world of the earth."
Yuga imprisoned Asura in the Netherworld and then also escaped when he was defeated during the events of Samurai Shodown 64. When he faced Yuga, but his clone, Shadow Asura, helped him kill the demon. They put themselves together so that his clones can survive.
But later on, Asura was revealed as the shadow of the real Asura. Yuda is the result of the merger of Asura and "Shadow Asura". While he then ordered his clone is the one who retains the original memory; this Asura only retains his original ability and his hostility towards Yuga.
Asura feels nothing but hate for Yuga and wants nothing but the destruction of his nemesis.
- The fusion of both Asuras creates Yuda, a character who will be seen in the Distant Finale.
