Roshi is one of the dogs who helped John, Hiro and Reika escape. After Hiro had left with Reika to look for Weed's group; Roshi, Lefty and Tomi were left with John to fight against Matsu's group. Despite the overpowering numbers, they fought bravely with John, as their fathers where Ohu soldiers in the battle against Akakabuto. However, this failed as Matsu's pack outnumbered them and Roshi was killed shortly by Matsu's minions.
