I don't think he will, unfortunately. They don't really explain it very well in the game but the reason he could keep coming back is because of how he grasped onto the world using others hate. At the end they set a trap where in that world Susano'o is the hero of the dark war, so no one hates him. Ragna let go of his grudge and kills Terumi so he can't bring himself back again. Though the fact he's the living will of the Susano'o unit sort of makes me question if getting rid of him forever is possible.
