He never really crucial to the story anyway, his only purpose is to be the last boss of Ch 3, a very tough one at that. They just mention him as the Sphere Keeper and after said Sphere is broken, his role is no longer relevant. And 10 years have passed already in the storyline. So, we can see Emperor again.
