Exactly. But he will join much, much later. And not for that long, from my perspective...But, maybe, this is goes from the fact that I value PoH and want more of him.

If you are fine with spoilers, PoH joins in the 15th volume. So, if I understood it right, he will appear in the 3rd cour of anime. [One cour is 12 episodes, they say].
