Do we think Garp is done for?

Is Koby breaking the cycle of Garp training future enemies?

I started the manga but quickly dropped it. I think the premise just didn't catch me.

Chainsawman and JJK both bring a setting that's wide enough to allow for some really interesting exploring of their concept, but for me Hell's is almost too specific.

Our location is locked in and the story pretty much rides on how interesting they can make it.

Our main characters have such a specific mission and motivation that the whole thing feels like it's on rails.
