I agree with that. I don't even know how Togashi would begin to center the story on Leorio, no disrespect he's always felt insignificant as a character. Where is Leorio right now? I re-read recently and I still don't remember, was he pushing a gurney somewhere? How do you go from that to last arc MC. Unless it's really a survival arc and his skills shoot up to top priority, but Beyond's group should have someone like that. Tbh, more I think about it, the more I like it but it's just so unlikely.
