HxH always follow this formula for its story arcs.
Main characters arrive at New setting
Main characters meet so new badass villians
Losses the first few rounds, shit's too much for them
Meets a Guru, train under Guru, 20+ chapters focusing on just training, lots of meaningless mumbo jumbo explaining what Nen can do, it's almost endless and torturous.
villians continue doing their things
Fully trained
Own lesser villians, has tough fight against higher rank villians, still wins anyhow
BAM! end arc
after the chimera ant chapter i kinda stopped reading. Thogugh i like how brutal the arc can be, kids getting skewered, people getting eaten, arms legs getting ripped, awesome shit.
