As someone who really enjoyed Naruto as a child; gotcha fam.

Hammy McBurgers is a young bounty-hunter-to-be training in the capital city of his homeland; Hidden Pine Valley. His parents died long ago while protecting their city from one of the nine fierce wild west spirits; the great and terrible Thunder Bird. This spirit was trapped and now resides within the boy, as this was the only way that total catastrophe could be averted. While not a great student all around, Hammy's connection to Thunder Bird lends itself to a certain devastating "rain of bullets" type technique that splinters his ammunition like lightning branching through the skies. This innate edge along with his hard-headed affect and unstoppable will to survive will carry him a long way through the troubles of his changing world.

There are other great spirits residing in 8 other people including the Jackalope, a cunning and world-wise spirit, the Sasquatch, an unstoppable engine of raw physical strength, the Oofoh, a strange conglomerate of small grey-green blokes with magical knowledge unrivaled, and the Chupa, a deviously wicked and constantly starving entity who keeps its host perpetually exhausted and in a state of agitated desperation.

Among Hammy's classmates, the two he gets to know best early on are Blossom, his one-sided crush who is a dedicated worker with a bit of a sweet-and-sour disposition, and Davey C, who is exactly as snobby, lame and one-dimensional as Sasuke. Him and Hammy end up holding hands at the very end and it's kind of what the whole plot revolves around in a really, very long-winded way.

A mysterious organization of elite and horrifyingly powerful outlaws known only as El Amanecer (that's supposed to be the "the dawn" but my Spanish is far from perfect, so I could be mistaken) seem to be quietly collecting and manipulating the nine great spirits, and nobody is certain why. Our young hero trains in the arts of brawling, marksmanship, and magic alike, but will his training be enough when Thunder Bird's name is next on their list?

Edit: one more of the spirits is a giant blue cow who accompanies a 7ft tall 14 yo who wields only his dining table-sized axe in battle. The boys name is Paul.
