The world of Pokemon is no fairy tale. Great clans control the supply of rare Pokemon and treat commoners like dirt, while the laws of the League fail to reach its darkest corners.
He is a Trainer from the lowest rung of society, with no connections or resources. All he has is a ruthless resolve, and not a shred of saintly compassion.
He does not oppose the League, and he upholds order in the world. He does not bully commoners, and he protects the weak.
Any clan that treats the lives of commoners like ants is fair game: Pokemon bite, moves blast them to pieces, and he leaves no survivors!
With the Pokemon at his side as blades, and the hunting of evil clans as his creed, he gathers like-minded allies and creates a Pokemon Hunters' Guild all his own, making a fearsome name for himself through sheer force and strength!
From then on, the name Black Hunter resounds far and wide. Evil clans tremble at its mention, and he stands supreme as the Black Hunter Emperor, at the very peak of the hunting world!
I hope that the author can arrange for the protagonist to subdue the sword-wielding soldiers, the bear baby, the charcoal servant, and a few more quasi-gods in the future. Dragon King Scorpion and Ice Treading Doll are also good
