Ash, with his invincible physical body, wants to become a Pokémon Master

"Why can't the trainer participate? Do you believe I can kill Arceus with one punch?!"
He was transported to the Pokémon world, but his cheat ability was to enhance himself.
Ash has no choice but to embark on a journey where he relies on Pokémon daily and takes on opponents himself when necessary.
"Articuno, you may have defeated Pikachu, but now you'll have to face me!"
I knocked out Articuno with three punches, making it kneel and sing "Conquer".
"We must fight evil Pokémon and bad trainers; only then can we be considered healthy!"
Ash Ketchum, the legendary Pokémon Master, leader of the Pokémon League, and everyone's forever loving father, said this.
Ordinary people in the Pokémon world: "Ash, Valkyrie, we respect and love your Teemo! Long live it!"
The world is based on the Pokémon anime, features multiple female protagonists, and has a system.
