Pokemon: I'm Invincible as a Master!

[System] [Single Heroine] [Slightly Overpowered]

When someone who only knows Pokemon in theory arrives in the real Pokemon world, he goes from dreaming, to taking action, to making that dream come true. Years later, when someone asks how he became the world's number one, this is what he says:

“Honestly, there isn't really a reason. If I had to name one, I'd say hard work. I've always relied on my own efforts.”

The Pokemon behind him look at him as if to say, “That's right. It's all thanks to you.”

This is the story of a transmigrator's struggle in another world, and how he becomes the strongest in the world.

(This is my first time writing a book, so please tell me directly if there's anything wrong, and I'll do my best to fix it. I haven't played many games, and have mostly watched the anime, so what I write might differ from the games. I'll do my best to make it good.)

(I tend to forget things while writing, so if there's something that should have appeared but hasn't, please remind me.)
