[Transmigrating to Pokemon] + [Amnesiac Protagonist] + [Eerie Descent]
The protagonist transmigrates, without a golden finger or a powerful System. All he has is an unshakable conviction and the bonds he shares with his companions.
As the protagonist's memories return, we'll gradually learn why he lost them and uncover the conspiracy behind what happened.
Story outline: The Eerie Descent affects the entire Pokemon world, and region after region falls. In the early stages, the protagonist fights monsters and levels up in the starting village. The other regions won't be liberated until the middle of the story.
(Only the first few chapters are somewhat bleak and disturbing. If you don't want to read them, you can skip straight to chapters 7 or 8.)
The author loves Pokemon and eerie stories, so they decided to combine the two.
However, the author hasn't watched much of the Pokemon anime and hasn't played many of the games either. Most of the information came from online research.
So the author took a shortcut: the early story takes place in an original region, most of the characters are original, and many of the settings were made up.
If you want a faithful Pokemon story... I'm afraid this may disappoint fans of the original.
I apologize for that.
The book has funny moments and pitfalls, explores the darkness of human nature, and praises its radiance too. Basically, you have to read it without using your brain.
