In a nutshell: A traveler transmigrates to the Pokémon World and becomes Groudon, then sets off on a journey.
The protagonist... is Groudon, after all, so they're pretty much invincible...
So there won't be much fighting, basically.
Slice of life, slow-paced.
The plot is original, though it occasionally intersects with the source material.
The protagonist's gender is unknown.
So there won't be any romance involving the protagonist.
The author leaves lots of plot threads unresolved, offering only hints, so readers will have to fill in the blanks themselves.
It's in the fanfiction section, so I'm writing it purely out of love.
I'll take a break if something comes up.
