The rookie Trainer Ai You goes to Professor Oak’s Laboratory to get a Pokédex, never expecting that it will turn out to be defective.
“Beep-beep. Would you like to activate the Pokédex?”
Ai You: “Activate!”
“Beep-beep. Pokédex activated successfully. Bound to the nobody, third-rate Trainer Ai You.”
“Beep-beep. Starter Pokémon Charmander detected. Recommendation: deposit it in the PC or release it.”
“Beep-beep. Everything is to help the Trainer grow stronger!”
Ai You: “…”
“Professor Oak, can I return this Pokédex?”
“Beep-beep. Trainer, rest assured. This Pokédex is definitely not defective.”
Ai You: “…”
After traveling with the Pokédex, Ai You learns that it was chosen by Arceus.
From then on, Ai You and the Pokédex travel back and forth between different Pokemon worlds.
They encounter a world where Pokemon have gone extinct, a world inhabited only by Pokemon, and a world where humans and Pokemon have merged into one...
After adventuring through many worlds, a god-tier Trainer rises to power!
