Ai You, a novice trainer, received a Pokémon Pokédex from Dr. Oak's research institute, but he didn't expect that the Pokédex turned out to be a problematic one.
"Didi, please tell me if the illustrated book is activated!"
Ai You: "Activate!"
"Didi, the illustrated guide was successfully activated and bound to the Muggle trainer Ai You."
"Didi, I found the initial Pokémon Charmander. I suggest you put it in the computer or release it."
"Didi, everything is to make the trainer stronger!"
Ai You: "..."
"Dr. Omu, can this illustrated book be returned?"
"Didi, trainer, please rest assured, there is absolutely nothing wrong with this illustration."
Ai You: "..."
After traveling with Pokédex, Pokédex confessed that he was the one chosen by Arceus.
From then on, Ai You and the illustrations continued to travel to various Pokémon worlds.

After experiencing adventures in many worlds, a generation of god-level trainers has risen to prominence!
