Red, now a legend with many trainers and recognized worldwide, returns to his native region after his journey to become a Pokémon Master.

A journey that ends with a merciless battle on the summit of Mont Argenté against a certain trainer...

But his return was not to be as he had hoped.

A strange phenomenon seems to be appearing in the Kanto region.

Numerous ultra-breaks have begun to appear all over the region.

It is said that a certain policeman by the name of Beladonis is seeking to speak to this legendary trainer as soon as possible, to ask for his help in this matter.

What new adventures await Red alongside Beladonids?
