The Strongest Suicune Comprehensive Manga

When I woke up, I became the Pokémon Suicune. Damn it, there is an upgrade system for the strongest Pokémon. If you want to become a Pokémon, why not Deoxys, Rayquaza, Ho-oh or something else? The protagonist of this book will not be transformed into a human being. I've read so many books about exotic beasts, and once the transformation appeared, I couldn't read them anymore, so I wanted to write one of my own. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
