Pokémon: Building the Strongest Sunny Day Team

Traveling to the world of Pokémon, other people start with legendary beasts or a system, but I start with only an injured Coalossal?

Lin Chen, a veteran Pokémon player from Earth, transmigrates into an orphan trainer in Viridian City. With no system and no legendary beasts, he relies only on over ten years of game knowledge to force his way into the Pokémon world!

He meets an injured sun-bringing Coalossal in Viridian Forest and receives a starter Charmander, forming a team of two from scratch and building a Sunny Day team!

"So what if I don't have a system? So what if I don't have legendary beasts?"

Looking at the Coalossal and Charmander beside him, Lin Chen says, with sunlight burning at his fingertips, "My Sunny Day team was never built on shortcuts, but by me and my partners, with flames and perseverance, forcing our way up!"
