Pokémon: Evolving From Charmander To WarGreymon

My name is Hirata Shiko.

I transmigrated, and actually became a Charmander!

Fortunately, I awakened the Lying Flat System—just by eating, sleeping, and basking in the sun every day, I can level up!

But I never expected my evolution route to be so different that I can actually evolve into WarGreymon!?

………

My name is Isobe Himeko, a peak Champion-level Trainer, hailed as the greatest genius in history!

Reborn twenty years before humanity’s extinction, I’m determined to change the course of history and save the fate of all humankind!

At first, I thought I had captured a Charmander with limitless potential.

But this guy has no interest in training at all. He spends all day eating and sleeping, and even leans against my lap to bask in the sun!

Yet unexpectedly, even like this, he seems to be getting stronger at lightspeed! Before I knew it, he had already far surpassed the Legendary Pokémon and become invincible in this world!

Also, why hasn’t my Charmander evolved into Charizard?

What is that humanoid, dragon-like monster in golden armor?

That’s way too cool!
