I can Tame everything (Dropped for now)

Gaia’s Dungeon is a peculiar place filled with beasts, monsters, unknown races, wealth, power, and death.
Willing or unwilling, hundreds of humans are sent there every month to participate in a little game made by the goddess Gaia. The goal? Entertain her. How? By clearing every floor to the last. The reward? The fulfillment of a wish.
Eric Knight, one of the humans recently summoned, unlocks the legendary class: Tamer. A class with the potential to literally tame everything.
An enormous dragon? Tamed. That floor’s boss? Tamed. A rude dwarf smith? Tamed. The beautiful elf woman? Tamed!!! That kid’s little dog? Not tamed, because stealing from a kid is bad and that dog seemed useless anyway.
*cough*

Follow Eric’s adventure as he ventures deeper into the Dungeon to tame myriads of living beings, clear bloody challenges and discover the dark secrets of this place.

His legendary, supra not-so-OP-but-still-OP cheat class will help him pave the road to success.
Driving him? The desire to resurrect his little brother, the only person he had ever considered family.
