Do not expect much from this series. There's no characters or story development whatsoever, but this animation is nevertheless enjoyable. It's a cocktail of little bit of everything. You'll find lots of well drawn pro wrestling action, fantasy world premises and characters, animal love, friendship, silliness, healthy dose of non offensive fan service, even some money management suggestions. There's no major antagonist, and minor ones are not evil or scary.
If by any chance you've watched How Heavy Are The Dumbbells You Are Lifting? and liked it, you may very well enjoy this one. It's less motivating, but more entertaining.
It's the very first series made by ENGI studio (KADOKAWA subdivision) and I think they made a great start.
