Great world building!

I actually never expected myself to be invested in this series but look at me now. I was introduced to this series when I saw a fan translation of the manga on a forum, the introduction was kinda generic but what keep the series afloat for me was the character interaction, up until the Irregular encounter I never thought about this series that much. When the first major enemy was introduced I was completely hooked! Using story book characters as irregular encounters was genius! Not to mention their powers are based on their stories and legends. I blitz the manga in a day and was hungry for more content so I searched the net for the source material and I found this place. I'm not as good as reading japanese as I am speaking so I had a hard time since there are no official english translation for the work so I just used MTL. I know this series was good but I didn't know it was THIS GOOD. No seriously the world building was amazing and the power progression is quite reasonable, not to mention the way the author uses foreshadowing to the future events several chapters apart was One Piece level of foreshadowing. The only thing I that would make this series a tier above others for me is if they include something like a World Cup or any international competition. I like the concept that Monster Coliseum provides I just hope it gets expanded. I would like a concept like Gym Battles and so much more. I really like that their are regional variants for monster like how a Cu Sith from Japan is a lot less stronger that Cu Sith from their country of origins. I also love that their are a lot of factions in this world it makes it much more alive than the rest.

I could go on for another 1000 words about the characters and themes but I would probably burn out after that so I'll just leave it here.

If I could give it a higher rating I would screw this three star system of kakuyomu.

Anyways recommended. If you can get past the slow start I swear to the Gods and the heavens above it will be worth your time. Hope it gets an English release and probably an Anime?
