As overpowered, as overpowered go. So much so that I would rate lower if that's the basis. But hey, I actually liked the characters so I enjoyed the whole thing! MC's appraisal skill became so overpowered he can predict moves AND copy all skills/spells simply by appraising. This happened because his eye is made up of the core of Yuri, one of the nine spirits of yggdrasil scattered around the world. In exchange, he promised to reunite Yuri will all her sisters. And every sister they find, they turn into a companion. So 9 sisters... You'd think that's a HUUUGE number of characters to collect. But wait tilI tell you, every yggdrasil spirit has a guardian. So multiply that by 2 😂 Include a king, a princess, a merchant, guild master, townspeople, villains, and goodness, there are so many characters in this anime! 😅

I also like the art. Most of the characters are pretty and unique in their own way. My personal favorite is Ursula which we meet very early on.

All in all, i recommend this to fantasy/isekai/op-mc lovers!
