1. Story was below average. Worldbuilding was near to zero, even tho there are monsters, knights and magic, we know nothing about and it felt like they has no purpose.
2. Art was colorful and nice. Animations was decent and there is not much to complain about. Nothing epic, but decent.
3. Sound was't bad, but it was forgetable. It didn't disturb any scenes tho so I'll say it's fair enough
4. Characters are not that bad and some of them are pretty good, but sadly, they wont compensate other characters, that are not that good. Main character is specialy bad and it really feels like he is walking overpowered dummy. There is no limit to his stupidity and his only personality is over the top good guy.
Overall It's not good anime and specially not anything memorable, but if you are able to completely turn off your brain, then I guess you can enjoy it. I dont have this skill and so I definitely wont recomend it
