Definitely an underrated anime, in my opinion. I think this anime was good it had decent animation, although it could be better in some scenes, but it was acceptable for me. I liked the story, and I wasn't aware that a game existed for King's Raid, so I didn't have any preconceptions while watching this anime. It was a little boring in some episodes, but I still had a good experience watching it. I have mixed feelings about recommending this to others because it doesn't have top-tier animation like some other anime, but if you enjoy adventure or hero type anime, I say go forit!
