This is my first review.
Story: 8/10. The story is really simple, a magic world with powerful forces such the Magic Emperor and the Magic Knights, and the MC and his rivall aim to become the Magic Emperor. If you like Fairy Tail and Naruto, give it a chance.
Art: 5/10. The weakest point so far, the really is fair creepy compared to the manga art, the characters were a bit uncharacteristic compared to the manga counterpart, especially Mars.
Sound: 7/10. Decent soundtrack, looks like medieval songs, consistent with the story setting. Someone voice actors are good, especially Yuno voice actor. The MC voice actor is good, but
does not match the character. The ending theme is really good.
Character: 6/10. Decent characters, but the lack of development is notable, but it's only 27 minutes.
Enjoyment: 8/10. As a reader of the manga, I really enjoyed myself, and I was excited to see one of my favorite manga animated, but I was a bit disappointed.
Overall: 7/10. It was good, but not so much. Recommended only to manga reader.
