This is like Digimon, meets Fairytale, meets RWBY. It's really cheesy monster fighting, with noble idiotic child heroes. The artstyle is very inconsistent between animation and very obvious cgi that doesn't even match. And by the power of friendship, they will defeat the villains that resemble Yugioh antagonists.
Now I'm rating this as "Mixed Feelings" because I can't exactly say this show is bad. If I were still 12 years old then I might have liked this show much more than I did. But those days are past and this title wasn't for me. After four episodes in, I didn't see a single stand-out quality to make this show shine, so I wouldn't recommend it... but if you have a younger viewer who cares more about action than content, then they might still like it.
