MASHIMA FANS, STAND UP! After the OG that is Rave Master, the wonderful adventurous story of Eden's Zero, and of course, the popular and 'critically acclaimed' Fairy Tail, we've got another Mashima involved work to enjoy. Although he wasn't in charge of the story, and only drew up the character designs, you will still feel that sense of 'Mashima wonder' breathed to life through the anime (I know I'm glazing, let me do as I please). Now, as for the anime itself, I'm going to keep it a stack...it could have been better for sure. In all honesty, you can easily tell that it's only apromo for the game, and not some intensely made project.
-the story really isn't all that great
-the fights are mostly one-dimensional
-the animation is decent at best

So why am I recommending this anime to you, regardless? Simple. Because it's a fun anime to watch, especially if you are a fan of Mashima's other works like I am. In fact, the sole reason I watched this show in the first place is because I heard he was involved, even if it was only for the character designs. But that doesn't take away the fact that I genuinely believe people can still enjoy this anime, and what it presents.
-the characters themselves are fun, and although they share many similarities to Mashima's characters, I don't see that as a bad thing at all
-the comedic timings are great, especially since the studio that made this anime has worked on Fairy Tail in the past (Fairy Tail humor is hilarious, that's just common sense)
PS: for those that have problems with Mashima's overuse of fan service, this anime avoids it, so you'll be fine.

So don't knock it down because of the harsh score, and just give it a watch!
