I may be biased but this is the best book in the series so far! I've been on Team Erza since the beginning and this book finally gave us a look into why he is how he is and so much more. For that alone, I consider this the best book to date in this series!

Now that I've gotten the fangirling out of the way, let's talk about the story. I can agree with a lot of other reviewers when they say Tori was in the background for the first half of this story, but it didn't bother me. She's human, she hasn't been training in any fighting style for most of her life like the warriors in the guild have. Unless we want her to get killed early on in the series I'm happy to let her take a step back every now and then.

I love how the author built this story up and organically introduced the main character for the spin-off series that will be intertwined with this one. I'm very curious about the new heroine and all the trouble she gets into with her demon companion.

The guys were awesome as always, especially Erza! I want to know more about his background and why he thought he had no other option than to become what he became. 

The ending wasn't something I was expecting but it does make a lot of sense for the spin-off series to belong to the same guild. It'd be really interesting see how the author flips the demons-are-bad ideology this series has set up with the spin-off probably having one as a main character.

The narration was awesome! The voices were distinct enough to the point where I didn't get lost on who was who. This narrator is definitely growing on me!
