User blog comment:IamJakuhoRaikoben/Chapter 449: Mavis & Zeref, Review./@comment-4933386-20150824131731

I'm not too hype about the chapter as I was couple chapters ago where they introduced new characters and magic.

The first part was a pretty much a recap of FT0 which wasted a lot of the pages :( And the Mavis and Zeref was a meh for me... only thing worth watching is that Mavis is cursed with Zeref.

I guess Fairy Heart is some sort of Ultimate fairy Magic that Mavis used to seal herself because it is stored with a the Death Magic that Zeref possess. That way it won't be unleashed unless it's released. So Mavis technically didn't die... her body was just in a form of the Fairy Heart

But at the same time, I don't get why Precht called it "light" during the time he tell Natsu and that to tell Makarov about releasing it. While Ivan called it the Fairy's Darkness.

If it is contained with the Death Magic Zeref also possess (or side effect of the immortality), Makarov wouldnt even dare to release it and tell Mest to erase everyone's memory of it once it's done, because they'd be dead if they're in the vicinity.

Fairy Law kind of makes a bit of sense in that it's similar to Ankhseram Magic, it can kill someone in its vicinity, similar to Zeref's death magic but Fairy Law is subjective based on the user. then wtf is Grimore Law? So far, all we know about Fairy Heart, is that it has a great amount of power (light or darkness? Hm, both?) that could destroy every Etherious (probs spelt it wrong) and that Zeref really wants it. Perhaps Zeref gave her that body so that she can supress the curse she has?
