I suggest you check out the first chapter of Eden Zero, Demon. You'll be pleasantly surprised. And right away I think you'll be able to tell how it's different from Fairy Tail.I am rather curious about Edens Zero because of the apparent positive reactions but because of FT I am not sure if I should read it or not. I was not too bothered by FT's writing anyway( AFAIR in the anime at least) but it's a 6/10 at best to me. I think it was better at the beginning though.
Rave was Mashima's better series IMO. If maybe 10 volumes later the reactions about Edens Zero are still good maybe I will read it.
I read Pluto and it was pretty good, not that outstanding though. Will decide later, Bob hasn't posted yet.
