Edens zero is copy and paste of author former work Fairy Tail and its predecessor Rave Master. I loved Fairy Tail at the beginning but later it turned really bad. Its shows the same flaws as Fairy Tail and will turn in total garbage when author wants to create another copy paste in different setting.

So we have a main hero which is like natsu x gray
rebeccaa which is lucy
happy which is... happy
we have Elise which is Erza
Justice which is Jellal


there is even more but yeah Mr Hiro Mashima please start doing hentai it will be better for you :)
