Okay lets begin with the first chapter.
In the first few pages we are introduced to two of the main protagonists of this shit, Lucy A celestial spirit mage and Natsu a dragon mage. Any fan of Hiro previous work RAVE can see these one of the designs are a rip-off of the one heroes of that series Haru. Natsu is basically a red haired Haru except more annoying but we will get to that later and don't think this is the only charterer design straight from RAVE there many more. We also get the see the pseudo mascot of the series Happy, a cat with tiny little wings on his back. Happy is nothing but a gag character whos entire shtick is to be annoying and cute but is so annoying and not funny to the point that you just want to gouge its eyes out and curse every time he on the screen.
During the first chapter Lucy wants to join the mage guild Fairy Tail, basically a fraternity guild of the mage world. A guild thats filled with the hottest and strongest mages around. And spoilers guess what Natsu is a member of this guild and at the end of the chapter Lucy joins too.
As I said Natsu is a dragon mage, basically he was adopted by a fire dragon who he considers his father named Igneel who taught him magic known as dragon slayer (the rarest magic) who disappeared one day like 07/07/07, his dream is to find his father. Natsu is a prime example of everything wrong with a shounen protagonist.
Lucy (who most of the time is basically a walking piece of fan service) uses keys to summon spirits to do her fighting that include: A mermaid that drowns everything including her owner sometimes whos tsundere and doesn't like Lucy, a scorpion with scissors, a Minotaur with a mace like weapon who dates the mermaid chick and others that I'll talk about later. Lucy dream is to write a book about her tales in Fairy Tail (get it).
Soon we are introduced to fairy tail and there guild members who outside of like the main cast hardly do much in the series at all. As I said fairy tail are like a fraternity were they basically do nothing but party and get into fights at there guild.
But during this we meet the other two members of the main group. Erza and Gray, two other characters whos designs and part of there personalities are ripoffs of other superior characters from Rave: Musica and Shuda. Gray is an ice mage who manipulates and generates ice and has an annoying rivalry with Natsu. He also has a stupid gag where during battle and such he strips off his clothes (its explained why later on) but it serves no other purpose but then to be a lame gag an cheap fan service. Erza is a walking boring mary suu in which her powers are like Lightning from FF13LR where she changes her armor for different effects and are just as fan servicey as lightnings.
Those other characters are:
Elfman: who out side of one moment in the third arc does nothing else through the rest of the series and if he does it gets shat upon. He is a beast man.
Marc something: who is the guild master and the old shounen troupe of the old badass. Except he is anything but he gets jobbed every time we see him fight I mean Vegeta and the Lieutenant from Korra don't get as jobbed hard as him. He grows big.
Cana: another walking piece of fan service who is barely relevant until a later arc and doesn't do much afterwards. She gets her bullshit power from a bullshit deus ex machina ghost later on but will get to that stupidity later.
Gajeel: An Iron dragon slayer villian turned good guy whos honestly one of the better characters but gets the shaft most of the time and badly to.
Laxus: Grandson of marc something who is an artificial dragon slayer of lightning, who is the best character of the series but Hiro ruins him in the worse arc of the series.
Mirajane: Elfman sister and like the bartender of the series who has a former rivalery with Erza who through out the series has build up and when its reveled its really nothing at all. Her power is to transform into a fan service demon and she later gets into a suit suit competition during a tournament arc (screms).
I liked this series early one because it had alot of promise; but to me it stopped growing the series became stagnate.
Such poor world building, the characters never change, its not funny, the women every single one of the outside of two have ton of fan service for no purpose other then to get people rocks off and are also objectified for cheap laughs sometimes, he fights are boring because Hiro has no idea how to build tension, there deus ex machinas all over this series to even Bryke would say man thats to much, there are no consequences to anything these characters do, entire plot points waved off and never comeback or handled so poorly your like "Seriously", small character moments are ruined by cheap gags or fan service, those side characters most of the time do nothing outside of there gag, there homages/ripoffs from other series through out this manga and everything in this series is solved by friendship/deus ex machina.
I haven't even gone past the first few chapters (other then talking about some of the characters a little).
