Set after the events of Tartarus. Natsu was training hard to protect his friends, but when he's sent into a portal by a man in black dragon armor, all hope seems lost. Then he met her. A woman with long crimson hair and demonic wings. Oh boy, how's our favorite dragon slayer gonna handle devils? Maybe like everything else: by punching! Natsu x harem(obviously) Lemons included

Acnologia comes once again trying to kill Fairy Tail after the Grand Magic Games. But this time it's different as Igneel comes back and stops his attack from killing all the mages in the area. The battle resulted in the immense magic power reactivating the left over magic from the Eclipse gate sending Natsu and Happy to another dimension with Igneel and Acnologia still being alive.

What is a Hero? What is a Monster? The Hero is the one who protects the people around him and The Monster protects what's precious to it. So what's the difference? Who is right and who is wrong? Well as Natsu would say, "Who the hell cares! If becoming a monster is what protects those I care about then so be it!"

Natsu crashes into the Underworld after a beating at the hands of Zeref. Luckily Natsu survives with the aid of a certain crimson haired girl, but there are a few problems. He can't remember anything and his body has regressed to that of a child. Will Natsu survive this new world of sexy Devils, Fallen Angels and his obsessive Demon servant. (Natsu x Harem)

Natsu comes to an untimely end and now he has the chance to take on a whole new adventure can he make the best of a new world void of public magic, crazy devil girls, and a new a power he can't understand...eh Natsu can wing it right.

Natsu and Luffy had met at a very young age and formed an amazing friendship between eachother. A promise had been made between the two and they start their journey, making friends of all kinds! (Set in One Piece world; Natsu smarter and doesn't get motion sickness)
