Natsu and his Demonic Harem

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
