Natsu come back here Erza yelled. Natsu attempted to jump out a window, but Erza grabbed him and threw him at the floor. Erza requiped a mace ready to punish Natsu for destroying her strawberry cake. Natsu had his eyes closed. Erza was about to swing her mace, when Natsu's eyes shot open. And what Erza saw terrified her to no ends. What she saw were crimson orbs that seemed to radiate the darkest magic she has ever felt in her life. Natsu stood up, he looked like he was being possessed by something. Everyone in the guild stepped back in fear of Natsu. Umm Natsu Lucy said fearfully. Natsu cocked his head to the side looking at Erza. Erza backed up. Oh Natsu finally snapped have fun with that Laxus and Gajeel said as they walked out of the guild doors. What do you mean finally Markarov asked, but the two had already left. Magic blacker then the darkest night began to swirl around Natsu in a protective way. Uhh Natsu Erza said backing away in fear of the man in front of her. This magic it's from the books of Zeref the ghost of Mavis said in utter fear. It what Makarov yelled. But how has this boy come to acquire such magic Makarov pondered. All of a sudden the black magic began to take the form of a giant claw and wrapped around Natsu's arm. The claw slashed at Erza sending a huge wave of black magic destroying everything in it's path. Natsu snap out of it Erza yelled. The black magic danced in a zig zag line towards Erza. She barley dodged as it destroyed and killed every thing it touched. That's living black magic. It has a mind of it's own, but it has only been known to protect Zeref himself Mavis said. Wait Zeref had a single son, but is Natsu really the son of Zeref Mavis wondered.
