Fairytail's strongest team was walking back to their guild. A pink haired young adult was walking, with smoke rising from his head. "I told you it wasn't going to work, you flaming, pink fuzz ball." The blue haired man said, failing to realize he was only wearing his pants. "Who are you calling fuzz ball?! You naked freezing loser!" the pink haired boy shouted back. The blue haired by looked down and shrieked in shock. "Oh not again!"
"Natsu! Grey!" A red headed women glared at them both. Suddenly they both calmed down and glared at each other as they pretended to be friends so she wouldn't hurt them. "Sorry Erza" Natsu smirked. "Some things just never change" A blond haired girl laughed, as she watched the whole thing. "Aye" said the blue flying cat as he landed on her shoulder.
Natsu kicked the door open and shouted "we survived!" Everybody in the guild turned around as the strongest team walked back. "Hi guys how did it go?" shouted Mirajane. "Yeah we did great!" Lucy smiled as she waved at her. "Until Natsu stupidly did…." Grey was interrupted as Natsu tackled him to the floor. "You were going to do it too!" "Yeah but I wasn't going to destroy the whole castle in the process!" Grey screamed as he kicked Natsu off him.
"Natsu! Grey!" Everybody in the guild stopped what they were doing and saw the master standing at the top of the stairs. Both of the boys stood up and looked up. "We're sorry" mumbled Natsu. "Yeah, sorry gramps" Grey said.
"Come with me" Gramps ordered. "You two are really in for it now" chuckled Cana, as she lowered her barrel of bear. "Yeah a real man wouldn't fight like that!" shouted Elfman. Natsu and Grey ignored them both and walked into Gramps's room. The small man was standing by the window, with a thirteen year old girl leaned beside the window, looking out to the view.
"Boys this is Mortis she is our newest member of the guild" Gramps explained. "Nice to meet you, I'm Natsu" he smiled. The girl looked over and said "ok." Natsu stood back a step and shouted "WHAT'S YOUR PROBLEM! I'M JUST TRYING TO BE NICE!" He had fire raging all around him. Grey threw Ice at him and pinned him to the wall. "Ignore the jerk. Gramps, why have you call me and Nastu here?" he asked.
Natsu melted the ice and walked back next to Grey to listen to the master. "Mortis has two magic abilities. The two shouldn't be possible together" he explained. "What magic abilities does she have?" Natsu asked. Mortis turned around breathed out forcefully out of her nostrils. Fire blew out of one nostril, while ice blew out the other.
Both Natsu and Grey let their mouths fall to the floor. "What the hell!" Natsu shouted. "Wow! How is that even possible?" Grey asked. "This girl has a lot to explain to you both as her past connects you all together" Gramps explained. Mortis turned around and stared at them both. "Where did you learn Ice magic?" Grey asked. Mortis looked worried as she knew the answer will affect Grey profoundly. "What?" he asked. "Ur taught me Ice magic" she said.
Grey stood back a few steps. "What!" he shouted. "No! Your lying. Ur died fourteen years ago. You're too young!" he raged. Ice was forming over his fists. "Grey let me explain. I have a curse as well as two gifts. I can speak to the dead. Ur came to me four years ago, she offered to teach me ice magic I said yes and she has taught me everything I know." Grey had tears running down his cheeks. "No you're a liar!" Grey shouted as he stormed out of the room.
"Leave him to his ice pebble to calm down" Natsu smiled. "Natsu what Mortis has to say next will affect you like it has done to Grey" Gramps warned him. "Natsu. Your name is Natsu Dragneel yes?" she asked. "Yeah I named myself after my father Igneel" he smiled. "Just as I did four years ago" she said, sadly. "Huh?" he asked. "Natsu Dragneel. My name is Mortis Dragneel" she explained. "Wait, what?" he asked. "Four years ago a dragon found me wondering in the woods. He took me in and taught me fire magic and taught me to read, write and told me about the guilds. He told me to join Fairytail when I was ready" she explained.
Natsu just stood there staring at her. "Why did he tell you to join us?" Gramps asked. Mortis closed her eyes and said "because he told me about a brother. An older brother with pink hair. Natsu I know Igneel taught you, but he told me that you and me are biological siblings."
