"Look Mira-nee, if Natsu had a twin sister, wouldn't she be cute?" Lissana asked Mirajane while she made some small pigtails on Natsu's hair. "Hahaha! Of course she will!" Mirajane respond while giggling. "Really...?" Natsu said while sweat-dropping. "That's so gross..." Elfman said while walking away. "Just imagine... Natsu having a twin sister..." Lissana say while looking at Natsu and then smiles. -- "Where is Natsu Dragneel?!?!?!" A girl shouted while she crashed the guild doors and started looking for the Dragon Slayer kid...
