"Hey! Get back here!" Natsu Dragneel roared as he chased the lizardman down the corridor. His fists burning with a intense flame, he leaped forward and smashed his fist into the monster's back, incinerating the lizardman into ash.

Breathless after the running, he observed the tunnel in front of him. The exit is outlined by the light at the end of the corridor. He walked to remaining distance into the blinding light. Within the chamber, a tall pyramid stood in the center, surrounded by a moat of clear water. A single chest rested on a cushion at the top of the pyramid. Natsu held up the mission order. On the yellowing paper is a picture; it matched the chest exactly.

"Yes! I found it!" he whooped and ran toward the pyramid, jumping up the steep side of the structure like it was merely a staircase. Reaching the top, he stood before the small chest. He extended a hand and gripped the chest, lifting it from the cushion. He tensed, expecting a trap, but nothing came. Relieved, he stuffed the chest into a bag and jumped off the pyramid onto the floor.

As his feet hit the ground, his vision swayed. What is happening? Natsu dropped to his knees and gritted his teeth in agony as a burst of pain shot through his body, starting at his heart and spreading outwards. As another wave of pain passed through him, his head started to itch. His mouth open in a soundless scream, he arched his back, as if it will lessen his torment. Suddenly, sound came out of his mouth in a ear piercing scream. He immediate;y closed his mouth and gritted his teeth.

Did i make that voice? He thought to himself amid the turmoil of pain and he blacked out.

-.-.-.-

Natsu opened his eyes. The interior of the chamber has become dark except for a beam of moonlight shining upon the water around the pyramid. He guessed night has fallen outside. His thoughts drifted to Happy, who waited outside. The text on the door of the temple warned that whoever enters must do so alone; or the temple will self destruct. He wondered what had happened with the painful spasms he had before.

With a light sigh, Natsu slumped forward and his hair fell to form a curtain in front of his face. Wait, hair forming a curtain? Natsu sat straight up. He reached around his back and grabbed his hair. It had extended past his shoulders. Suddenly suspicious, he spoke to hear his own voice. A feminine voice echoed in the chamber of the temple. This cannot be. His hand ran down his front and touched his chest. Instead of the hard muscles from years of action, his hands met soft flesh. No...

Natsu dashed to the water and looked at the reflection. Staring back at him was not his familiar reflection. Instead, he saw a pink haired girl with eyes of liquid black. His white scarf became thinner and narrower, made of a partially transparent silk with intricate embroidered designs. His attire on his upper body consists of a jet black bikini top, with his open chest jacket outside of it. The jacket became smaller and of more flexible material.

Natsu has become a girl. She dropped to the floor and covered her face. What will she do now? A surging wave of emotions of emotions crashed over her and she curled up, weeping.

-.-.-.-

Natsu staggered out of the temple. A torrent of rain poured over her as she left the shelter of the building. A shape flew out of the trees in the forest around the temple and aimed toward her, yelling in a familiar voice.

"Natsu!" Happy flew over to her and hung in the air. As he got close enough to see her, he froze. "Natsu...is that you?"

Natsu nodded slowly, the rain running down her hair and face. It was as if she was crying. She walked over to a tree and sat down, ignoring the wet ground. She pulled her legs toward her and put her head between her knees. Happy hovered worriedly by her head. "Natsu, are you okay?"

She said nothing for a long time. The rain dropped to a drizzle. Finally, Natsu lifted her head and looked at Happy. "Happy...will you stay by me, even with me like...this?"

Happy looked annoyed at the question. "Of course, Natsu! We're friends aren't we?" He crossed his arms and nodded.

The pink haired girl studied at her hands, which had become slim and lighter in color. "I cant go on like this. Igneel named me Natsu because of my gender and personality. It means summer. I...can't use that name anymore." She looked Happy in the eyes. "I need a new name."

Happy tried at a attempt at humor. "How about Natsuna?" he suggested. Natsu managed to crack a smile. She shook her head.

"If you agree," she began,"how about Natsumi?" She tossed her hair and fluttered her eyelashes. "It means summer beauty. I'm worthy of the name, right, Happy?" They looked at each other and laughed. Natsu felt the warring emotions within her calm and recede. It would be all right.

Happy spoke up again. "Natsu, did you finish the mission?"

Natsu nodded. She untied the bag and lifted the box out. She noticed her hands had grown smaller. She could no longer hold the box lengthwise with one hand easily now. "Shall we go home?"

Happy agreed. "I can't wait to see the looks on their faces when you come back!" The cat put both paws to his mouth to hold in his laughter. Natsu smiled and swatted him. She stood up and shouldered the bag. With Happy behind her, she started the long walk back.

Notes: I hope you like my new story :D I thought i would be weird to just change Natsu's name in the middle of the chapter, so I'll start calling her Natsumi when I next update the story. Please review and suggest. All your ideas are welcome!
