3:30, somewhere in Tokyo
"Stupid teachers," Shinji mumbled as he rode home from school. Not only had he failed a Trigonometry test, he had received 3 detentions- in one day! "Mom's gonna have a cow…" He never was a troublemaker, just a prankster. As he rode his bike around the corner, he heard an explosion. He looked over his shoulder to see a girl be flung across the street like a rag doll and slam against the brick wall. "What the hell!" he cried as he dropped his bike and ran to her side. She wasn't moving. "Hey…hey are you okay?" he asked as he shook her shoulder lightly. She twitched, which sent a wave of relief through Shinji. At least she was alive. When she opened her eyes, she gasped. "H-help me…" she whispered. Her voice was soft but weak. She needs medical attention-NOW!, he thought. He was careful as he picked her up. She was light but solid. She opened her eyes for a moment and smiled weakly. "I always knew you'd come back for me, Yoru…." She closed her eyes but the smile stayed on her face. She leaned against his shoulder. She gave off a tremendous amount of heat."Hang on; I'll get you to a hospital."
Fukushima Central Hospital
Shinji waited patiently for the doctor. When the doctor finally came, he told Shinji what happened. It was a slow day, so all sorts of help were available. IV's and bags of fluids had no effect, though. At 4:07, she was pronounced dead. Shinji was horrified. He had never known anyone that had died, much less a girl that beautiful. As he slowly rode home, he thought about the day's events. He didn't even listen to his mom as he went upstairs and crawled into bed.
Shinji's room, 12:04 A.M.
The window to Shinji's room opened. In entered a thin figure. The figure looked around, and crawled into bed with Shinji. The figure wrapped its arms around Shinji's neck. Shinji's eyes opened and stared into the eyes of the dead girl, now clearly very much alive. He stared for a moment, and then screamed. She quickly covered his mouth with her hand and motioned for him to stay quiet. He noticed that she still gave off the same heat, so she couldn't be dead. When she removed her hand, he stayed quiet for a moment then whispered, "What the-!" he was cut off as she kissed him. It was a deep, loving kiss. It felt so natural; Shinji put hand on the back of her head. She seemed to enjoy this, but she pulled back."I knew I would find you, Yoru!" she cried. "You said that before," Shinji said. "What does that mean?" She giggled as if it was a joke. She curled up in the crook of his arm. "I'll explain it to you in the morning, my love…" she said sleepily. She was soon fast asleep. Since there was nothing more he could get out of her, Shinji went back to sleep. Thank God mom knocks before entering, he thought.
When he awoke, she was at his computer, looking at…"H-hey!" he cried as he realized she was looking through his "favorites". "Oh, you naughty boy! I had no idea you were into this!" she laughed. "What are you DOING?" he asked as he switched off the monitor. "Just looking…" she said with an honest-looking pout. Shinji smiled to himself. She was cute in the light, when she wasn't on the verge of death. She smiled, sending waves of happiness through him. Suddenly, a thought hit him. "Oh,hey," She looked up at him. "you called me 'Yoru' last night. Why?" She walked up to him, slipped her arms around his neck and kissed him. This only momentarily surprised him. He then slipped his hands down her sides. She giggled. As they kissed, her body began to shimmer though Shinji took no notice. Her head tilted up as it grew to a bullet shape. A tail grew from the base of her spine. Soft, thick yellow fur grew from her body. Her fingers contracted and fused to create 3 toes. Her ears shifted and stretched as they positioned themselves on top of her head. As they broke, Shinji opened his eyes. He was surprised. "W-WHAT THE…!" he yelped and fell backward onto the bed. "Relax, this"-she gestured towards her body- "is my true form." Shinji processed this for a moment. She was able to change her appearance. So she was a Shifter. Or a Changeling. "Would you explain just what the HELL is going on!" She smiled, if you call a twitch across her face. "Very well, I've put it off long enough. Shinji," she looked him square in the eyes, "My name is Renamon. I come from a world called Vyvernia. You are the Keeper of the Soul Blade, the most prized weapon in all of Vyvernia. You are destined to save the worlds we both live in."
