(Chapter Four)

Dark Endymion paced the room of his throne, the pendant and the chain dangling from his clenched fist. She had kissed him! And yet, she still loved his younger twin! He stalked to his throne and the evil within his mind whispered to him. Kill him! Then you'll have your princess all to yourself once more! He shook his head roughly. No. He would do this the way he had to. He would not use any of his powers to help him. I will get her the way I should.
He might have made a vow, but his twin hadn't. Even if he didn't know that Dark Endymion even existed, Mamoru was determined that she remain his. He turned to his powers that he had gained over the years. She had done whatever he had told her to do without much explanation necessary. He looked into the portal that he had created, intent on finding out what was the matter. He would keep Usagi.
Unbeknownst to him, when he had opened the scrying portal, the dark energy had seeped through. Not a lot, not enough for him to know that it was there. But it seeped through and it was his unfortunate luck to be the spirit of Prince Diamond. The presence entered Mamoru's body. And it spoke to him. Why should she fall for someone else? She is yours, keep her. Put her under the binding spell. The one that will keep her yours forever. Mamoru's conscience bit through for a minute though. Why would he be this desperate? Usagi was his and he needn't resort to this deceitful behavior.
The scrying portal depicted Usagi, and unfortunately it showed her kissing Dark Endymion although he couldn't actually see him, he knew it was a man from the other night. He turned his eyes in pain before it showed her backing off from him. His eyes narrowed. Usagi had betrayed him, and was sneaking around his back?! As he had kept the portal open, the rest of Prince Diamond's spirit poured into him. Mamoru was now conscious of what his body now held. But his anger blinded him and he reveled in the feeling of the spirit in which he held so much power. Enough so that he could have Usagi back. He would do it! He would use the binding spell. The voice of the spirit inside him whispered directions into his mind and he followed blindly.
He soon reached a deserted temple that he had never known existed. He walked through the doors that had once been brand new and were now rotting and crumbling. Inside, there was the charred smell of a place that had burned down. He went up to the altar and he let the spirit of Prince Diamond flow through him and before he knew it, the spirit had taken over all but his mind. He chanted the spell under his breath and he noticed the star glowing in the middle of the altar and smiled. He continued to chant and it flared a dark black. The light twisted itself and became a great fire of black flames. They changed into tendrils and covered and twisted over every part of him, wrapping around him. When they dissipated. Mamoru's face broke into a smile. Usagi would be his. Forever.
He walked out of the temple and he went to where he new Usagi would be. Right under the maple tree in the rose gardens where she usually went. As he reached her. Diamond's heart reveled. He was Prince Diamond now and he would be until Mamoru's tricked mind would grow strong enough to overcome him. He walked up to her and she whipped around her eyes wide with surprise. He grabbed her wrist and led her to a small grove where he knew nobody ever went. He crushed to him and tore at her mouth in a rough kiss. She resisted for a moment, but as the magic worked she began to loosen and soon slumped in his arms. He smiled and let her fall to the ground. When she awoke the spell would be complete. He laughed and sat down on a smooth gray stone to wait.
Usagi awoke and noticed Mamoru sitting on the gray rock. She sat up and held her throbbing head. What was wrong with her? The pain in her head spread speedily across her whole body and she whimpered slightly. Her vision blurred and then her mind went blank except for one thought. That she was his, his forever. Her eyes, which had been bright and sparkling a moment before dulled and became an unchanging blue. She stood and walked over to Mamoru, her eyes not blinking and her face set. He knew the spell had worked and now nothing could stop him.
She stumbled and he caught her before she fell. Her eyes fluttered close and she fell into a deep sleep. Diamond held her against him and snapping his fingers, he transported to her room with her where he laid her down and leaped out of the room. A smile washed across his features. Finally Usagi was his. Forever. He went back to his apartment and stared at his face in the mirror, "Hmm, this body'll do for now." he mused. He stared at the photographs that lined the dresser. He noticed a certain picture that he had seen in Usagi's room, the one with his arm around her. He sneered and waved his hand over it. He could instantly see Usagi's bedroom through the picture.
She was still asleep and Luna was standing on top of her side and practically jumping up and down in an attempt to awake her. He could sense her growing panic. Luna herself had always been able to wake her before, but she couldn't even make her move an inch. He sneered and turned of the portal that he had created. Serenity would be his.
***********************************************************************
Deep in his cave, Dark Endymion's brain flashed in pain and he saw a picture of Prince Diamond. He knew he was back... But how would he find him? The little red pendant hung around his neck and he flipped it up in his hand and looked at it. He squinted, inside he could barely see it but there it was. Usagi's pendant hadn't just given this to him in trust he knew now. Inside was a part of the ginzoushou that she could never release without the help of the man she had first fallen in love with. "Usagi..." he whispered softly. The pendant around his neck glowed comfortingly.
***********************************************************************
She could feel the warmth of the morning sun shining on her face and her eyes fluttered open. The first thing she saw was Luna with a bucket of water in her mouth about to splash it all over her face. "Luna!" she shrieked. Luna's mouth opened and the bucket dropped down to the bed... And left a little bit a flood. "You're finally awake!" she sighed. "You were asleep for almost a day and I couldn't wake you!" she slumped down on her bed and Usagi lifted her hands to pick up and comfort the small cat. She suddenly realized that there were two diamond cuffs attached to her wrists that flickered and sparked in the light. She gasped. "What are these?" and tried to get them off.
Luna stared at her and her apparent distress. Why would Usagi be so distressed over a pair of beautiful diamond bracelets? Although they were very pretty, Usagi felt that there was something connected to them that she rather not know about. But as she struggled with them, her hands started to blister and she stopped. "Luna? What's going on?" she asked a little scared. Luna stared down at the cuffs and knew that there was something wrong with them. Usagi suddenly gasped. "I need to see Mamo-chan! I must!" And she began to struggle to get out of the trap of sheets that covered her. Luna stared at her. She knew something was REALLY wrong and she jumped in front of her but instead, she just leaped out of the window. Luna could see her ponytails flailing after her as she jumped from one roof to another.
She ran over to where Usagi's communicator was. Rei's face appeared on the very tiny screen. "Call the other senshi, there is something really wrong with Usagi." Rei looked extremely worried, "Alright Luna, my place as soon as possible." her face disappeared from the screen.
Meanwhile, Prince Diamond lay on his bed on his back staring at the ceiling. He could feel Usagi coming towards him and he sat up slightly. Immediately, the window burst open and a panting Usagi was diving onto the bed on top of him. He looked up into her face as she kissed him hard. "Oh Mamo-chan, it's been way too long." she snuggled a bit more and rolled so that she was leaning her head on his shoulder. He smiled, the spell had worked, and she would not even try to disobey him. Usagi started from her position. "Wha-?" she gasped. She sat up and stared around her. She noticed Mamoru beside her. Her eyes clouded in confusion. He looked up at her. Oh no! Don't tell me that spell didn't work! he gasped inwardly.
As soon as the thought crossed his mind, a shadow crossed Usagi's face. She slumped a little. Her eyes closed tight. Just as he reached for her. She fell back down on the bed next to him. "Is there something wrong Mamo-chan?" she asked dazedly. He sat up and she grabbed onto his arm. "No! No, don't leave me!" she pleaded. He could tell the spell was gaining effect although struggling against a pure soul. "Don't worry Usako. It'll be alright." he comforted her softly. Her eyes were flickering. He could see them as the dark magic that he had wrought was battling her.
He jumped up and quickly cast a sleep spell on her. He could not risk the spell being overcome. He had to have his Usako! She slumped down on the bed once again and he transported himself to the temple. He stared at the altar and he growled. There in the middle of the sacred plate was a reflection... But it was not of him. He knew it the moment he looked into the eyes. They were bottomless and they were filled with hatred. He stepped back involuntarily before he wiped the reflection away with a flick of his wrist.
He prepared the sacred incantation and the black fire whipped around his body once more. His eyes glowed a dark blue among the black flames. This time, he would put the actual fire on her. It was next to impossible for her to battle it. He murmured a spell word and the sleeping body of Usagi appeared in front of him. He bent down and kissed her again on the lips. The black fire that licked at him immediately rushed eagerly towards the other body covering her momentarily before it absorbed into her skin.
Her scream ripped through the temple and the part that was left of the actual Mamoru came through for a brief moment. What are you doing to her?! He screamed at Diamond who had taken over his body. There is nothing to fear. She is very safe although it is mildly painful. Diamond merged Mamoru back into his subconscious. Usagi's body hung limp on a pillow of air, floating at chest level. He stared down at her and smiled. There is no way she can stop this spell now that the black fire has kissed her. He gloated and snapped his fingers. There was a flash of brilliant light and he and Usagi were transported back to his apartment.
He laid her down on the bed and sat on a nearby chair to watch. After about an hour, she finally began to stir. Her eyes flew open and she started to cough violently. Her lungs feeling as though on fire. In reality, her body really was on fire, the evil black fire engulfed her heart and took over. She looked up and into Prince Diamond's eyes and he knew that now for sure, that he had complete control. She got up slowly and walked to him. "Mamo-chan…" she breathed before she fell onto his chest. He brought his arms around her and gave her a hug. "You are mine forever now Serenity." He whispered into her hair.
As he pulled back, he raised Usagi's chin up towards his face. "My name is Prince Diamond who has taken over your 'Mamo-chan's' body. You don't really care do you?" he asked her. She shook her head and he smiled. "Good, you will address me as Diamond when we are alone. But if I see you among your friends, call me as you would usually have done. Call me Mamo-chan. No tone word of this is to be spoken to anyone. Understand?" he demanded. Her eyes darkened beautifully and she stood up on her tiptoes and kissed his lips to make him know that she would do as he said for sure.
