Hey everyone, I am not new to fan fiction but I am new to Inuyasha so bear with me. Yes, I am a horrible speller and no, I do not own Inuyasha, just this plot.

Just so we're clear, I love Inuyasha but I put him the bad guy this time, and I promise there will be more romance then you think! And, I'm not sure know if Inuyasha needs the whole jewel to become a true demon but just for this stories sake, please pretend he doesn't.

Chapter 1

Inuyasha and the Demon Within

"Kagome! Be careful!" Miroku called as he leaned over a badly wounded Sango. "He isn't himself!" Kagome ignored him, holding tightly to the sacred jewel shards in her pocket in reassurance and inching her way to the red-eyed, half demon.

Inuyasha was standing, his back slightly bent with blood dripping down his claws and making a puddle in the grass beneath his feet. The War demon was lying a dead a few inches away, the three shards of the sacred jewel was scattered on the ground.

No wonder it had been so hard for Inuyasha to handle, three shards? Kagome thought to herself as she took another hesitant step to him. The Tetsusaiga had dug into the trunk of a tree a few feet away when the demon had knocked it out of Inuyasha's hands, leaving him completely defenseless. That's when it had happened.

"Inuyahsa. . ." She whispered only to get a warning growl as a response. "Sit boy!" She shouted. The beaded necklace pulled downward in it's regular movement to seat the half demon faced first, but this time, the necklace snapped, the beads spiraling every which way. Kagome gasped in surprise.

"Kagome!" Miroku called in worry, knowing that she was in trouble. "Get out of there!" Oh no! What happened? Kagome thought desperately, feeling her pulse increase with fear.

Inuyahsa chuckled darkly, turning away from her and leaning over the remains of the demon. He picked up the shards of the jewel from the ground and examined them in his hand. "In-Inuyasha?" She whispered.

He looked at her over his shoulder, spinning around so they were face to face. "Please Inuyasha" She wanted him to hear her, wanted to see those golden eyes instead of the fiery red but he was too far gone, and she knew it.

He gathered the three shards in his hand and then thrust them to his chest. "Inuyasha!" A pinkish glow erupted from the spot his heart should have been and then the shards sunk through his kimono, and then through his skin.

Inuyasha leaned his head back and howled in both pain and pleasure. His already long nails became longer, his muscles became toner and Kagome watched in horror as the veins in his arms and neck darkened to black, seen perfectly through his skin. The Tetsusaiga sheathe fell to the floor on it's own accord and the demonic aura shinned around him.

"Kagome!" Shippo screamed. She couldn't move or reply. Inuyasha laughed and then glared at her, sniffing the air.

"You have more jewel shards!" He accused. She shook her head in disbelief and took a step back. He didn't even sound like himself, his voice was darker and deeper then she had ever heard it. He was in front of her in that moment, his left claw wrapped around her neck, lifting her up from the floor.

"Inuyasha. . ." She gripped his claw with both of her hands and tried to pry him off but to no avail. He was too strong, she could barely breathe.

"Where are the shards to the sacred jewel!?" He tossed her down to the floor, causing her to cry out in pain. "Where?!" He roared. She felt his claws before she saw them, he slashed her across the stomach, making her scream.

He was on top of her, his claws pressing her down by the neck, chocking her. "In-Inuyasha. . .please. . ." She gasped as her vision began to blacken. Maybe she was imaging it, maybe it was just hopeful thinking, but for the slightest second, he paused. The growling stopped, his hold began to loosen. . .

"Hiraikotsu!" Kirara landed as the blade knocked Inuyasha back, off of Kagome. Miroku quickly jumped off of the cat demon and gingerly lifted Kagome up, into Sango's one good arm. "Hurry Miroku!" Sango demanded , catching her trusty weapon as it flew back at her and turned Kirara around.

"Kagome!" Shippo cried worriedly.

"Go!" Miroku demanded, running the oppoiste direction, grabbing the sheathe and heading for the Tetsusiga itself. Sango obeyed, kicking Kirara into the air just as Inuyasha stood back up.

"Kagome! Kagome get up!" Shiipo demanded as he shook her shoulder. Her eyes were closed with blood seeping from her uniform shirt. "Sango!"

Sango looked down at Kagome and mentally cursed as she saw just how serious the wound was. "Hold on Kagome, please hold on!" She looked back to Miroku as he grabbed the sword and then turned to face Inuyasha.

Inuyasha was growling in anger, his claws extended, ready for the kill. "Miroku!" Sango screamed. The monk quickly sheathed the sword and held it above his head. The Tetsusaiga glowed a dark electric blue as Inuyasha touched it, sending him flying back to the ground with a cry of pain.

"Give me your hand!" Sango yelled, steering Kirara just close enough so she could reach over and pull him up.

Miroku jumped up behind Sango and with a hard kick, Kirara soared up and away from the new demon.

"Faster Master Jaken!" Rin said happily as she raced ahead, her arms outspread in the wind.

"No! Rin don't go that way!" Jaken cried, holding his head between his hands in frustration with the staff slung over his shoulder. He hurried over to her and jumped in front of her, just as she swerved to the right, missing the cliff. "Ahhhhhh!" Jaken screamed as he noticed there was no more ground beneath his feet.

"Jaken! Stop playing around." Sesshomaru said as he grabbed the collar of the imps kimono and thrust him back to the floor. Rin giggled into her hand a few feet away.

"Master Jaken, you have to be more careful, you almost fell off the cliff." She said earnestly.

"I wouldn't have if it wasn't for you!" Jaken cried, waving his arms up and down childishly.

Sesshomaru turned from their mindless chatter, catching a sent of blood in the wind. It was human, he recognized it, and there was also. . . His eyes widened in disbelief as he began fallowing the new, strong smell. It couldn't be. He thought to himself. Inuyasha's demon side isn't this strong

"Lord Sesshomaru!" Jaken cried, running over to him in worry. "Lord Sesshomaru, where are you going!?"

"Stay here with Rin." Sesshomaru said as he continued. "And if you see Inuyasha, take her and run."
