Pure - Impure: Good - Bad

Disclaimer: I do not own Inuyasha or any of the characters, (oh what disappointment)

A/N: This story takes place before Sesshomaru meets Rin, before he insisted Totosai make him a sword. It happens after Naraku makes himself a new body for the first time. The time-line isn't going to be exact, so just bear with me. Enjoy, please read and review.

Chapter 1

Inuyasha, Kagome, Sango and Miroku were facing Naraku once more, this time against his new body. Sesshomaru had shown up, fighting Inuyasha as well as Naraku. Sesshomaru destroyed Kagura with his poison claw. Sango and Kohaku were fighting against each other. Miroku was in front of Kagome, trying to protect her. The poisonous insects hung around Naraku, keeping Miroku from opening his wind tunnel. Hundreds of Naraku's demons lay in pieces across the ground. A strong blast of wind knocked everyone, including Naraku, to the ground. A demon appeared before them. He was good-looking, and almost looked pleasant. Everyone stared at him, as he smiled back at them.

There is something about this guy, Miroku thought, Something in his eyes that I don't like...

"Sango," Miroku whispered to Sango, who was laying a few feet from him, holding an unconscious Kohaku, "Take Kagome, Shippo, and Kohaku on Kilala, get away from here."

Sango started to say something, but was cut off, "No Sango," Miroku said, "Please do not argue, just do as I ask."

Sango nodded, "Right. Kilala!"

Kilala jumped to Sango. Sango heaved Kohaku onto her back. Grabbing Kagome's hand, the demon slayer took off, with Shippo safely in Kagome's arms.

"What are you doing!" Kagome yelled, "We have to go back!"

Kilala stopped, high above the others, "We can't," Sango replied, "Miroku sensed something, we have to get out of the way and let them handle it."

Kagome looked down, wondering what was going to happen. The new demon stood, still smiling at everyone around him.

"Well, this looks like it will be fun..." the demon said. His voice was soft and kind, but his eyes flashed with something evil.

"Get the fuck out of my way," Inuyasha yelled, "I have a score to settle with Naraku!"

"Who are you," Naraku asked, at almost the same time.

"You can call me Rysuke. I have decided to have a little fun with you. I wasn't far away, and heard all this commotion," Rysuke smirked, "And I was quite bored, so I decided to have a little fun."

Waving an arm around, everyone felt their bodies freeze.

Rysuke chuckled, "Can't have you messing up my spell, now can we."

The others stood rigid, unable to move or to speak, wondering what was going on.

Words flowed from Rysuke's mouth, in an almost song-like chant. The words floated up to where Sango and Kagome were flying. Kagome frowned, wondering what he was doing.

Pure has become Impure, Impure has now become Pure.

Good has now become bad, Bad has become Good.

A gray mist floated around all the guys, surrounding them, and making it hard for them to breathe.

"What is going on?" Sango asked, horrified.

"I don't know." Kagome stared down at Inuyasha and Miroku, hoping they were okay.

After a few minutes of chanting, Rysuke stopped, and laughed. Sango urged Kilala down. They landed in front of the laughing demon. He stared at them, amused.

"What did you do to them!" Kagome demanded.

"Oh, just tweaked things a bit..." Rysuke said, grinning, "Have fun..."

Laughing, he faded away, leaving Kagome and Sango looking at each other in shock. They both turned towards Inuyasha and Miroku, who were still on their feet.

"Inuyasha!" Kagome yelled, running at him.

Inuyasha brought his head up sharply. His eyes were red, and he had a stripe down each cheek. His teeth were longer, and he grinned, and evil look on his face.

What is going on with him? Kagome thought, stopping.

"Miroku?" Sango said, stepping closer to the monk.

The monk let out a cold laugh, and lunged at Sango, forcing her to back up. He raised his staff, and brought it across her side. Sango winced, and tried to dodge him.

"Miroku! What are you doing?" Sango screamed, "It's me, Sango!"

Miroku didn't answer, just continued to attack her. Sango held up her Hiraikotsu, blocking his attacks. Kagome watched them in horror.

"Inuyasha! You have to stop him!" Kagome said, desperately.

Inuyasha let out a harsh laugh, "Now, why would I do that, bitch?"

Kagome looked at him, shocked, What is wrong with him?

Inuyasha leaped at her, swiping at her with his claws. Kagome jumped back, but his claws cut across her face, leaving three long furrows down her cheek. Inuyasha reached for his Tetsaiga, trying to pull it out. A barrier surrounded the sword, zapping Inuyasha. Inuyasha let out a growl and dropped the sword.

H-he can't touch the sword, Kagome thought, Why?

"Heh," Inuyasha said, straightening, "Looks like I can't touch my Tetsaiga anymore. That sword is to protect humans, it will no longer let me touch it."

"But..." Kagome started, "I don't understand, what is wrong with you and Miroku?"

Inuyasha let out a laugh, "I don't know, but I feel better than ever. Now, I don't have to worry about any dirty humans. Now I can get away from all you simpering and whining. You never were good enough for me, and to prove it I'm going to kill you now."

Sango landed beside Kagome, still dodging Miroku. Miroku stood by Inuyasha, identical looks of evil on their faces.

"That demon," Sango said, "He switched their hearts. Now they are evil, and filled with hate and blood lust."

"What do we do, now?" Kagome asked, terrified.

"I don't know," Sango said in despair.

"Now...you die," Miroku said, grinning.

Him and Inuyasha lunged, going straight for Kagome and Sango. A flash of white came in front of Kagome, while a flash of purple stepped in front of Sango. Sesshomaru and Naraku stood in front of the girls, facing Inuyasha and Miroku.

What the hell is going on! Kagome screamed in her mind.

"You will not touch them," Sesshomaru said, angrily.

"If you value your life, you will leave now, and not harm either one of them." This time Naraku spoke.

Sango and Kagome stared at them in shock.

Sango and Kagome looked at each other, realization dawning at the same time.
