Hello, everybody! darkflame's fans: Hi, Dr. darkflame!

If you do not get the above quote of insanity, you've obviously never watched the Simpsons.

Thank you all so very much for continuing to read this story! I'm only posting this chapter now because I had a request from a fan and I don't like to disappoint loyal readers. However, if I don't receive some more reviews, I may not post for awhile or I may pull the story all together. So, PLEASE READ AND REVIEW!

NOTICE TO ALL: This story, "Serena's Story: Kagome's Cousin" is one of three. That's right, I'm doing a trilogy. Keep an eye out at the end of my chapters. I may put a summary of the next is the line. K?

Special thanks to all the readers who took the time to review.

Ear-Tweak: Your idea for a Serena /Inuyasha pairing is actually a good idea! I'll definitely consider it since I don't want to just do one romance. Serena likes to play the field! (just kidding) I was also planning to have some romantic feelings between Serena and Koga.

Now, just for you Ear-Tweak, here is Chapter 10!

Chapter 10 – Serena's Change

Miroku had been watching the whole conversation between Serena and Koga, completely ignoring the fight to his left, which had become a free-for-all with everyone yelling at each other. He had started taking notes in his head at first, but quickly stopped when he saw how much Koga was wooing her.

Now Miroku was pissed-off. He had wanted to impress Serena, not just so she would bear his child, but because he was really starting to like her. When he saw Serena giggle at Koga's words, he decided that he wouldn't take it anymore. He marched over to Serena and touched her arm. She turned around and looked at him.

"May I speak with you for a moment? Alone?" He asked.

"Sure, I guess," Serena replied, a confused look on her face. Miroku walked away from Koga, expecting Serena to follow. He resisted the urge to look back and see if she was following him. He walked back towards Kaede's hut and went around the corner to the side where no one would be able to see them.

Serena watched as Miroku walked away from her. I guess he wants me to follow him. She thought. She turned back to Koga.

"I'll be right back, okay?" She said, her headache starting to return. He nodded. She ran after Miroku, trying desperately to shake off the pain in her temples again. She found him on the side of Kaede's hut. He had an odd expression on his face and Serena grew nervous when she realized that no one would be able to see them from the front.

"What did you want?" Serena asked, a little grumpily because of her headache.

"I just wanted to warn you about Koga," he said pleasantly. Oww, my head really hurts again! What is it with all these headaches? Maybe I'm coming down with something. I really don't wanna be sick right now, but I think I might throw up. Serena thought. She nodded at Miroku.

"Shoot," she said. Miroku was a bit puzzled by her statement, but he understood what she meant.

"Koga is a vicious demon. He'd no sooner kill you than look at you," he said, trying to scare Serena into distrusting Koga.

"Maybe, but he seemed to be a lot more interested in looking at me than killing me," she said, confused as to why Miroku was telling her this.

Damn! Miroku thought. That didn't work. Note to self: next time, come up with a better plan. Miroku thought quickly, then came up with another idea.

"Well, why do you think Inu-Yasha doesn't like him? He's got a thing for Kagome and he might end up killing her," Miroku said, this time playing on Serena's friendship with her cousin.

Damn Inu-Yasha! He's got everyone thinking his way. Even Miroku believes that puppy's bullshit! Well, I have a mind of my own Inu-Yasha, and if I wanna like Koga, then I'm gonna like Koga!

"Well, I wouldn't put it past him, but I don't think Koga would do that. That kind of thing is only for sad, pathetic mutts," she said fervently. Serena resisted the urge to grab her head as a fresh wave of pain washed over her.

"Well..." Miroku said moving close enough to whisper in her ear. "Think about it. Koga can't give you a normal life with normal children. But I can." Miroku ran his hand up and down her leg through her pants as he spoke. Serena's eyes went wide and she pried his hand off her leg. She shoved him and his back slammed into the side of the house. Uh, oh! She's gonna hit me again! He thought, cringing as he readied himself for the blow.

Serena raised her fist to smack Miroku when suddenly a voice sounded through her head. It was her voice, but a bit deeper than normal. Kiss him. Serena was startled. Why? She thought. You want to, so just do it. The voice said. But what about the consequences? She argued back. Just kiss him, consequences be damned! Serena realized the voice was right and moved in towards Miroku's face. His eyes were clenched shut, waiting for a pounding that wasn't coming anymore. Then his eyes sprang open as Serena made contact. He swung his arms around her waist and she threw her arms around his neck. The kissing couple turned so that Serena's back was now against the wall of the hut. Miroku pushed harder, enjoying the taste of her lips. She pushed back, making the kiss hurt Miroku's lips, but neither one of them stopped.

Sango stopped mid-word and looked around the clearing. Koga was staring at the others standing around Sango who were still arguing. But Miroku and Serena were nowhere to be found. Damn lecher. He's probably trying to score with Serena again. He's gonna get his ass royally kicked yet again. Sango sighed. I'd better go find them and keep Serena from killing him.

She walked toward the hut and heard indistinct noises coming from the side of the house. She walked toward them and gasped at the sight that greeted her. Serena had her back against the hut and Miroku was in front of her. He had his arms around her waist and hers were around his shoulders. And they were kissing each other.

They parted lips and looked up when they heard the sharp intake of breath. Sango stormed over to them and grabbed Serena's arm. She pulled her friend out of Miroku's grasp and glared at him.

"What the hell did you do to her, monk? Put her under some kind of spell?" Sango shouted at him.

"I swear, Sango, I didn't do anything to her. She kissed me of her own free will," Miroku said, throwing his hands up to block his face.

"Like I'm gonna believe that, you lecher," Sango said furiously. She put her free hand up to hit him, but at that moment, Serena jerked out of her grasp and Sango stumbled backward. "Why did you do that, Serena?"

"Why don't you just leave us the fuck alone, you meddling bitch!" Serena shouted. You should kill Sango for interrupting your beautiful moment with Miroku. The voice that had told her to kiss Miroku said. She ignored it with only minor difficulty and then whirled around when she heard another loud gasp.

All of the others had followed Sango and arrived just in time to hear Serena's comment. Now Kagome, Shippo, Miroku, Koga, and even Inu-Yasha stared at her, their mouths hanging open. Sango's expression mirrored theirs for a moment, then she recovered from her shock and grabbed Serena's arm.

"What did you say?" Sango hissed. GET AWAY FROM HER! The voice in her head shouted. She shook her head slightly and tugged against Sango's grip. "Oh, no. You're not going anywhere until you tell me what you said."

Serena growled, then scratched Sango's arm and twisted out of her grip.

"I said to get the fuck away from me!" Serena screamed, backing up away from Sango. The others continued to stare at her slack-jawed while Sango clutched the small, bleeding scratch on her arm. Inu-Yasha finally recovered from shock.

"You're out of line, Serena. Apologize to Sango right now," he said forcefully. Serena turned to him, pissed-off and it was definitely showing on her face.

"So now the mutt wants to pry into my personal life too?" She screeched. Inu-Yasha growled and started toward her. KILL HIM! KILL INU-YASHA! The voice screamed.

"Everyone STOP!" Kagome shouted. They all looked at her. "Let's all calm down and figure out what happened without arguing." The others nodded their approval, except Inu-Yasha and Serena, who were still staring at each other, their eyes narrowing and Koga, who seemed uninterested in anyone but Serena.

"Now, Sango?" She asked. The demon slayer looked up at her, the tiniest hint of tears in her eyes. "What happened?"

Sango took a deep breath.

"I noticed Serena and Miroku were missing so I went to look for them. I heard noise from over here but when I came around the corner, I saw Miroku and Serena...kissing," Sango said, whispering the last part.

"You lecher," Inu-Yasha hissed at Miroku. Shippo and Kagome looked surprised.

"But why would you two..." Kagome trailed off as Serena snorted.

"Are we done with the third-degree? It was just a little kiss. Okay? No need to make a federal case out of it," she said angrily.

"But, Serena..." Kagome started to say. Serena put a hand up to stop her.

"I've had enough. I'm going back to the well," she said as she started stomping toward the forest. Inu-Yasha leapt in front of her.

"Are you afraid that we're gonna question you and find out that you were doing something that you weren't supposed to be doing?" He asked, mostly trying to freak her out.

"Back off, mutt." Then she went around him and started toward the trees again.

"Coward!" He shouted after her. Serena started to turn back to yell at him when another wave of pain hit her. Her headache was now too overwhelming to ignore. Owww! She thought as she grabbed her head, not realizing she had also screamed aloud. She sank to her knees, dizzy. Inu-Yasha, actually becoming concerned at her cry of pain, started to walk towards her when a bright light began to glow from her chest. It grew outward and steadily brighter until the group could no longer see Serena.

"Serena!" Kagome and Shippo called out. The gang heard a loud snap and Kagome saw something small zoom past her. It hit Miroku square in the chest. He picked it off his clothes and Kagome saw that it was Serena's hair band, which was now broken.

The light started to dim after a minute, and then it faded into the nothingness that it had come from. Serena no longer held her head in pain. She was kneeling forward with her hands on the ground. She was breathing heavily, but she seemed to be all right.

"Are you okay?" Miroku and Kagome asked at the same time.

"Yeah, are you okay?" Sango said, a bit bitterly. Serena took a deep breath, then got to her feet, her back to the others.

"Yeah. I'm fine," she said in a slightly raspier voice than before.

Inu-Yasha noticed that Serena's scent had changed just slightly and at the same time, Koga noticed it too. But Koga, unlike Inu-Yasha, had no intention of saying anything.

"Are you sure you're all right?" Inu-Yasha asked. Is he being nice? Kagome thought. "Don't need you getting sick and barfing everywhere." Guess not.

"I'm sure. Thanks for your overwhelming concern," she said gruffly, still not looking at anybody. As Serena spoke, the others took notice of the fact that her light blonde hair was now streaked with red at the bottom, but they didn't think too much of it.

Serena grinned even though no one could see it. They are taking notice of my changes. She thought in a much deeper tone than usual. She flexed her hands in front of her where the others couldn't see and quickly admired her new claws.

"If you're done passing out, we should get moving," Inu-Yasha said rudely. Serena growled lightly.

"Bite me, mutt," she snarled, subtly putting a hand on the hilt of her sword.

"Go to hell, bitch," he snapped. Serena grinned again, this time wrapping her fingers around the hilt.

"You first," she said, her voice deepening as she spoke. She whirled around, drawing her blade in the blink of an eye, then letting go of it. It flew towards Inu-Yasha's head before he even realized what had happened. He dodged it at the last second. The sword flew past him and sank into the wood of a nearby tree trunk. "Damn, I missed!"

Inu-Yasha stared at Serena, stunned into silence. She's turned into a demon! But...how?

"Oh my god!" Kagome shouted, startled by her cousin's transformation. Shippo ran behind Kagome and hid, trembling in fear of the new Serena.

"How the hell..." Miroku trailed off, taking advantage of the situation and sidling toward Sango. How could this have happened? He thought. "How could she have transformed?"

"Don't know, don't care," Koga said, dismissing Miroku's question with a wave of his hand. He didn't care about them, only Serena held his interest at that moment. She may have transformed, but she's kind of sexy this way. Maybe more than she was as a human.

Sango just stared at Serena, ignoring Miroku's close presence. Oh my god! Her headaches and dreams! This is what they were about. Her transformation was coming and they were trying to warn her. But, how did she transform? Sango thought.

Serena watched in silence as the others commented on her transformation. She curled her upper lip at them, revealing her pointed fangs.

"Scared?" She taunted in a deeper voice than normal. Inu-Yasha growled.

"Of you? Never," he said stubbornly. Kagome grabbed his arm, afraid for her cousin and for Inu-Yasha. What could do this to her? Kagome thought anxiously.

As Sango watched Inu-Yasha and Serena argue, she realized what had happened to Serena. She was poisoned! When Iokji bit her, he must have injected her with venom. That has to be it!

"Guys!" she shouted. Everyone turned to look at her. "I know what happened to Serena! She's been p..." Sango stopped abruptly. When she had started speaking, Serena had moved in the blink of an eye. Now the new demon held Sango by the throat, cutting off the demon slayer's airway. She also held Sango's Boomerang Bone to prevent Sango from using it against her.

Sango gasped, trying to draw in breath. HELP ME! She screamed in her head. Her vision started to grow dark as she lost more and more oxygen.

Everyone gasped when Serena lunged at Sango. Miroku grabbed Serena, trying to make her let go of Sango.

"GET OFF!" Serena shouted, shoving the monk off of her. He went flying to the ground.

"Let go of Sango NOW!" Inu-Yasha shouted at her. Serena smiled.

"Whatever you say, Inu-Yasha," she said. Then she spun around, letting go of Sango and her weapon. They both went flying toward him. Kagome gasped, yelling for Inu-Yasha to move.

Inu-Yasha raced toward Sango's body, trying to catch her. But he had to leap out of the path of her Boomerang Bone and he missed. Sango slammed into the tree with Serena's sword in it. The blade quivered with the impact. Sango fell to the ground in front of the tree and blacked out.

Kagura walked into Naraku's chambers. She knelt at his feet, secretly grimacing.

"You summoned me, master?" She said. Naraku nodded.

"You must hurry. Go as fast as you can. Fly to where Inu-Yasha is and save the girl Serena from his attacks."

Kagura was confused by his order, but she nodded.

"Yes, my master."

"SANGO!" Miroku shouted. Serena smirked and everyone turned to her.

"How...how could you?" Kagome asked, astonished. Shippo whimpered, worried that Serena might hurt the rest of them. Miroku glared angrily at her. If looks could kill. Serena thought, still smiling.

Koga stared blankly at Serena, not showing how shocked he was by her strength. She tossed Sango and her weapon as if they weighed nothing. He thought.

Inu-Yasha growled. If she'll attack Sango, she'll attack us all. I must protect Kagome. I have to! He drew Tetsusaiga and turned it on Serena. It transformed into its fang form and that was all Inu-Yasha needed to know.

"Inu-Yasha, no!" Kagome gasped when she saw what he was about to do. "You can't kill her."

"Tetsusaiga transformed against her. That means she is a demon and I have to protect you from her," he said determinedly. Then he leapt at Serena, swinging his blade. She slashed him across the chest and shoulder with her claws. He gasped momentarily in pain, then resumed his attack, ignoring his bleeding wounds.

Serena easily dodged his attacks, laughing at his feeble attempts.

"Is that the best you can do?" She taunted. "Come on Inu-Yasha! Destroy me with a single blast! You've done it to demons before." He growled at her.

Take the shards. Get the shards. Take the shards NOW! The voice in her head shouted. Okay, okay. She thought back. Serena set her sights on Kagome. The teenager noticed that Serena's gaze was on her and became scared of her cousin. Serena moved before Kagome could blink and suddenly, she was standing in front of Kagome.

Kagome screamed. Serena reached out toward her, claws extended. Inu-Yasha watched in horror, mistaking Serena's quest for the shards as an attack against Kagome.

"GET AWAY FROM HER, BITCH!" He shouted. He jumped between the pair and pushed Serena back with the Tetsusaiga. Then he prepared to use the Wind Scar.

Hurry up, Kagura. I can not let my pawn be destroyed just yet. Naraku thought as he watched Inu-Yasha prepare to attack Serena through Kanna's mirror. Hurry, Kagura!

"Inu-Yasha, NO!" Kagome yelled.

"Don't do it, Inu-Yasha!" Shippo screeched.

"Inu-Yasha, stop," Miroku said apathetically, his gaze fixed on Sango's limp body. Serena stood to the side of Sango which was keeping the others from being able to get to her. I can't let Serena hurt Kagome! Inu-Yasha thought.

"I'm not going to let her hurt you, Kagome," Inu-Yasha said stubbornly.

"But I'm fine," she protested.

"But Sango isn't. If Serena would attack Sango, then she'll have no problem with attacking the rest of us," he said. Sango...Miroku thought. Serena hurt Sango. None of us have a choice anymore. We must attack her to protect ourselves.

"But, Inu-Yasha..."

"No, Kagome. We don't even know what caused her to transform. It could be permanent and I'm not going to risk our lives to find out," he snarled. He's right but I still don't want my cousin to die. Kagome thought.

He raised his sword up and sniffed out the Scar of the Wind. Then he slammed the Tetsusaiga into the ground, releasing its power and sending it toward Serena.

"WIND SCAR!"

Serena's eyes widened when she saw the power surging toward her. Inu-Yasha saw the fear in her eyes and realized he had made a mistake. There was still something human within her. It's too late now. I can't take it back.

Kagome, Shippo, and Miroku watched as the power rushed toward Serena. They were surprised when she raised her arms in front of her face and screamed.

Just as the Wind Scar reached her, it was blown to the side by an overpowering gust of wind. Inu-Yasha, Kagome, Shippo, and Miroku looked in shock as the dust cleared. A female figure stood in front of Serena's still cowering form. She held a fan clutched in her hand.

"Hello once again," the woman said.

"Kagura," Inu-Yasha barked.

Koga's head snapped toward the group. He had been ignoring the whole battle for the most part, bored by it. But now he knew that Naraku must be involved with Serena. That bitch! She had even me fooled! Why didn't I smell Naraku on her? He thought.

"What do you want, bitch?" Serena snarled as she rose to her feet, startling everyone. Kagura grinned, still facing away from Serena.

"Our master requests your presence," she said. Serena didn't reply; she just grunted her consent.

"What do you mean by our? Is Naraku the one manipulating Serena?" Inu-Yasha demanded. Kagura just smiled at him.

"Perhaps." Inu-Yasha growled at the wind witch.

"What do you mean, bitch?" He asked impatiently.

"You don't need to know," she said. Then she reached her hand up to her hair.

Inu-Yasha knew what she was doing and decided to act before she could get away.

"WIND SCAR!" He shouted, attacking again. Then he snarled in frustration as a feather rose above the attack, carrying both Kagura and Serena away from them.

"Sango!" Miroku shouted, glad the path to her was finally clear. He ran toward the unconscious demon slayer. Shippo ran after him.

"Damn it all! They got away," Inu-Yasha said. Then he sheathed his sword and turned to the others. "Come on. We have to follow them."

"But Inu-Yasha, you're injured," Kagome said.

"This is nothing," he said, motioning toward his wound. Then he glared stubbornly at her. "Now, let's go."

"No. You're injured and you're just gonna get hurt worse if you don't let yourself heal first!" Kagome shouted.

"She's right, mutt. Why don't you leave Naraku to the real demons," Koga said, finally deciding to participate.

"Shut up, you mangy wolf! This is no concern of yours. Now why don't you hand over your shards so we can track Naraku down and kill him?" Inu-Yasha said, approaching Koga, who prepared to fight. Arggh! Kagome thought. Not again!

"Sit." Inu-Yasha slammed into the ground. Koga watched as Kagome approached him.

"Koga, can I ask you for a favor?" She asked. He nodded. "Would you mind looking for Serena for us? I want to get Inu-Yasha's wounds bandaged and make sure Sango's all right."

"I'd be happy to," Koga said cheerfully.

"Thank you," she replied. Koga started to leave when she stopped him. "Just one thing."

"What?" he asked. Kagome bit her lip. I'm really worried about Serena. I just want her back here so we can find a way to change her back.

"Don't hurt her. Just bring her back to us," Kagome said.

"Anything for you, Kagome," Koga said grinning. Then he rushed off in the direction Serena and Kagura had gone.

Kagome walked toward Miroku and Shippo, ignoring Inu-Yasha's moaning, his body still imbedded in the ground.

"How is she?" Kagome asked. Miroku shook his head.

"I don't know. We'd better get her to Lady Kaede," he said anxiously. Kagome nodded her approval and Miroku picked Sango up, cradling her gently in his arms. They walked back around the hut and through the front door.
