AN: Sorry for the wait. Here's the last chapter in the last of my line of IYxYGO crossovers, unless you want another. If you do, let me know when you review, so don't be silent if you want the zaniness to end!

Chapter 6

Every Heart

Yugi/Yami and Kagome walked down the dark corridor towards a feint light.

"What is that?" Kagome asked Yugi/Yami.

"Probably another one of Kaiba's traps." Yugi/Yami replied. They had already met with a slew of Kaiba's robotic warriors, which Kagome had dispatched easily with her arrows, but now she was completely out, and had discarded her bow and quiver. Suddenly, Yugi's Millennium Ring began to glow.

"It's pointing straight up," Kagome observed.

"We must be close to where Serenity is," Yugi/Yami said. They stepped through a doorway into a room with a white light that seemed to come from all around. It was blinding. Suddenly, the door slammed shut behind them, and the floor propelled them upward at an astonishing speed.

"Yugi!" Kagome yelled, "What is it?!"

"Its...Kaiba!!" he yelled as they were slammed to the floor by the G-forces. Then, just as suddenly as it had begun, the floor stopped. Kagome and Yugi/Yami were thrown towards the ceiling, and into a new section of Kaiba's tower.

"Where are we now?" Kagome asked as she got up warily, looking around them.

"I think we are finally there," Yugi/Yami replied. They were indeed at the top. On the Duelists' Platform where Yugi had faced Kaiba months before.

"Welcome, Yugi," came Kaiba's voice from the darkness as the dome opened up, revealing the stars and the moon, glowing dim from behind the clouds.

Just then, Joey looked around. He saw Mai and Songo running towards them. "Where have you been?" he asked the young ladies.

"Busy. What about you?" asked Mai.

"We've been taking care of business," Joey replied.

"Yes, Kaiba seems to be a formidable opponent." Miroku added. "I haven't battled this hard in a long time."

"I know," Songo said, "Isn't it exhilarating? The adrenaline is flowing through me."

"I'm so gald you two have been having fun," Inu-yasha said, "But, personally I'm tired of fighting Kaiba's metal puppets."

"I think Yugi's at the top of the tower," Joey said, his Millennium staff glowing, "Let's go!" They ran as fast as their feet could carry them. Up the stairs and out onto the Duelist Arena.

"Joey! Inu-yasha!" cried Kagome as they ran onto the platform. She ran to them, overjoyed.

"KAGOME!" they both yelled happily. But as they both stepped forward, Joey turned to Inu-yasha and said, 'Hey! Back off Dog-breath, she's my girl!"

"No way! You back off, pretty boy!" Inu-yasha yelled at him. They pushed and shoved at each other as Kagome came nearer. But she ran right past them, and wrapped her arms around both Songo and Miroku.

"I was so worried about you all! I'm so glad you're all alright!" she said to her two friends, as her beaus froze and stared.

"It's not fair," Inu-yasha sighed.

"Don't I know it," Joey whimpered. Just then, Shippo appeared, in the form of a balloon, carrying Tea and Tristan to the top.

"Yugi!" Tea leaped from the balloon and ran to him. "Are you ok?"

"I'm fine, Tea," Yugi/Yami replied. " but now we must find Serenity."

"Wrong, came Kaiba's voice again. "Now you must face me." Kaiba' stepped forward out of the darkness on the other side of the platform, his arms crossed. There was a look of determination on his face, never before seen by either Yugi/Yami or his friends.

"Kaiba!" Joey declared, "You give back my sister or I'll pound you into mulch!"

"Idle threats don't scare me, Wheeler. Besides, this is between me and Yugi. Serenity is mine."

"Kaiba, this treachery I cannot forgive!" Yugi/Yami said. "You will now face the fury of the Pharaohs!"

"Yes, Yugi! That's what I wanted to hear. Let this be our FINAL BATTLE!!" Kaiba extended forth his hand, showing his Millennium Rod. Yugi's Puzzle was awaiting this. Suddenly, a beam of light shot forth from it, connecting with one that came from Kaiba's Rod. The Shadow Duel had begun. They both mentally conjured ferocious monsters of tremendous power to do battle in their names.

Serenity banged on the door of her room, shouting for Kaiba's guards to let her out. Just then, the door opened, and the goons came rushing in.

"We have orders not to hurt you, Miss Wheeler, but we can't let you make so much noise during Mr. Kaiba's duel."

"They're dueling already?" Serenity knew that she had to stop them. Ishizu, she thought, give me the strength to use this. She concentrated hard on the past, and suddenly, all of Kaiba's henchmen dropped to the ground, reliving past childhood traumas and calling for their mothers to help them. Serenity ran out of the room and down the corridor towards the stairwell. She had a long climb ahead of her, but she had to get there in time. She had to stop the terrible future she'd seen unfold: that she'd was seeing unfold before her eyes. The Necklace granted her the vision of Kaiba and Yugi's duel in her minds eye. She could see it slowly draining them both of their strength and energy. Of their lives. This was the most difficult challenge that either of them had ever faced. It was taking everything they had to conjure the mental images of their monsters.

"Just hold on, you two! Please!" she said aloud as she climbed stair after stair.

Yugi/Yami and Kaiba began to fade. Their Millennium Items were draing them of every bit of strength! This horrible Shodow Duel was killing them.

"Someone stop them!" Tea screamed, 'They're dying!" But there was nothing any of them could do. Without the power of a Millennium Item, none but Joey was able to, but he couldn't interfere. Something inside told him that if he used the Staff to stop this duel, it could possibly kill all three of them. He could only watch as his best friend slowly faded away into the Shadows.

Just then, Serenity came bursting through the stairwell entrance, screaming, "STOP!!!!" She leaped towards Kaiba, throwing him aside and breaking the chain of light. Yugi/Yami collapsed onto his knees, and Tea came running up behind him when he fell.

"Yugi, are you ok?" Tea asked, shaking him "Yami? Speak to me! Either one of you, please, just say SOMETHING!"

"T…Tea," Yugi/Yami groaned as he opened his eyes.

"Serenity!" Joey cried as he ran to where his sister sat with Kaiba barely conscious her arms. But Kagome grabbed him and said, "Wait, Joey." He stopped, and watched his sister cradle Kaiba's head in her arms.

"Seto? Seto Kaiba?" Serenity said, tears running down her cheeks. "Can you hear me?"

"Serenity?" he whispered. "Wha…What are you doing here? I…have to finish…Yugi."

"You poor foolish boy! Don't you know you don't have to prove anything to anyone? Especially not to me." she said, a sad smile on her lips.

"Why…Why are you crying for me?" he weakly asked, "I…I've done…"

"I don't care about that," she said. "I know you have kindness somewhere in that stone cold heart. You showed me that much when you refused to control my mind. You wouldn't take away my free will. You were a good person once…I know you can come back from the Darkness!" she cried as she embraced him. Kaiba looked from her to the stars above…Could he? Could he really…? He closed his eyes, and thought of how this girl, who he'd wronged so many times in the name of love, could still care for him…He opened his mouth, and as he cried loudly into the night, his stone heart broke within him…and the Light of this strange new love broke the Darkness within his mind.

As his cry died away, he felt his strength return to his battered body. He lifted his arms up, and held Serenity close to him…Now that he had her in his arms…he knew what her name truly meant.

Kaiba Corp helicopters suddenly appeared on the horizon. Moku must have sent them, he thought as Serenity helped him up.

"Ready to go home?" the young girl asked him.

"Yes," he said, as the others approached them slowly. "Yugi," he said to his former foe, "I'm sorry. I don't desreve this Item that you gave me."

"No, Seto Kaiba. You are the Millennium Rod's true possessor. And you have earned it this night."

"I don't expect that any of you will trust me, ever again...but I'd like to make it up to you."

"Well you can start by paying for this dress," Mai said.

"You won't ell anyone about us, will you?" Inu-yasha said pointing to himself, Kagome. Songo and Miroku.

"I doubt anyone would believe me." he replied.

"Then let's go home," Yugi/Yami said as the first chopper landed.

Epilogue

"So…how do you feel about your worst enemy and your little sister dating?" Inu-yasha asked Joey as they swept the porch of the Sunset Shrine.

"About the same as I feel about having to share an after school job with you, dog-breath. "

"I don't hear sweeping out there!" called Kagome's grandpa from the shop. Kagome, who was sitting under the tree, laughed with Miroku and Songo. Two months had passed since the duel. Seto had started attending school after he was well, and Kagome had gone back in time with Inu-yasha and the others since then. Now, with Summer coming soon, and the Domino students' return to their rebuilt school, she was almost sorry to lose all the excitement that her new friends brought. But with Joey as her grandpa's second official apprentice, it didn't have to end.

"I'm so glad things are back to normal," she said happily with a sigh. Just then, Joey's broom sneezed!

"SHIPPO!" The boys cried. Inu-yasha smacked the kitsune, getting a resounding cry of "Ow!"

"Yup," Kagome reiterated, "Everything's back to normal."
