"Yusuke, your next mission is to- Koenma was cut off (yet again).

"I want to know HOW you weren't touched by my Dragon of the Darkness Flame. TELL ME NOW YOU BASTARD!!!" yelled Hiei.

"Sheesh, it's my fire rat clothes, I can't get burned by flames or hurt by any normal sword." replied InuYasha.

"What!?! Damn..."

"ANYWAYS, AS I WAS SO RUDELY INTERUPTED!!! Yusuke, your next mission is to help InuYasha on his quest to find the rest of the Shikon jewel." finally said Koenma.

"I don't need any help from stupid humans! No! I won't let them!" yelled InuYasha.

"Why do you want us to help them, Koenma?" Yusuke asked.

"Well Yusuke, I want you to help them because I sense that Naraku is getting stronger by the second! As I'm reading in my future book, I read that your WHOLE group gets killed by Naraku. So that's why I want Yusuke to help you because we don't want the Shikon jewel in Naraku's hands, so you HAVE TO ACCEPT, INUYASHA! IT'S FOR YOUR OWN GOOD!!!" answered Koenma.

"Will we die even if he helps us?" asks InuYasha.

"I don't know yet, but you should get Hiei, Kurama, and Kuwabura to help Yusuke also, so it would increase your chance of living. I will know the answer after 1 week of you having Yusuke helping you fight because even I don't know that information yet." replied Koenma.

"Ok, ok, they can help us. But as soon as we get the Shikon jewel completed, they are out of here!"

"Well, you better get out of here, I sense Naraku is heading for the well into Yusuke's time." Koenma added.

"Ok. Let's fight Naraku!" said InuYasha.

***********************************************************************

In InuYasha's time near the well...

"Yea, these are my friends. Miroku, Sango, Shippo, and you already met Kagome." said InuYasha.

The Yu Yu gang and the InuYasha gang now know each other (Kaiko and Botan are there also) Then Kuwabura felt a spirit power drawing near. "What the hell... I sense someone really powerful headed STRAIGHT for us!!!" said Kuwabura.

"It HAS to be Naraku, *sniff* *sniff* nobody smells that bad!" replied InuYasha.

Then they saw Naraku arrive. Naraku didn't stop though. He just kept running. "No! He's trying to run right through us, knocking us all down and escape!" yelled InuYasha.

"Not in my time! SPIRIT GUN!!!" Yusuke screamed.

Yusuke shot a huge blast from his finger and it hit Naraku at full force. When the smoke cleared, Naraku got up. (He's not in his bear-suit thing) "What... I wasn't expecting that... and who the heck are you?" asked Naraku.

"Yusuke Urameshi, spirit detective. Now we have you where we want you. Prepare to DIE!!!" answered Yusuke.

Yusuke charged at Naraku, and so did Kurama, and InuYasha. InuYasha used the scar of wind, Kurama used rose whip lash, and Yusuke used shot gun. Naraku was hit! Then at incredible speed, he punched all three of them down to the ground. Then he ran as fast as he could and he captured Miroku, Kagome, Kuwabura, and Kaiko and tied them with a special rope and he jumped in the well. All they heard was this, "I'm meeting someone strong enough to stop you, so you better hurry and save your friends! Hahahahahahahaha!!!" said Naraku.

"NOOO!!! KAGOME!!! MIROKU!!!" yelled InuYasha.

"KAIKO!!! KUWABURA!!!" cried Yusuke.

"Come on, we better go after them!" said Botan.

The gang leaped into the well. When they appeared and saw Naraku running, they went after him. When they drew near, Hiei said he was going after him. When Hiei caught up to Naraku, they disappeared into thin air. They didn't stop running though, because Kurama said he felt his energy go into and abandoned factory. When they finally got there, they saw Hiei in his full demon form kneeling to the ground not looking up. "Hiei! What happened!?!" asked Yusuke.

There was no answer from Hiei. "Hiei, do you hear me? I said ARE YOU- Yusuke was suddenly cut off because what he saw suprised him. Hiei had risen, but there was something in his Jagan eye. "Holy Shit! There's a Shikon jewel in Hiei's eye!" yelled InuYasha.

"I'll fight him.(somehow knowing the Shikon jewel's power to control someone) Hiei, let's fight!" said Kurama.

Kurama suddenly transformed into his demon form, Youko Kurama. "Since when did you learn how to do that?" asked Yusuke.

"During training." answered Kurama.

Then he lunged at Hiei. Hiei moved out of the way and puched him in the stomach. Then Kurama put out his Death Tree and moved it toward Hiei. Hiei pulled out his sword and sliced through the trees and attempted to slash Kurama in the face but it was like Kurama expected that to happen because he ducked and pulled out his rose whip and tied Hiei up. "InuYasha! Do you know how to take this jewel shard out?" asked Kurama as Hiei struggled to get free.

"Yea, hold on!" replied InuYasha.

InuYasha jumped up and pulled the shard from Hiei's Jagan eye. Then Hiei returned to his human form and fainted. Kurama let him go and ran inside to find Naraku. "Wait! We can't just barge in there! We need someone to sneak in there and see what's going on!" yelled Sango.

"Good idea! I'll disguise myself as a rat and see what is going on." said Shippo.

Shippo turned himself into a rat and ran inside through a small crack. Once inside, she ran while being quiet up next to Naraku. He looked like he was talking to two people, but Shippo couldn't see their faces. Then Naraku stood up and said, "I know you're in here Shippo!"

Then that's when everybody barged in and ran to Naraku. Then Yusuke went to look to see if Kaiko and them were okay. They were sleeping. Then Yusuke turned to see who Naraku was talking to... and Yusuke said, "Holy Shit! It's you...
