I would like to present to you my newest fan fiction, a Yu Yu Hakusho/Inuyasha crossover: Through the Ages! Please note that the fan fiction, The Newest Mission, has been cancelled.

Disclaimer: I do not own Yu Yu Hakusho or Inuyasha.

Kagome's House

'I really don't visit often enough,' thought Kagome to herself as she prepared to return to the Feudal Era. She had been back for about a day stocking up on supplies, as the group would soon be tracking Naraku again. Kagome carefully placed the shards of the sacred jewel in her pocket, said goodbye to her mom, brother, and grandfather, and she proceeded to the well.

Kagome arrived at the Bone-Eater's Well and took those treacherous steps that would take her back in time nearly 500 years. In her pocket, the jewel shards gleamed a bright purple.

Spirit World

Koenma was in a quandary. The ancient Shikon Jewel, which was thought to have been lost centuries ago, had recently reappeared. Such a powerful artifact could not exist outside Spirit World's boundaries due to its dangers; so naturally, Koenma had received the task of finding and obtaining it. However, he had summoned his Spirit Detectives to do the job for him.

"Now, what do we have to do, Koenma?" asked Yusuke, muffling a yawn, "I was having a nice nap."

"I'll explain it again, Yusuke, but this time, listen to me!" exclaimed Koenma, hopping on his desk, "You must find the Sacred Jewel and bring it back before terrible things happen!"

"Sacred Jewel?" questioned Kuwabara, "What's that?"

"As the name implies," began Koenma, "It's an ancient jewel that holds enormous mystical power. A single shard of that jewel could multiply a demon's power tenfold. Because of that power, we want you to find the jewel and bring it back."

"Too simple," smirked Yusuke, "I'll have this case wrapped up in no time. Where do we have to go? Mushiyori City?"

"No, Yusuke, you're going to the Feudal Era, 400 years in the past," explained Koenma.

"What?" shouted Yusuke, astounded and angered at the same time, "And how do you think we'll do that?"

"I would not call you here without that information. Just meet Botan at the Higurashi Shrine at 5:00. She will lead you from there."

To this, Yusuke muttered something unintelligible under his breath and stormed out. Hiei merely said "hn" and was gone in a flash. Kurama acknowledged Koenma and walked out. Kuwabara was the last to leave.

"I hope they can do it," pondered Koenma, turning in his desk.

Feudal Era

Kagome had met up with the gang, and they had decided to spend the night at Lady Kaede's village. It was still daylight, and Inuyasha had gone off into the forest. Miroku, Sango, Shippo, and Kagome remained with Lady Kaede.

Present Day Era

"Are you ready to go back in time to the Feudal Era?" asked Botan of the detectives, "Let me warn you now. Koenma intends to make sure you cannot fail this mission. I am forbidden to open the gate to allow you back into this world until you have the full Shikon Jewel."

"But how do we find this jewel?" asked Kurama, "Will it be glaringly obvious?"

"Oh! I almost forgot!" exclaimed Botan, throwing Kurama a round compass, "That Spirit Detective Compass has been modified to locate shards of the Shikon Jewel. You can use it to find the jewel shards."

"You almost let us go back without that important information?" glared Yusuke, an angry face upon him.

"Meow," giggled Botan with her cat face, as she walked into the Bone-Eater's Well, "Follow me."

Bone-Eater's Well

"This is the gateway to another world?" asked Kuwabara, staring around at the dark, dank place that would supposedly take them back in time.

"This is definitely it," said Botan, kneeling on the ground as she began to course with energy, "OPEN!" At Botan's behest, the room began to fill with blue energy and the well gleamed blue.

"Now go through the well," said Botan, "And good luck."

Yusuke, Hiei, Kuwabara, and Kurama jumped down the well, unaware of what they might find on the other side.

Bone-Eater's Well Feudal Era

The Spirit Detectives had arrived in the Feudal Era via the Bone Eater's Well, and they were inspecting their surroundings.

"Well," said Kurama, taking out the Jewel Compass, "I suggest we find these jewel shards as quickly as possible."

The compass began to glow blue, and then pointed due North, in the direction of Kaede's village.

"Hiei, can you tell who has the shards?" asked Kurama, turning to his demon companion.

Hiei turned away from the fox, and opened his Jagan Eye. The eye began to glow, and then it closed.

"Yes, I can tell, fox," said Hiei, "It appears that they are three humans, a fox child, and a cat demon. They have two shards."

"Well, that doesn't sound difficult at all," said Yusuke, "Let's go get this mission started!"

Lady Kaede's Village

"I wonder what's taking Inuyasha so long," said Kagome, to no one in particular, "He's been gone an awfully long time."

"You know how Inuyasha is," said Sango, "He'll make it back eventually."

Then, their senses snapped to attention.

"Did you feel that?" asked Miroku, running up to the girls, "I sense two sources of demonic energy, and two other sources of spirit energy. They're coming our way and fast!"

Miroku took out his staff and stood in a fighting stance. Sango drew her Hiraikotsu, the large boomerang weapon, while Kirara changed into her large demon form. Then suddenly, the Spirit Detectives stopped in front of them.

"Are these the ones?" asked Kurama, turning to Hiei for his answer, "The ones with the shards?"

"Hn," nodded Hiei, "They have the shards, and it does look like they intend to fight us. I say we kill them and take the shards."

"Hiei, we should avoid bloodshed if it's necessary," said Kurama, "Yusuke, tell them why we're here."

"Yeah, listen up," said Yusuke, turning to Kagome and her friends, "We're going to tell you once: give us the jewel shards."

"No way," refused Kagome, "We worked hard to get these and we're not going to give them over to two demons."

"We didn't ask you if you wanted to give them to us," said Hiei, drawing his katana, "We demanded it." Hiei looked at Kurama; Kurama nodded. Hiei rushed for Kagome, with katana in hand, and stopped inches away from her neck.

"Don't get yourself hurt," smirked Hiei, "Give us the shards."

"KAGOME!" exclaimed a voice from out of nowhere. The Spirit Detectives traced the direction of the noise to see what appeared to be a human, but with dog ears and claws in the sky above them.

"IRON REEVER SOUL STEALER!" exclaimed the dog demon, aiming for Hiei, who easily dodged the attack.

"Who are you?" asked Inuyasha, turning to the Spirit Detectives, "And what do you want with Kagome?"

"Don't concern yourself with who we are," smirked Yusuke, "And we don't want Kagome; we want the jewel shards. And we'll take them, by force if necessary."

"Just try it!" exclaimed Inuyasha, drawing his Tetsusaiga.

'Incredible,' thought Kurama, 'The sword nearly doubled in size. What's going on here?'

"Kurama, think this over later!" exclaimed Kuwabara, as Inuyasha swung at them with the Tetsusaiga.

"Wind Scar!" yelled Inuyasha, as the blast of energy escaped his sword, and headed towards the detectives. It appeared as though Inuyasha was successful, that the detectives had indeed been caught up in the blast.
