Jusenkyo Valley of cursed springs 500 years ago

In the one of the most mysterious grounds of China, a vicious battle enrages on the top of the cliff over the cursed Jusenkyo Valley. Where the half-demon Inuyasha and his comrades, Kagome the reincarnated priestess from the future, Shippo the young fox-demon, Sango the demon-slayer with her loyal companion Kilala, and Miroku the monk, are battling the evil half-demon Naraku who has sucseeded in gathering most of the fragments of the Shikon no Tama and has caused so much grief in order to obtain every single one of them in the process.

Naraku stood proudly infront of the group, a smug grin plastered on his face, "Come now Inuyasha, you don't really believe that you and your pathetic little friends can defeat me, do you?" He jeered, clutching the nearly completed jewel in his hand. Only three shards were missing to complete the jewel, "With the power of the Shikon jewel in my possession increasing my powers, you have no chance of defeating me."

Inuyasha growled angrily, flashing his fangs in an angry snarl, "That's what you think you bastard! We're gonna make you pay for what you put us through and for all the people you killed! And this time we'll make sure you stay dead!" He shouted as he raised his Tetsusaiga and charges to attack, "Take this, BACKLASH WAVE!" He leapt into the air, swung the mighty blade and a twister of demonic energy erupted from the fang blade the moment it was fully swung and launched itself directly at the evil Naraku.

The attack struck Naraku dead-on but it was deflected by a barrier. Naraku snickered, "Such a pathetic fool." Suddenly multiple tentacle vines sprung from his body, "DIE!"

Naraku launches the tentacle vines towards the half dog-demon but Inuyasha manages to dodge them with ease while destroying them in the process. Kagome and the others joined in to assist, launching spirit wards, purifying arrows, fox fire, firey claws, and a giant boomerang bone, each of their attacks destroyed one vine after another but the vine tentacles would regenerate and continue to attack.

Sango stood back to back with Miroku, "This isn't working!" She called, "They just keep reforming themselves everytime we destroy them!" She said as she sliced three charging tentacles with her sword.

"I know but there's not really alot we can do at the moment except fend them off." The monk said while destroying another charging pair with his holy staff, "If I could only use my wind-tunnel, I could suck Naraku into the void forever but those damn poisonous insects are surrounding him so I can't. Damn that Naraku!" Miroku shouted.

"Inuyasha look out!" Cried Kagome's voice. Unfortunately her warning came too late, before Inuyasha had time to find out what Kagome was warning him about several of Naraku's vine tentacles wrapped themselves around him.

"Damn it!" Inuyasha shouted as he struggled to free himself but the vines only squeezed tighter, "I... can't move!"

"Inuyasha!" His friends shouted in concern for their dog-eared companion, but before they could do anything to free him their distractions were just long enough for Naraku's fleshy vines to trap them in his flesh as well.

Naraku laughed in his throat as he watched them struggle, "Now do you understand? It's like I've said before, I only continue to grow in power. And none of you have the power to destroy me." He jeered then he turned his ruby eyes to Kagome, "Not even Kikyo's reincarnation can destroy me." He gloated smugly, "Now it's time for you all to die, starting with you Inuyasha." He turned to Inuyasha, he lifted his free hand and it morphed into a deadly looking scorpion claw with razor sharp spikes.

Everybody struggled against the vines with all their strengths, but the vines were too strong. Inuyasha thrashed as hard as he could but he couldn't move his hands to free himself nor lift his sword, 'Damn it, I can't move my body!'

An evil smirk spread on Naraku's face, "It's useless to fight it Inuyasha? Your friends can't help you and there's no one left who can save you or your friends this time." He raised his clawed arm up for the final strike, "DIE INUYASHA!" The deadly claw darted towards the helpless half-demon.

Inuyasha and the others watched in horror as the claw drew closer. Inuyasha shut his eyes tightly and turned his head to one side wiating for the attack to hit, then...

"THUNDER CLAWS STRIKE!"

Anyone, including Naraku, raised their heads at the sound of the battle cry and before they could find the sorce, multiple energy-chi blades slashed Naraku and the poisonous insects, and disintegrated the vines, freeing everyone in the process and turning the evil half-demon and his bugs into clumps of flesh.

"What just happened?" Shippo asked.

Miroku shook his head, "It would appear that we've just been saved."

Inuyasha helped Kagome to her feet, "Yeah but by who?"

"Hey Inuyasha! Looks like you could use some help!" A strong male voice called from above.

Inuyasha and the others looked in the direction the voice came from and found Kouga, the young prince of the wolves, standing on a cliff just above the battle ground. Sparks of blue energy cracked around the Goraishi on his right hand. Kouga jumped down to his rival and his friends, "Looks like I got here just in time."

Everyone was speechless, finally Inuyasha found his voice and spoke up, "Kouga? What're you doing here?"

The wolf prince smiled, "What do you think I'm doing here mutt? I came to help you destroy Naraku, duh. You think I was just gonna sit back and let you guys handle this by yourselves? I don't think so."

"Kouga, how did you find us here?" Kagome asked, she was curious as to how the young wolf leader found them.

Kouga just smiled, "Easy. Your little friend told me." Everyone followed Kouga's gaze and saw Shippo sitting on Kilala's back.

Shippo shook his head, "Hey don't look at me. I didn't tell him we were coming here!"

This time Kouga shook his head, "No not you. I meant her." He pointed to Kilala, who just meowed at him. Kouga reached up and scratched behind the big cat's black ears, Kilala purred in delight. "I asked Sango's conpanion here to keep in touch with me when we last saw each other. So that I'd know where you guys were and when you needed help."

Kagome, Miroku, and Sango smiled at their friend, "Well we're glad you're here now Kouga." Spoke Miroku, Sango and Kagome nodded.

Inuyasha stared at his rival for a while then he stepped towards the wolf-demon, "Kouga, I don't know how you found us or how the hell you got here," then a smile appeared on Inuyasha's face, "But I never thought I'd be so happy to see you again." He held out his hand to Kouga. 'Especially since you just saved our lives.'

Kouga stared at Inuyasha's outstretched hand before smiling back and firmly grasping the dog-demons clawed hand, "The feelings mutual, Inuyasha." He shook Inuyasha's hand, realizing that he had just called his rival by his name, not the nicknames that he had made a habit of calling the dog-boy.

"Ahhh! Naraku's reformed himself again!" Cried Shippo.

The group turned around and sure enough Naraku had recovered from Kouga's attack with an angry scowl on his face. "So the wolf has finally decided to join in." His scowl turned into a wicked smile, "I have to say that you just saved me the trouble of finding you and the last of the sacred jewel shards Kouga, and once I have your shards and the final shard from Inuyasha in my possession, I shall absorb you and your demonic powers into my body. Now what do you think of that?"

Kouga bared his fangs in a snarl, "Don't flatter yourself Naraku! I'd sooner be dead than become part of you! I plan on avenging my brothers' deaths with your own death, you fucking bastard!" He turned to Inuyasha with a smirk whom also had the same smile, and then turned back to Naraku. "So get it through your damn head Naraku. We're not here to bow down to your demands," He raised his right hand calling forth the Goraishi once again and Inuyasha held up his Tetsusaiga, "We're here to fight!"

Naraku narrowed his crimson colored eyes, "So you wish to die with Inuyasha and his friends and be reunited with your fallen comrades, do you Kouga?" He snickered, "Very well then. I shall grant your wish for you and as an added bonus, your friends will be joining you in the afterlife together!"

Suddenly without warning the ground began to shake and black roaring clouds began covering the sky creating thundering lightning storms and howling winds. Naraku began cackling while he elevated off the ground, an orb of red and black energy started building in front of his body, it crackled with tainted red energy as it grew larger and larger.

"What's happening!" Cried a frightened Shippo.

"Naraku is gathering all his demonic power and that of the tainted jewel into an orb of corrupted demonic power!" Yelled Miroku over the high winds while using his staff to create a small barrier around them all, "No doubt he plans to use it to eliminate us once and for all!"

Sango held on to Kilala, "That much energy is enough to destroy the world!"

Kagome grabbed an arrow from her back, "We can't let that happen!" She readied her bow and fired a sacred arrow directly at the orb, but the arrow was destroyed be Naraku's barrier, "It can't be, my arrow didn't work!"

Naraku leered down at her, "I told you, it's useless. None of you have the power to kill me and now you're all going to die!" He cackled.

Kouga and Inuyasha stood with widend eyes and blank minds, neither one refused to believe that there wasn't another way to kill this monster, but even if there was would they be able to use it to stop Naraku before they were all killed?

"There's got to be a way to stop all of this!" Yelled Inuyasha.

"I'm open to suggestions!" Kouga called back.

Suddenly Inuyasha's Tetsusaiga and Kouga's Goraishi started pulsating and emitting a bright glow, the two demons were dumbfounded by the way their weapons were reacting.

"What the hell?" Was Kouga's only response.

'Both the Tetsusaiga and the Goraishi are pulsing. Does this mean…' Inuyasha looked to Kouga then at their weapons, as if both knew or had just told the other what was going on, they both nodded. Winds of demonic energy began to swirl around the transformed Tetsusaiga and the Goraishi started aflame with fire and lightning. (Tetsusaiga isn't the only weapon that gains power after battling a powerful demon.)

"Give my regards to Kikyo, Inuyasha!" Naraku called down from his perch in the sky, "DIE YOU FOOLS!" The black orb was launched towards the two demons and their friends, but neither moved a muscle. Kagome and the others watched in total fear as the two demons made no effort to get out of the way, their focus was on the approaching black orb.

'Fire an arrow to weaken that orb…'

Kagome gasped, 'That voice… is that… Kikyo?'

'You must use your arrow to counteract the demonic energy of that orb. And when the time is right I will give you the last of my spiritual power which will only be enough to weaken Naraku and dislodge the sacred jewel from his grasp and purify it.' Kikyo's voice rung through her head, but Kagome understood what she had to do.

She reached back for an arrow, "Alright. I'll do it!" She readied the arrow into her bow and waited for when it came time to shoot it.

Inuyasha's eyes never left the approaching attack, "Ready Kouga?"

"Let's do it Inuyasha!" Kouga called back. "RAGING DRAGON TALONS!" He swung the metallic claws and a storm of fire infused lightning burst towards the black orb of destruction.

"All right here goes! ULTIMATE BLACKLASH WAVE!" Inuyasha swung the Tetsusaiga and launched spears of light with Kouga's attack.

The demonic orb collided with the Tetsusaiga's and the Goraishi's attacks, both attacks fighting off the other to over power the other. Kagome felt her senses prick, "That's it!" And fired the arrow.

The combined power of the two powerful demonic weapons and the purifying arrow canceled out the evil tainted energy in the orb and sent it back to Naraku. Naraku was astonished that they had managed to repel his own attack and send it flying back to him, but he smirked as his barrier prevented it from reaching him. Suddenly he felt an agonizing pain on his chest, he looked down and saw that an arrow surrounded by a familiar shimmering pink aura had punctured his armor and chest.

'It can't be… that's Kikyo's light… but how… how is it possible?' Naraku looked down at the jewel in his hand and noticed that it was turning from black to pink. 'No! The jewel is being purified!" The purifying power of the arrow and the jewel left him paralyzed in the air.

On the ground Kagome turned to Inuyasha and Kouga, "Now you guys! Attack him while he's weakening!"

The two rivals nodded and held up the weapons, "Let's beat him together Kouga!" Inuyasha says as his sword transforms into the Adamant Tetsusaiga.

"Ready when you are Inuyasha!" He lifted up his right hand and swirls of fiery lightning gathered around the Goraishi and the Adamant Tetsusaiga, combining both their powers as one. The Adamant Tetsusaiga became engulfed in firey lightning while the Goraishi began to crystallize in Adamant.

"The nightmare ends Naraku!" They shouted lifting their weapons, "ADAMANT DRAGONS FIRE BARRAGE!"

They swung their weapons and launched spears of fire energized adamant towards the paralyzed half-demon. The spears impaled his body and exploded on contact, disintegrating and destroying Naraku completely, all that could be heard over the explosion was Naraku's horrendous dying scream. Naraku was dead at last, but the explosion had created massive winds that were sending everything in the area flying. Kouga soon felt something strike him painfully in the chest, that sent him flying towards the edge of the cliff.

"KOUGA!" Cried Inuyasha, he sprung after the wolf-demon to grab his wrist, but he was also struck in the chest by an unknown object and was also caught in the shockwave.

Both of them were sent flying off the cliff, each landed in a different spring below and both drowned in the process. When the shockwave of the blast died down their friends reached the edge of the cliff, just in time to watch their two fallen comrades die.

"INUYASHA! KOUGA!" Their cries echoed through out the valley.
