Kidnapped!
1st Boss: Mist Heir

"Summoning Jutsu! Divine Gate, Cave, Northwest."

A large stone door shot straight out of the ground with a rumble. The great door opened, and in it was the blocked cave shown by Eye #1.

"Well, what're we waiting for? Let's go!" said Naruto.

Naruto jumped straight into the door, while Kiba and Kenshin walked in after him.

Kiba felt like he had walked into a wall of ice, it felt like he was dead already.

"Hey, Kenshin! Come on!" yelled Naruto.

Kiba nosed the air around him, as did Akamaru.

"Yep, their scents are real clear round here."

Kenshin only smiled under his mask.

"Getting in won't be that easy and if my guess is correct, we'll have company…"

Inside.

"Three of them, all male, one of them is rubbish, but the other two are phenomenally strong, both have loads of chakra reserves, and one seems to be the one we're waiting for…"

Sasuke only nodded.

"But-"

"But what?" said Sasuke.

"The other one…I don't know…his chakra is…differe-."

And with that, Karin suddenly stopped dead in her tracks.

"The other one, he knows I can see him."

Sasuke looked straight into the large boulder blocking the cave mouth. He looked back to Karin, and saw that there was a small trickle of blood under her left nostril.

She suddenly collapsed, her limp form on the cold cave floor.

"Well…since Jugo's all calm and shit, looks like I'll be the one to do the fighting…" said a figure to Sasuke's left.

He stood up; screwed in the handle his blade, performed the handseals, and melted instantly into the floor.

Now all alone, Sasuke found himself questioning why he took the order to guard the prisoners.

With Madara, you don't have much of a choice… he mused.

Outside.

"She's out."

"What're you talking about?" asked Naruto.

He turned to Naruto, and saw that the eye slits for Kenshin's mask, usually covered by a light blue windscreen, was open, and saw that Kenshin's eyes were a shade of gold, where his pupil should be, was a kekkei genkai, in the shape of a black typhoon.

It reminded him of the Sharingan.

"What the-"

Immediately after Naruto said that, the blue screen lowered and covered his eyes once more.

"Uh, sorry you had to see that, I just had a strange feeling…"

He looked back to the massive boulder again.

"-That someone was watching us…"

Naruto looked at Kenshin with squinted eyes, then back at the large rock, then he simply shrugged and looked for something to do while waiting.

"Hey, so what're we going to do about the seals?" asked Kiba.

Kenshin pulled out the letter from his pocket, and was shocked that it had changed.

It now said….

Rem,

You face the First Boss, Mist Heir.

Again, chill.

Round 1…

Fight!

"What the…"

Then a voice rang out from his right…

"HEY GUYS! I FOUND SOME WATER HERE!"

Kiba immediately rushed over to Naruto, invigorated by the prospect of drinking cool, clear water.

Kenshin pondered on the letter's words, and then, he flipped it over…

His eyes lit up with sudden realization as he saw what was written on the back of the letter.

"KIBA! NARUTO! NO, DON'T!!!"

Almost as if on cue, Kiba burst out of the forest like a living missile, rocketing straight into a tree, propelled by water.

The water suddenly took form, and took on a human shape. And from it stepped a figure, wielding a massive sword.

"My name is Suigetsu Houzuki, the Heir of The Mist Swordsmen!" he said as he brandished his massive sword, Decapitating Carving Knife, using his Great Water Arm Jutsu to wield better.

He took a swing at Kenshin, aiming for his head…
