I don't own Naruto or the Marvel Universe.
Tsunade stared at her former teammate “What do you mean you lost him?” She asked Jiraiya.
Jiraiya scratched the back of his neck. “Well, we were near the border of Rock Country and I went into a small village to get some supplies.” Jiraiya started..
“You mean you went into town to look for some liquor and a willing prostitute.” Tsunade said with a frown.
“Well...yeah.” Jiraiya admitted. “I've needs you know. When I got back there was note that said he needed to go do something and that he'd be back when he could.”
Tsunade rubbed her temples, soothing the headache that was already forming. “Right, exactly how far had you gotten in training him?”
“Well, his chakra control is crap as always, it will be as long as he has the Kyuubi in him. He regenerates more chakra than he uses and he wastes enough for C rank techniques just by breathing most of the time. He's beyond Kage level in Chakra levels, but he wastes too damn much in everything. He's been learning what I teach him, but it's all mostly high class stuff since he has problems with the smaller things.” He told his old teammate.
Tsunade nodded. “And how far has he gotten in using the fox's power?”
“Five tails without losing control. Though I don't know how much that would be if he didn't waste so much. That's just what forms, what's wasted, well I can't tell you.” Jiraiya sighed.
“And you have no idea why he'd willingly walk into Rock country?” Tsunade asked him.
“No, and that's a problem. He doesn't know who his parents are. If they find out he's the son of Minato, well I don't know what they'd do but it sure as hell won't be pretty.” the Toad sage said with a frown.
“Well, I want you to slip out of the village undetected. We can't let the council know that he's gone missing. They'll have him in the Bingo book faster than either of us can say 'sake'.” Tsunade said.
Jiraiya nodded. “I'll do what I can in finding him before Akatsuki does.” He said before leaving via the window.
Tsunade stared out the window. “Naruto....why?” she said aloud.
Elsewhere... in Rock Country
/Stop here Kit./ came the Kyuubi's voice in Naruto's mind.
“This the place?” Naruto wondered aloud.
/It is, now use my chakra for the Jutsu./ The Kyubbi demanded.
Naruto nodded. He formed the handseals and his body was enveloped in red chakra as he slowly began to sink down into the rocky ground he was standing on.
/DEEPER! GO DEEPER!/ The demon fox commanded as he sent even more chakra for his container to use.
Naruto began descending deeper into the earth at a much faster pace, he was phasing through solid stone as he poured demonic energy into an earth technique he'd once seen his former teacher use.
Suddenly they reached an area and Naruto fell as he canceled the jutsu. He flipped and regained his center of gravity and pumped chakra into his legs to cushion his landing.
/THIS IS IT/ the fox told him.
“I can't see anything.” Naruto said as he sniffed the air. “It's stale as hell in here.”
/THIS PLACE HAS BEEN SEALED AWAY FOR A LONG TIME/ the fox said as it directed Charka to his container's eyes.
Naruto blinked as the area came into focus in black and white.
“Where are we?” he asked the fox.
/A PLACE OF A POWER OLDER THAN MYSELF, THE LAST TEMPLE OF CYTTORAK. NOW GO TO THE TEMPLE, WE NEED TO HURRY. THERE ISN'T A LOT OF USEABLE AIR HERE./ the Fox told him.
Naruto nodded and leapt towards the temple. He needed to get to what the fox had sent him here for. A solution to both of their problems.
“Is this it?” Naruto asked as he made his way to the interior of the temple and saw the large gem on a dias.
/YES, A POWER OLDER THAN THAT OF THE BIJUU AND THE SHINIGAMI, ONE AS OLD AS WHAT WE ONCE WERE, THE CRIMSON GEM OF CYTTORAK. USE IT KIT. PRESS IT TO THE SEAL AND SAY WHAT I TOLD YOU/ the fox demanded.
Nartuo removed his shirt and pressed the gem to the seal and recited the words he'd learned. “Whosoever touches this gem shall be granted the power of the Crimson Bands of Cyttorak! Henceforth, you who read these words, shall become ... forevermore ... a human juggernaut!"
As he spoke these words the gem and the seal glowed. The fox had told him it would hurt, but this was unbelievably painful. Naruto felt something pass through him before he passed out from the pain.
