She's led into the facility, then, and linked up with a blond man with a serious expression. He glances at her, then forms a single handsign - 

And the world jerks, and she's inside an enormous underground building. The walls are of stone, and water boils and rushes below. The man quickly goes to cling to the ceiling, and -

In the distance is a massive gate, hundreds of feet tall, a tiny fraying paper seal all that's holding it closed, and a massive demonic fox throwing himself against the metal bars. Naruto's crouched before the gate, clutching his head as the water swirls around him.

She rushes to the boy's side, places a hand on his back. "Naruto. Can you hear me?"

"He's so angry," Naruto says, eyes squeezed shut. "Just - anger and anger and anger - "

"It's all right. I'm here to protect you."

"- I think someone needs to help him too."

"I'm- not sure I can do that."

" - I - I think I can, but he's big and I think he wants to eat me and he's not gonna listen."

"I won't let him eat you. If you want to talk, I can try to hold him still."

"- Yeah, I think that'd be best."

"Okay."

With one hand, she conjures a shield, protecting her and the boy. With the other, she directs chains that slip through the bars of the gate to wrap around the fox's neck and limbs, dragging it down the ground and holding it still.

It turns into fire and reforms very angry about that.

The chains recapture it as soon as it has a body again. She sends a pulse of debilitating energy down them.

"I am as old as these mountains, mortal. Your tricks are nothing to me!" he roars, flashing forwards and slamming himself against the bars again. The paper tears a little bit. Still, he seems affected by the energy, even if only slightly.

"I've cracked mountains into pieces before." She puts a barrier in front of the gate and pulses the energy again.

He roars - in pain perhaps - and backs up, swinging his head side to side, snarling and glaring at her.

And then he opens his mouth, and strange black and white globes of energy begin to gather.

She sends another chain to wrap around his snout and keep his mouth shut.

The energy flicks to the confluence of his tails, growing enormous and unstable.

She assaults the energy directly, trying to disrupt it before it finishes forming.

The explosion from that doesn't seem to harm the Nine Tails much but does rattle the bars and tear the seal ever so slightly more.

She shocks the fox again.

"Just... stop."

"I will not take commands from the likes of you," the fox snarls, despite his mouth still being held shut.

"I won't let you hurt him."

He scoffs. "You humans are all the same."

"What do you mean by that?"

He just grunts, and breaks into fire again, reforming farther away from her. He swings his tails, slamming them into the water fast enough to break the sound barrier several times over - and sending a shockwave that vaporizes the water in its path at them.
