Her opponent seems alarmed!

She dodges, stomping her feet and causing a ripple of earth to surge around Chihiro.

She plants the tip of the sword in the floor and jumps up, using the hilt to brace a sideways kick.

She rolls with it - and a burst of grass surges around Chihiro from where she struck the girl, whipping around her limbs.

She pulls back, does a handstand on the base of the blade and rotates back around to a standing postion, passing her legs over the edge and slicing the bindings loose.

"Oh come on - " the girl mutters.

Another stomp, and the stone turns to mud, the sword sinking into it with a sucking noise.

A touch of chakra and her sword cuts its way free easily enough. And if she channels chakra to her feet, she can walk over the muck as well, using the same principle as waterwalking. Her enemy's gambit thus nullified, she again attacks, a low disabling slice to the legs.

Her opponent jumps, and there's a soft  swooshing rustle from behind Chihiro.

She follows through on the slice and carries it around, aiming up to intercept whatever's behind her.

Grass whips that explode when cut, with more force than before.

She's knocked back, attempts to roll with it- A sharp spike of pain means this was a bad idea, but she still has a grip on her weapon and her enemy is not yet neutralized. The rest can wait.

There's a soft ripple in the ground under her.

She's already moving, pressing the offensive. She preferentially dodges the grass constructs, and uses the far end of her sword to attack those she can't.

It turns out they're fully capable of exploding prematurely if they get close enough to her.

But the crowd is thinning a bit over time.

She's getting better at dealing with the explosions. She gets in close again and engages the Grass ninja with her sword.

The girl seems to utterly lack acceptable mid-range melee options, and is mostly reduced to dodging, which she isn't perfect at -

Accept instead of blood she seems to bleed grass.

That seems wrong. A construct, perhaps?

The next time Chihiro sees a opening for a potentially fatal blow, she takes it instead of letting it pass by.

The girl bursts into grass, which lashes for Chihiro, several strands crackling like they're about to explode.

She dodges backwards, clipping off the ones that get too close for comfort and then dodge back more, because explosions.

Meanwhile she reviews the fight so far for places where the girl could have switched.

There were several times her line of sight was blocked, especially early when being swarmed.

There's another very faint ripple under her feet.

She'll have to be better about that sort of vigilance, especially so soon after the puppeteer's fight.

She slashes the floor again and uses the sword as a stand.

A pause, and then the girl emerges as far from Chihiro as she can, her hands up.

"I surrender," she says. "I'm out of chakra and constructs."

The proctor calls the match over, and Chihiro sheathes her sword and heads back up.

"You did really well, Chihiro!" Naruto says, bouncing. "Also we all passed now!"

"There were aspects I could improve upon," she says.

"Yeah, me and Sasuke, too. That's what training's for."
