And there's a snapsnapsnap as the puppet-strings around her left hand fall, severed, and she's off-balance for a moment and falling - 

But a flick of her comb and the strands wrap around it and she can pull herself back up to safety, new strings ready to use and connected to the web.

"Not very gentlemanly of you, but I suppose I can't expect more from a dog."

- great, okay, she can just reconnect herself to the web at any time.

"She has new strings now!" she yells up to Inuyasha, on the general principle that observing things doesn't help if Inuyasha can't do anything with it. She realizes halfway through that the amount of blood from that wound looks bad.

"Let me show you how this dog bites!" he yells back at Yura, ignoring Kagome's words on the grounds that (so far as he is concerned) they're really obvious.

And he digs his hand into his own wound and it comes out red, and - 

"BLADES OF BLOOD!"

Yura is now short one (1) hand!

Also one (1) magic wakizashi!

She seems kind of shocked by these facts!

This shock does not stop her from collecting the hand-holding-a-sword with her strings and going for some more Inuyasha Stabbing Time, since he's still kind of stuck in midair incapable of effectively maneuvering.

(Though Kagome can see that none of the strings from her body are directly puppeting the sword, so much as they are connected to strings that connect to strings that... puppet the sword.)

(Meanwhile, in Banter: 

"Really, is that anyway to treat a lady?")

("Fine way to treat an ogre!")

In the space of about a second, Kagome's brain produces two parallel thought processes. The first notices that Yura can puppet her own severed hand. Except that - it doesn't look like Yura is puppetting the hand? She'd have to be doing it with her other hand, right, and something about the movements there isn't adding up - the hand is being pulled by strings, but not by strings that Yura is visibly pulling.

The other thought process is characterized by immediate wordless panic about the sword that is now hurtling towards Inuyasha, who is mostly pinned, and getting more pinned all the time. An opportunistic hit was bad enough; a direct hit might kill him. This process brooks no hesitation, and will hear no objections, not while the careful part of her mind is focused on the hair. She has a bow. She may not have any idea how to use the bow, but if something is going to be done about the sword - and there is no one else to do something - then there's no time for doubting herself. She pulls an arrow out and aims at Yura, and then lets the arrow fly.

...it misses, of course, and instead hits the giant sphere of hair behind her.

Empowered by holy light, the arrow splits the sphere open, causing HUNDREDS UPON HUNDREDS of skinless, fleshless skulls all connected by their still-living hair to come spilling out!

... And Yura to stop her sword's advance and turn furiously towards Kagome, raising her comb in wrath. "I'll burn you to your bone marrow!"

And fire shoots out from her comb, burning along the strands of the great mass of hair she hurls, flooding over her and her surroundings in a vast wave, a typhoon of flames to wash over her and consume her until nothing is left but ashes.

Kagome drops to her knees and cries out, instinctively covering her face and hands as much as possible, which happens to mean mostly hiding them in the red robe she's still wearing.

... Over which the flames wash harmlessly.

As far as anyone else can see, though, Kagome's just been consumed; the red lump is hidden beneath dancing flames that conceal what, exactly, just happened.

"BLADES OF BLOOD! BLADES OF BLOOD! BLADES OF BLOOD!"

(He really is digging into his own injury for ammunition at a surprisingly unsustainable rate!)

And Yura is dodging like mad and picking up quite a lot of wounds that look like they probably ought to kill a normal person, though who knows how resilient oni are.

Doesn't seem to be stopping her, though.

It takes a second, but not much longer, for Kagome to realize that she mostly isn't burning; she can feel the heat, but the vast majority of it is being stopped by the robe. She crawls, very carefully, huddled under the robe like a turtle in its shell, until the heat seems to lessen and she feels safe peeking out. She watches Yura and Inuyasha, locked in combat, and swallows a lump in her throat at the sight of so much blood.

She watches how the hair moves, how it pulls, and how Yura seems to be able to shrug off pain and damage in a way that Inuyasha and the centipede and the crow were not, and she gets it: the Yura they can see isn't the puppet master at all. Yura is a puppet. The puppet master is... inside the nest of hair, obviously, a puppet master has no need to leave the safety of their lair when their puppets can do it for them. Whatever the source is - whatever the real point that will sever all the strands if cut - it has to be inside the nest.

The still-suspended, razor-sharp, skull-filled, giant nest of dead people's hair.

That only she can see or reach.

Okay. She can do this. She crawls up to the dangling mass of hair and skulls that have spilled out onto the ground, tries to shield her hands in the robe as much as possible, and starts trying to climb.

Yura is too busy to notice her! Yura is trying to not get cut into tiny little pieces, a policy that is not going that well!

New plan: Swarm Inuyasha with VAST NUMBERS OF HUNGRY SKULLS - 

"Don't waste my time!"

- Try to stab him in the chest with the puppeted sword while he's distracted -

Yeah, like that's going to work!

"Almost got your head."

- Then actually stab him in the back once he thinks he's deflected the attack.

That one hurt.

"Not... down... yet..."

But between blood loss (some of it self-inflicted) and the more direct harm from having holes poked in bits of you that you actually need, Inuyasha is having trouble standing, and is, in fact, mostly hanging from Yura's web.

Well, fight's over, might as well collect Inuyasha's head. He has such beautiful hair, shame to get it bloodstained.

Yura descends to near Inuyasha's level, surveys her right wrist (she'll need to sew it back on, later...) and takes her sword in a left-handed stance, ready to take his head off with the minimum mess.

And that is when he rips out her heart.

And the Shikon Jewel shards she kept near it, of course, just in case they were the explanation of her healing abilities.

"Now, witch, do you see why -"
