There is. It's the girl again, balancing in her sock-feet on the railing, looking like she could fall at any moment, too.

" - hey! Be careful!"

The girl leaps down, from three stories up, and lands, completely unharmed.

"Stupid. I'm already dead."

Kagome blinks.

"You're Mayu, aren't you? Satoru's sister? Why are you doing this?"

"I hate him, dummy! He should die! Mom only cares about him, and hates me! That's why she abandoned me to die in the fire!"

- she's such a normal-seeming mom, though. Mayu's spent more time around her than Kagome has, of course, but - she can't imagine - even a bad parent wouldn't leave their child in a burning building on purpose, right -

"I don't think that's true. I'm sure your mother tried to save you - "

"SHUT UP! You don't know anything! I'm going to kill Satoru, and if you get in the way, I'll kill you, too!"

She disappears again, with a flash, and then the entire sidewalk starts shaking. A whole line of flower bushes is ripped out of the ground and tossed into the air, followed by a tree, an old one twice as big around as Kagome is. They all fall to the ground with a horrible thudding noise, only a few feet away from her.

Wow okay this is in fact a demon level problem.

She holds Sota close, shielding him with her own body until the ground stops moving. The only thing that actually hits her is some clumps of loose dirt, but she can feel him shaking like a leaf. 

Then there's a sound. Not the sound of vegetation tearing. More like a flute. When she looks up - it isn't Mayu, looking down at them, it's some kind of - yellow spherical thing, with sleepy, half-closed eyes, and small arms that are just large enough to play the flute it's holding. It's some sort of demon; she's not sure what kind.

It flies off without attacking them.

" - come on, Sota. We're getting out of here."

Half an hour later, Kagome is heading through the well. This - whatever this is - is the sort of problem that she solves, but it's not the sort of problem that she solves alone.

"Inuyasha? You up there?"

He is, but it's not like he was waiting for her or anything, so it'll take a few moments for him to bound over to the well.

"Ready to go demon hunting?"

"I can't right now, something's come up!" She's already climbing the vines. The well by itself is going to make her so strong, for a fifteen-year-old human girl. She pokes her head out and pauses. " - you know a lot about demons, right?"

"Sure, why?" ... What's this?

"I saw one. On the other side. I don't know what it was doing, though. It's - yellow, and sort of spherical, with a tail like a feather, and two small arms. The rest of it's all face, and it plays a flute. It was following the ghost of a little girl around, playing music. I think she's a ghost, anyway. I was wondering if you would recognize it."

"Soul piper? You get those."

"What's a soul piper?"

"- They pipe to souls?" He doesn't actually have the faintest notion what deep spiritual role they serve or whatever but he's not going to admit to ignorance, that's WEAKNESS.

"I have no idea what that means."

Myoga is still around, and hops off of Inuyasha to perch on the edge of the well. "Soul pipers are gentle demons. They play music for the souls of dead children, and help them find peace, so that they can pass on to the afterlife."

"Oh. I guess that's good, then."

"...what happens if a soul isn't finding peace? If it's angry about dying, even months later?"

"Then the soul becomes an evil spirit. Whether the cause is regret or hatred, evil spirits that cause harm to the world are thrown into hell by the Soul Piper. You can tell whether it's about to happen by the eyes. When its eyes are closed, it's peaceful. When its eyes begin to open, however, it is preparing to drag an evil spirit into hell."

" - but that's awful! She's a little girl! There has to be some way to help her!"

"Pssh, don't bother. Ghosts aren't the sort of thing you fight. Can't take a sword to them at all, and you're risking a hell of a lot more than a limb or three going up against them."

"I can't just leave it. She's in danger! Her brother is in danger, too! And nobody else is going to help them, because apparently there's nobody else around who can talk to ghosts!"

"You can't do anything else."

"If the soul piper flies around trying to help souls find peace, then it's clearly possible to help them. Just because it's giving up on Mayu doesn't mean that we have to."
