"You heard me." Yuka replies.
Something tells you that you shouldn't be hearing this. Conversations held in the dead of night are the most closely guarded secrets, not for the ears of those who should be asleep, who are tucked away in their own little dream worlds, safe and secure from the horrible knowledge spilling fourth.
But you can't help yourself. Ran's a ... friend? Ally, at the very least. Yuka is scary, like a force of nature given form, but she's not tired to hurt you. This is-
"What 'favour' could you possibly have done me?" Ran says, the chill of her voice shocking you again.
That's what you're listening here. What's going on, what's happened?
"You damn near traumatised her!" Ran says, sounding more animated now.
"And how would you know that?" Yuka asks.
"The kitsune told me everything that happened, including your refusal to protect their siblings from the Fujiwara girl."
"They ... fucking dogs." Yuka says, you hear her heavy footsteps and for one horrible second your insides freeze. Is she coming towards the door? Your heart leaps into your throat and you bunch your robe up in your hands. Run ... stand here? You-
Breathe out a slow puff of tension as Yuka's footsteps recede in the other direction instead. Sounds like she's pacing up and down.

"You let seven of them die." Ran says. "I sent them with you for a purpose."
"Who cares? They're animals."
There is a growl, a sound that activates something so basic and primal that you can't ignore it, especially in a dark corridor at night. A long, low, canine growl that makes you think of bared teeth and unsheathed claws. So loud that it must come from an animal big enough to swallow you whole. Your palms sweat and your bowels tighten, instinct on the verge of taking over.
"You want to fight me?" Yuka asks, laughing. "Oh Ran, once this is over you get pride of place, first try, if you want. I could never turn you down."
That growling noise was Ran?

There is silence for a long time.
"Very well." That's Ran again, but she sounds even more exhausted than before, a hoarseness to her voice that wasn't there before. "What is this favour you believe you have done me? Rid me of some of my charges? Psychologically scarred that poor girl? Angered me? What?"
Yuka laughs again. You wish she would stop laughing at Ran.
"I showed her violence." Yuka says. "Nobody understands violence like I do."
"And?" Ran demands. "What purpose did that serve? Why? We could have questioned that man, damn you!" Something slams into the floor, probably Ran's fist.
Another long silence.
"You don't get it." Yuka says. "You can do it in the back-rooms, away from her. You can be her proxy, so her hands are never bloodied-"
"Don't say it."
"You can hide it from her, pretend she doesn't know-"
"Shut up."
"She must know violence, Ran." Yuka says. "Yukari knew violence."
"She is not Yukari!" Ran roars at Yuka. The sound makes you shake a little.

Yuka laughs again, clashing with the weight of her previous words. The sound of her laughter makes you picture her clutching her sides, rolling around on the floor.
"Get out." Ran says.
"Out? Or outside out?" Yuka says through the laugher.
"Just get out!" Ran shouts.

You hear Yuka tut, her footsteps drawing close to the door again.

[ ] Slink away before she emerges, you don't want to see either of them, head back to your room.
[ ] Stay where you are, frozen with the shock. You can't move, you can't think.
[ ] Head back a little way, wait for Yuka in the corridor. You have to know what she meant.
[ ] Hide from Yuka, you need to see Ran. She's angry, but she cares.
