She wasn't leaving. Ruli accepted that, turning his attention back on Akuma. He ducked and grabbed, pulled and retreated, trying to expose more of her skin, trying to find a way to get at her once more. To rip into her mind and bring her to her knees, or to take his teeth to her flesh and tear her apart.
He hoped for the former option, as the taste of her blood was worse than anything he'd ever tasted. 

But just as he went to assault her again, and she raised her sword to meet him, they all reeled, the dolls collapsing in the chamber. The noises they made echoed in his ears. And he beheld Akuma's gaze and the light in them that increased as her power increased. Ruli swallowed. Ysaryn was still swinging, taking down the ones by the entrance that hadn't fallen yet, so Ruli kept his waning focus on Akuma. On his fight. 

Then Kire came. Ruli had attempted a last attempt, doing nothing but making AKuma turn as she dodged him, listening to his ragged breathing. He was nearer to the entrance, to Kire, Ysaryn, and ... the half-breed, apparently. She shouted orders, and while Ysaryn stayed, the taller figure turned to listen, disappearing into the darkness. 
Ysaryn, however, whirled around to look for Ruli as Kire, too, ordered him out. He didn't listen. When Kire lunged, so did he, and Ysaryn threw herself between him and the women. He shoved her aside easily, growling like an animal, before he and Kire backed Akuma into a corner. Not knowing what to do, Ysaryn flanked them, swords ready, eyes wide. 

As Akuma raised her sword, Ruli tensed, flexing his legs to prepare to leap at her, only to falter in surprise when she raised it to her own throat instead. "Wh-" Ruli began to ask. He wanted to watch. Wanted to see her die. But when Akuma opened her neck and the caverns seemed to react to it, he decided against it all. He looked up, wary, unsure. 

So they ran. Ruli and Ysaryn, both tired and bleeding, the former's stimulant on its last legs, lagged behind Kire. When he heard her laboured breaths, Ruli reached out and grasped Ysaryn's wrist, meeting her gaze for a second. Long enough to promise he wouldn't let her fall behind. 
"I can ... get us ... out!" He shouted up the tunnel. His mind was clear enough now to Walk without endangerment.
"No!" Ysaryn snarled back at him. "Others!"
[i]Dammit.[/i] Ruli understood then, and raced on.
