The plan

"True but with my current powers I can only act after the other personalities make their appearance: So that means, I'll have to stick even closer to you." Enira was busy rubbing her body against mine. I gave her a nice punch on her head, between the horns: hard! "Ahem! Precisely, so we won't need Hyora to be alive for sealing purposes." She sniffed, let out a tear but kept a straight face.

Just what the hell was wrong with the dragon-snake thingy?

"You realize, we're talking about how to kill her right? We aren't talking about why we're killing her, but how!" Elsa grumbled. 

"Right, right." Enira snickered. "We'll trap her in a barrier, and kill her by burning her whole body to cinders. We won't leave a single cell. Should be enough to kill even a primal vampire."
