Penny had been afraid she would say that, of course it was true if she lost, she would lose a great deal of her power and dramatically cut her life span down, but the little demoness wasn't exactly fond of sitting around and doing nothing. In the end, she was a Demon Overlord once, and she had pride to uphold,
"Oh come on now," Penny grinned, "I still have more battle experience than everyone here, I know when I'm licked, but I've beaten tougher opponents than myself with my smarts as much as I have with my power." She replied confidently, thumping at her chest as she did so.

"But you know, it's not the end of the world if I die." The childlike creature smiled at Emma, "If it happens, don't blame yourself, there's certainly some-one at fault for my situation, but it's kinda hard to blame them," the girl chuckled. She was referring to Overlord Varnus, of course, the whom had destroyed the pathways between worlds in the first place, but if anything it seemed to be in jest.
The alternative could have been far worse, Emma may not even have existed at all, perhaps not even Hannah. Thinking on it now, those were things Penny certainly didn't want now, having met with these two. Life with them had been great. And, in spite of what was happening, it still was.

"I can say this much, I don't know if it's a good idea or not to start reopening mana pathways. It could cause complete chaos. But it's also a doorway to unlimited adventure for those who are strong enough. And the most important thing to remember is that there is always some-one stronger. Hadrien is a small fry. At my full power; he wouldn't even have been much more than a mild nuisance nipping at my ankles. But right now he's towering above us all. No matter what happens; sooner or later you're going to have to beat him. How you do it and what you do to him will be up to you, though." Penny advised, standing up and stretching.

Hannah stood tall as well, staring down at Penny a moment, but then turning her gaze towards Emma, her arms folded. The woman seemed to be in heavy contemplation, in fact, she had been since Penny mentioned her coming up with techniques. In much the same way as day to day magic that cost the smaller reservoir of refillable mana, even close-range brawlers like Hannah could use that reservoir of power to increase the potential of their attacks, often adding special effects to the attack or increased power or speed to those attacks.
For this reason mana was often referred to as the Energy of Dreams, for one with enough Mana power could be said to rule the cosmos if they were strong enough. A far cry from Hannah's own desires, , but certainly the priority of demons like Hadrien.

Peny seemed to perk up curiously, as if she could hear something, of course it would soon be felt by Hannah and Emma,
"Oooh, that's Slayzer's energy, I wonder what he's doing?" She grinned broadly, after all, his power could be felt rising as before, the same feeling spread through the ruins. He was definitely strong, but he hadn't pledged to help them fight, in fact he'd never said such a thing, even though he'd helped so far, Penny wondered about it,
"I wonder if he'll actually join in the fighting.. It's not like you can physically command him.. Eh-ha! Who am I kidding? He'll either sit there and do nothing, or he'll get so antsy to test his strength out on real opponents that he'll join in just because it looked fun at the time! Y'know he's actually a lot like me when I was that young.." After saying this, of course, Penny pulled a miserable face, "Oh poo! I feel so old again...!"
