Rias had attempted to impress the seriousness of conflict with the church on Ryuko by explaining what it meant for a Devil to be Exorcised. However, even the threat of becoming nothing didn't sway her from the idea of such an intense battle. As she put it, "I haven't been sure of having a soul long enough to worry too much about losing it, and what's the fun of a big fight if the stakes aren't high?"

Thinking back on it, she rubbed her forehead as she focused on the now. The Archduke had sent them a message regarding a 'Stray Demon' on the loose in the town, which was her territory. As such, she was going to get to demonstrate to Ryuko what a battle was like for Devils, and the significance of the roles of the Evil Pieces and how they enhanced various abilities. In a surprising - though not entirely unexpected - turn of events, Satsuki was also in attendance to witness the capabilities of Devils, Stray or otherwise.

"You realize we won't be able to spare attention to keep you safe during the battle, yes?" she asked of Satsuki as they arrived at the deserted house where the 'Stray Demon' was known to hide out.

Satsuki turned and gave her a 'look'. Rias could feel the focused will gathered inside Satsuki's being. While not at the same power as an heir of one of the 72 Pillars, it would easily eclipse some of the weaker Queens she was aware of. If she was capable of exerting it beyond her own body, it would probably be enough for her to strike the 'Stray Demon' down on her own...and the wooden sword she carried with her suggested she knew exactly how to do so.

"...I meant no insult," Rias added carefully. "It is simply that you are in my territory, and my ally. As this is your first exposure to Devils in action, your safety and well being are my responsibility."

The 'look' faded and Satsuki nodded. "You have nothing to worry about," she assured her. "Now...do explain how these battles normally go."

Rias nodded in response. "Yuuto," she called calmly.

Nodding, Yuuto took up the narrative, explaining to Satsuki and Ryuko how a 'Stray Demon' was a Devil Servant who had betrayed and/or killed its former Master to live as it wanted. However, without the ability to make contracts, the only way a 'Stray Demon' could sustain itself without a driving ambition was to consume humans. As such, High Class Devils such as Rias took it upon themselves to police such Demons to protect humanity from them.

"So you clean up your messes," Satsuki deduced calmly. "That is good to know."

Rias flinched from the words at first, but quickly realized the 'you' in her statement referred to Devils as a whole, rather than Rias specifically. Nodding, she slowly pushed open the doors. "Tonight you'll see what undisciplined abuse of Demonic power causes..."

"She's here," Koneko stated calmly.

As everyone - except Satsuki and Ryuko - tensed up, a voice echoed from the darkness. "I smell something bad..." the voice purred. "At the same time, I smell something delicious..." On the last word, the voice took on almost ecstatic overtones. "Will it be sweet? Or will it be bitter?" On the last word, a figure partially revealed itself in the shadows, appearing to be a naked woman visible from the hips up with long black hair.

Ryuko raised an eyebrow, but said nothing.

Noticing this, Rias remained clinical. "Stray Demon type, Visor. They run away from their Master to fulfill their own desires. For their sins, they deserve death." She then focused her attention on the Stray Demon. "In the name of Duke Gremory, I'll kick your ass!"

Satsuki's gaze went flat as she gave Rias another 'look'.

"What an insolent girl!" the figure purred, raising upright as - for some reason - it began to fondle its breasts. "I'll cover you with blood as red as your hair!"

"Is this back and forth necessary?" Ryuko demanded dryly. "Or can we get to the fighting?"

With a laugh, the creature reared up...revealing a massive bestial lower body with huge, talon-like feet, a large blue gemstone where the human and monstrous portions met. As the laughter intensified, magic circles surrounded the figure's nipples as they became erect...and began firing lasers.

Rias and Koneko prepared to move to get Ryuko and Satsuki out of the way...only for Satsuki to calmly deflect the blasts with her sword while Ryuko batted them aside with her bare hands. "...did that even reach two star?" Ryuko asked Satsuki thoughtfully. "Felt like a one star hit to me, but I might just be tougher from turning Devil."

"No, about equivalent to the power of a One Star," Satsuki confirmed. "Perhaps a little stronger..." She glanced at where the deflected blasts had burned holes in the walls where they'd impacted, melting the material to slag. "Though that would prove problematic. Three or four One Stars with a Two Star in charge would be able to trounce this thing if that's all it's got besides brute force." She then turned to Rias. "You were going to demonstrate?"

Nodding, Rias turned to the others. "Yuuto!" She smiled proudly as Yuuto demonstrated the speed of a Knight, seemingly blurring out of vision as he dashed forward, cutting off the bestial arms of the creature with his sword.

Satsuki raised an eyebrow. "He wasn't really pushing himself...but I'd rate this showing about equivalent to Uzu taking it easy."

"Yeah, he doesn't need a Goku Uniform to go top speed anymore," Ryuko confirmed. "A sword fight between the two would be interesting to see."

The creature began to scream and writhe as Koneko approached...only for the chest of the beast portion to open into a mouth. With a shout of "Die!" it lunged, closing the jaws around the diminutive girl...only for her to force the jaws back open and punch the new jaw apart.

Satsuki rubbed her chin thoughtfully. "Seems she can take a hit as well as Gamagoori..." she murmured thoughtfully.

"He could hit harder than that with Scourge Regalia, though," Ryuko pointed out. "And he's gotten better since."

"Still a good sparring partner," Satsuki observed.

Rias raised her eyebrows as she heard this summation of her Perrage as compared to Satsuki's. If they were in any way accurate, then it was worth exploring to give everyone extra training.

Satsuki suddenly turned and let off a shout as she slammed the tip of her sword into the floor in front of her. A shockwave of pure willpower ripped past Rias close enough for her to feel the force...and eradicated the severed arm that had launched itself at Rias from behind, reducing it to a bloody smear against the opposite wall.

Rias stared in shock, turning from Satsuki to Ryuko to the smear. "T-thank you..." she managed to say finally, her senses showing her that despite the unleashed force, Satsuki's overall energy levels hadn't decreased it all.

"Never let your guard down on the field of battle," Satsuki stated calmly as Akeno began blasting the main body with demonic electricity. She stared at the beast for a time, then turned to Rias. "I would like to let Ryuko deliver the finishing blow, if we may."

Rias blinked in surprise, but nodded. It would be nice to see what Ryuko could do.

Turning, Satsuki turned and tossed her sword to Ryuko, who caught it as she charged the beast. It turned towards her...and she delivered what looked like a wide swing as she passed through it. The tableau held for a moment...and then with a scream the beast exploded into threads of energy before dissipating, the most solid of the threads instead being drawn to Ryuko before being absorbed into the red streak in her hair as it glowed, the glow fading once the power was claimed. Rias' eyes widened as the black mist of her own Destruction Energy leapt out in wisps from Ryuko, scouring the building of every trace of the beast's body and power as though consuming it before returning to her.

"W...wha...?" Rias asked in shock as Ryuko tossed the sword back. She wasn't the only one left flabbergasted.

"When the conflict was purely Life Fiber based, Ryuko could absorb the Life Fiber energy of those she defeated," Satsuki explained calmly. "It appears this carries over into fights with the demonic now that she's part Devil." She rubbed her chin thoughtfully. "Though none of the prior defeats were lethal..."

"No clothes, sis," Ryuko pointed out. "Pretty sure if I struck the way I did against Goku Uniforms on Devils, it'd leech the power out that way without killing them."

"Best to test it on someone else's Evil Piece, though," Satsuki allowed calmly. "Perhaps one belonging to the asshole Uzu deduced?"

Ryuko grinned widely. "That ought to be fun..." she purred excitedly. "Though...maybe I should retrieve those blades if fights like that will happen."

Rias decided mentally that unless it came up, she did not want to know.
