Orion sat on the dresser as Rias placed her dead counterpart in the middle of the room and started undressing her.
"Ask away, Orion. I have an offer for you after you are done with your questions."
"Let's start with the elephant in the room. Why did you kill your…copy?"
"Alternate self," she corrected him. "And I did so because the longer she lived, the weaker I would get. I would get entangled with her and lose what paltry powers I have access to and completely turn into a weak girl with no supernatural means to speak of," she said. "That's what happens when a person hops between realities. Two multiversal variants of the same person cannot exist in the same plane of existence without special circumstances."
"So is that why the magic circle didn't work, and your magical power is suppressed?"
"Precisely. I am not keyed into the Gremory circles in this reality, but there is a faint match, which caused the circle to appear, but it fizzled out soon after. If I didn't kill her quickly, my energy would continue being suppressed until nothing was left. Even now, I will need at least a few months to return to my peak state."
"Was that thing about Ophis you said true?"
"Yes and no," Rias said. "This reality will be invaded in a few days, yes. But not by Ophis. By another reality. The multiverse is collapsing, causing countless alternate versions of our worlds to clash into each other. The clashing realities will attempt to impose their authority on each other and suppress almost all denizens within them. That leaves the Primordials. Ophis and Great Red. Some realities clash and destroy everything, but some try to resist and end up getting devoured, and some escape to the Outside."
"This is… a lot to take in."
"It is what it is, I'm used to it," she said, finally standing up after undressing her dead counterpart and making sure she was lying straight with her arms by her sides.
"So what do you plan to do after killing her?"
"I've been looking for a Multiverse Independency," she said. "Something that is not affected by the authorities of realities when they clash, or when I shift between them."
"Does something like that exist?"
"It does. If it doesn't, I'll make it…" she said. "My reality was destroyed five years ago. I keep escaping to different realities in hopes of finding something that might work."
"Five years?" Orion widened his eyes. "Aren't you supposed to be the sister of Lucifer? Why is your max energy capacity so low, even after so long?"
"I don't recall telling you about my level of strength," she said, looking at him with narrow eyes.
"How sharp," he said. "I can sense your magic power. We are already bonded, after all."
"You know what I want, what about you. What do you want?" She asked.
"You didn't tell me what you wanted; you merely told me about the means. I want to know what the end of what you want is."
"I want to kill someone," she said. "Your turn."
"I don't really know. I'm more of a drift through life kinda guy, you know? Maybe I'll ask you out on a date or two, and we could slowly grow closer. I wasn't exactly expecting a multiversal threat to fall on my head out of nowhere."
"That's what happens," she nodded. "As for your date plan. I don't mind agreeing, but let's postpone it until we can confirm how long this reality will survive; however, don't expect me to casually have sex with you. Unless I know you're sticking along long term, I won't allow anything of the sort."
"Oh, I'm sticking around all right," he said. "What did you need me to do?"
"I will share an image with you and need you to create it using your body around her. Think you can do that?"
"Do you want to use me as a conduit for your magic?"
"Using your sword, I realized that your body is a very good conduit for magical energies," she said. "Are you willing?"
Orion stood up and approached her, stopping barely arm's length away from her. "How about a kiss in return for my efforts? I did help you kill her, after all."
"Didn't I say nothing sexual?"
"You said no sex," he iterated. "There's a difference."
"Are you sure that you wish to make our relationship transactional?" She asked, showing a smirk. "Won't you have a lot more freedom and leeway if we keep things less transactional?"
"Damnit, I thought I'd get to make out with a hot redhead that I just met. Pity. Tell me what you need."
Rias telepathically shared the image of a complex magic circle with him, which he quickly copied onto the floor, treating her dead counterpart as the core of the circle. He wasn't particularly proficient with magic circles and required some corrections from Rias' side, but they were finished within a few minutes.
"All right, you can get started," Orion said, crossing his arms as he saw Rias sit cross-legged above the head of her dead counterpart. She didn't seem the least bit bothered by the lack of her clothes in front of him, to the point that he felt a little frustrated. He wanted to see her at least a little flustered or even affected by her nudity, but she seemed downright stoic.
Through the connection, he could feel Rias channeling almost all of her remaining three hundred or so units of magic power before she poured it all into the magic circle that had been created by his own body.
As he reveled in the sensation of magical energy coursing through him, a loud moan caught his attention, and he looked at Rias. Her body was arched, with her head thrown back as she used her hands to stay upright while pushing her tits forward as they rose and fell with her deep breaths. As the circle continued growing, she started trembling, and he felt the connection he held with her grow a little stronger.
An electrifying sensation suddenly shot through him, forcing a pained groan through his mouth. Before he could call upon his status, the system's words appeared in his vision.

The last line was what ended up with Orion losing his physical form and falling into a puddle of slime. The last thing he saw before falling unconscious was the magic circle composed of his body coming alive and enveloping both the alive and the dead Rias, along with him.
…
When Orion regained consciousness, he noticed that Rias was still unconscious, so he separated and formed his own body. Immediately, he realized that the dead Rias was gone, leaving only him and the Rias he'd come here with. She was still unconscious, curled up on the cold floor in an uncomfortable-looking posture. He leaned forward and picked her up in his arms to place her down on the bed.
"Damn, she's beautiful… I wonder what she will think when she realizes the kind of freaky things I'm into?" He chuckled before turning his eyes to his status.

Tantric, huh… The system really gave me a verse-appropriate ability. Specialized powers that are completely based on sexual interactions in a world focused on tits. Can't wait to test it out once she wakes up…
Orion didn't have to wait for long since Rias woke up barely a minute after him, groaning and stretching her arms lazily in a way that made it extremely difficult for Orion to hold himself back.
I swear, if she keeps acting like this…
"What happened?" She asked him with a frown, immediately sitting up.
"We didn't account for the spell reacting to me and adding me into the mix. Even though I'm not sure what exactly happened, I can sense that your maximum capacity of magic power has increased a little, along with your physical stats. Though they are still pretty low."
"I can now sense your presence…" She said, placing her palm on her chest.
"That's because the spell also caused us to increase our sync state," he said. "As a symbiotic species, the closer I am to my host and the greater the syncing percentage between us, the stronger both of us get."
"Whatever happened with your intervention significantly enhanced the spell. This time, I even got her memories. I've only ever gotten snippets before," she said. "I have to go meet Akeno soon. We should leave as soon as I recover some of my energy."
"About that," Orion said. "I have a way to speed up the process."
"You should've said that before," she smiled, looking impressed as she sat up. "Go for it."
Orion nodded, and his hand immediately reached out to cup one of Rias' heavenly breasts.
"Hey!" She exclaimed and immediately jumped back before he could touch her chest. "What are you doing? Keep the perversion to your eyes. No touching."
"I thought you wouldn't care," he said. "To help you recover, I need to sexually stimulate you. The most tame way is through your breasts."
"Do you have incubus powers? Those things are supposed to be extinct throughout our multiverse."
"Are you shy, Rias?" Orion asked, unable to stop the smile that broke out on his face. "Have you never been touched by another man?"
"What the hell are you talking about? I had a lover in my original world. Granted, I used illusions, but I cared for him."
"So he never touched you?" Orion quickly caught on, and she looked away, unable to meet his eyes.
"I don't need this kind of sexual recovery," Rias quickly regained her composure and refused. "I'll just wait to recover naturally. Keep your slimy tentacles to yourself."
"Tentacles?" Orion asked, confused. "When did I show you tentacles?"
