"...Huh?"
"Huh?"
"Whaaaaa…?!"
"...Lord Rimuru?"
"...Lord Rimuru?"
Isis, am I dreaming? Wait, do I dream? NO, I DON'T! What;s going on here, and how is it that I'm only realizing this now?!
'Report. In order to ensure master has a good sleep, Horus's 'Dominate Soul' subskill was utilized at Risa's request, in order to force Master's soul into a mode of 'True Sleep'. Dream memories have been banished to the recesses of Mnemosyne and sealed. Would you like to revisit them?' Isis explained to me.
"...What?" I asked aloud, shocked.
So, it went like this. Last night, I was in my little 'sleep mode', a meditation technique I'd developed in order to simulate sleep. Meanwhile, Risa had been thinking with Thoth.
And she'd realized something pretty important. Horus could basically do anything, so long as it had enough power, or at least the right permission. It had its limits, but anything that had to do with 'modification' was basically free game. The definition of 'modification' was the only real limit, aside from the raw power required.
Horus's abilities even included forcing someone who normally didn't sleep to sleep. And since I was already trying to sleep, Isis didn't even really need to think to ask before helping me, putting my consciousness out like a light while it stayed awake, watching over me while my soul dreamt.
Now, that was fine. Incredible, even. I'd officially regained all of the minor bodily functions that I'd lost upon reincarnating into this slime body of mine. I could taste, sleep, and even reproduce now. It'd just required Demon Lordification!
The real problem was what'd happened afterward. As an apology for shoving this onto me, Risa gave me access to the files of her thought memories during the incident.
Not that I actually understood much of it, since she was using Thoth at the time. But I got the gist.
Basically, Risa'd been lying in bed, bored, thinking of ways to alleviate her boredom. Then, she'd suddenly started wondering if, with her new abilities, she could sleep.
So, she'd developed a method of sleep. But she hadn't stopped there. Eventually, her mind had gone straight to the same place that ir kept getting stuck at.
Milim. From there, it'd gone to the idea of companionship. In an amorous sense. And the fact that I didn't have some other half like her and Milim.
My headache raged in my nonexistent brain once again as I relived Risa's irritating logic. Apparently, since I didn't have someone who I could share everything with like she did Milim, Risa decided that drastic action needed to be taken, while I was still asleep.
So, she replaced my room with Shuna's.
Yeah, she'd basically used Dominate Space to swap the interior of our houses, which ended with Shuna and I waking up in the exact same bed, her in her cute pajamas that I'd never seen before.
Now, Shuna and I were both mature, responsible adults. If that'd been the end of the story, right then and there, I'm sure we could've simply laughed it off and continued on as if nothing had even happened, maybe just a bit of awkwardness.
…But…
"Shioon! I wanna hug him, too!" Yeah, I'd woken up sandwiched between a scantily-clad Shion's breasts. And, apparently thinking that it was some sort of strange dream, Shuna had instantly grabbed onto me and pressed her own chest against me, leaving me, a very confused little slime, sandwiched between four breasts.
Then, the two oni girls simply fell back asleep. With me still sandwiched between them.
Now, this had happened before, but they'd always been awake, and fighting over me with those really scary twin smiles on their faces as they did so. This was… different. Far more intimate.
Isis, can you put me back to sleep for a little while longer?
…
I ended up sleeping between Shuna and Shion for the next half-hour or so, before they finally both woke up and realized that no, they weren't dreaming.
The result was immediate and powerful. Almost instantly, both girls were on their knees beside the bed, bowing and apologizing profusely, for reasons that they honestly hadn't been able to control at all.
"No, no, no. It's all my fault. I didn't notice when Risa switched our rooms out, Shuna. I'm sorry. I bet neither of you expected to wake up in my house this morning."
"Oh, no, Lord Rimuru! Waking up here is a real honor, a dream come true!" Shion told me excitedly. A moment later, her eyes widened, and she put a hand over her mouth, realizing what she'd just said could technically be counted as a confession. Not even Shion's dense brain could ignore that fact.
"Umm…" I hesitated, then decided to gloss over it, for the sake of my own sanity. "Okay, then. Don't worry, I'll fix the room and send you two back to your own places right away. We can just forget this whole incident, alright?"
"Un!" Shuna made a small noise, like a grunt.
"Shuna?" I asked.
"...Do we have to?" She whispered it so quietly that I was almost certain that not even Shion had heard what she said, but I couldn't miss it if I tried.
That one sentence hit me like a truck. "Shuna… Shion…"
…
Due to the way that Risa had swapped portions of the rooms with Horus, my bedroom was currently a mess of twisted, folded space. Basically, a hatchet job done by someone with a complete mastery of all things space-related. While a normal eye would only notice small things, like the small corner of my rug being pink, from Shuna's room, or the fact that there were small purple patches, from Shion's blanket, on the bed that'd been pulled from Shuna's room due to the fact that my own bed was slime-sized, it felt like some sort of terrible insult to my own Demon Lord senses, which could tell exactly where the fabric of space had been pulled apart and stitched back together like a jigsaw puzzle designed by a lazy person.
For example, there was a small spot near the side of Shuna's dresser where there was a tiiny spatial portal, which allowed about five atoms worth of space to exist in three different rooms at once: Mine, Shuna's, and Shion's, all three. Just looking at it drove me absolutely insane for no reason at all.
So, I pulled everything in all three rooms into my stomach with Belzebuth, then fixed the space, before replacing the important stuff.
The girls' dressers, along with all of the clothes in their closets, all ended up in my room along with Shuna's bed.
I ended up having to use Dominate Space to turn my closet into a walk-in one in order to hold all of the girls' clothing.
