High School Dxd: Word of Creation

Hiyama's Mansion, Kuoh town –

POV: Hiyama Oreki –

Arriving home after the conversation with the Kuoh devils, I immediately went to the lab beneath the mansion. The lingering echoes of the discussion reverberate in my mind, but I push them aside. There are two critical objectives I must accomplish before the mission tomorrow, if my plan is going to work.

First, I need to finish learning how to create additional mouths. With the extensive biology research I've conducted with thought acceleration, it shouldn't be too challenging. Second, and more importantly, I must figure out the mechanics of memory partitioning – a technique that will allow me to multitask. If I want to be able to take advantage of having multiple mouths to use Logos Reverie then it is a requirement.

I pace around the lab, the soft hum of magical machinery filling the silence. The fallen trio, but Raynare in particular, have been hard at work. They did exactly as I asked, creating various magical machines that perform various tasks. There was the sacred gear machine, that I still haven't had the chance to use, and the magical enhancement machine.

But there were others now, one was for extracting and studying genes, and another was a medical station. The rest were incomplete, but I was going to give plenty of ideas for that.

Diagrams and anatomical sketches of vocal cords, nerves, and mouth structures are scattered across the workbench I was using. Focusing my thoughts, I extend my right hand and begin constructing a magic circle. Golden runes shimmer as they take form, spiraling in intricate patterns as I carefully guide each cell into its designated place.

I construct the formula slowly, piece by piece, mentally forming the algorithm that creates miniature vocal cords, a tongue, and lips. The energy crackles faintly as the golden glow intensifies, signaling the activation of the spell. When the light subsides, I look down at my left hand. Embedded within my palm is a mouth, complete with teeth and fully formed vocal structures.

Cautiously, I attempt to speak. Nothing. I frown, flexing my fingers because of the weird sensation, and try again. Two hours pass in experimentation. I refine the formula, tweak the circle's construction, and repeat the process. Finally, after countless attempts, the mouth twitches to life.

"Hello," I say through the hand-mouth, the sound distorted but intelligible.

A grin tugs at my lips, but the real test is yet to come. I gather my magical energy, concentrating it within my palm as if casting a spell through my normal mouth. The sensation is strange, but I focus on the target – an empty chair across the room. I press my hand forward, commanding with the Voice.

"Float!" The chair trembles before lifting a few inches off the ground. Success.

But one mouth isn't enough.

If I'm to wield Logos Reverie to its fullest potential, I'll need more. Multiple voices working in harmony could allow me to cast several spells simultaneously or reinforce the power of a single spell through layered incantations.

I craft another circle, this time targeting my right shoulder. With each attempt, the process grows smoother. Soon, a second mouth forms just beneath my collarbone. This one activates almost immediately. I test it with basic commands, letting it speak independently of the hand-mouth. The voices echo eerily but operate as distinct entities.

I still can't use multiple at the same time though… Welp, now for the hard part – memory partitioning.

I sit at the workbench, gathering my notebooks and magical texts on neurological functions. I got them all from Mittelt last time she went to the Underworld earlier this week.

Memory partitioning isn't just about multitasking. It involves dividing one's consciousness, allowing each 'partition' to function autonomously, like creating sub-processes in a computer. The goal is to divide my awareness into separate compartments, each capable of running spells, analyzing data, or crafting magical constructs without interfering with the others. This will allow me to give a compartment for each mouth to independently function.

I close my eyes and slip into a meditative state, visualizing the flow of my thoughts. I can feel the creation of a magic circle in front of me, but I keep my eyes closed. I picture my consciousness as a vast library, each shelf representing different processes and information. With careful precision, I begin erecting mental barriers between the shelves, isolating certain thoughts and tasks.

The first attempt fails almost immediately. The mental strain is overwhelming, leading to a splitting headache. But I press forward.

What I need is to reinforce the partition to make it permanent. I can feel that I'm making the partition, but it immediately dissipates when I try to use it.

I adapt the process by using magic to reinforce the mental barriers, shaping what would appear as threads around each partition. Minutes bleed into hours, and progress is agonizingly slow. However, with each failure, I refined the approach, borrowing from what I knew of the Fate Universe and my knowledge of Mind Magic.

Finally, something shifts. I sense the formation of the first partition, a small yet distinct segment of my mind that hums separately from the rest. Testing it, I assign it the simple task of vocalizing a continuous stream of basic magic like creating a small sheet of ice.

Simultaneously, I engage the hand-mouth in levitating objects. The coordination is clumsy at first, but soon the tasks run in parallel. I bring certain objects closer, then coat them in ice, before sending them away again.

Encouraged by the breakthrough, I attempt to create a third partition. This one proves even more challenging. The mental strain resurfaces, but I push through, weaving the mental threads to secure the partition in place.

When the third partition settles, I let out a breath I hadn't realized I was holding. Sweat drips down my forehead, but the sense of accomplishment outweighs the exhaustion.

"Float."

The word resonates from three sources simultaneously – my mouth, the hand-mouth, and the shoulder-mouth. The chair jolts upward, smashing against the ceiling. I dispel the command quickly, allowing it to crash back down with a loud thud.

"A bit too much power," I mutter, shaking my head. Control will seem to be an issue when using memory partitioning.

I sit down, fatigue seeping into my bones, but the exhilaration lingers. I've crossed a threshold today. With memory partitioning partially mastered and multiple mouths functioning, my potential has grown exponentially. Effectively with three partitions I can perform four separate lines of thinking. Now I will be able to carry out my plan.

I intend to use Logos Reverie to create a massive storm to fuck the building and its defenses up. That's why I really needed multiple mouths, creating a storm on the level I wanted while also directing it to specific areas as needed would be difficult with one sentence. I would have one partition focused on creating the storm, another directing it, another to protect myself. The remaining one will stay in reserve just in case.

It was getting pretty late by the time I was completely done, when I left the lab I found Kala getting ready to enter the underground bathhouse. She wore her maid outfit as usual, her ample breasts almost spilled out.

Noticing me she said, "Would you like to join me, master? You haven't done anything but sit in the lab since you got home…" She was clearly teasing me. Oh hell, might as well I wasn't going to do anything with her yet anyway.

Moving towards the bathhouse with her we enter the dressing room. I move to take my clothes off, but she stops me. "No, I'll undress you." So, she begins to take my clothes off, starting with my shirt, then undoing my pants pulling them down.

While on her knees she takes my underwear off she reaches for my tool, but I catch her hand.

"Not yet..." Obviously disappointed with me not allowing her to go any further she stands up to take her clothes off. I watch her closely and she makes no attempt to hide herself. Once she releases her enormous breasts, my nether regions go to full sail. When she is finally completely naked, we make our way to the warm baths.

The place is massive for a bathhouse underground. It is made mostly of stone, with statues of busty angel women with jugs pouring warm water into the bath. The bath itself was massive, there were technically several baths, but they were on three different tiers. The largest was at the base level, being larger than any pool I've seen.

But we instead walked up the steps to the side to get one of the third level tubs. It was bigger than any normal hot tub, but not enormous.

Once we had gone in, I felt an overwhelming relaxation sweep over me. Kala made sure to sit right next to me, as I placed my arms on the edge and leaned back with my eyes closed.

"Master?" Kala called quietly. I opened one eye to acknowledge her to continue. "Why are you helping the devils?" She tried to say it sweetly, but I could tell she wasn't too pleased about them.

"It's always good to make allies." I responded.

"They are devils. Creatures of lust and greed." She spat.

"How were you any different when I took you into my service? It's only been two weeks since you came into my service. I doubt you changed much." I chuckled a bit. The fallen were always arrogant, they couldn't acknowledge that they were no different. She at least had the decency to look ashamed.

"I was just following orders…" She said quietly.

"How many atrocities have been committed because someone was just following orders?" I countered. She needed to develop some type of morality to decipher her actions, she can't just blindly attach herself to the strongest person nearby. Raynare may have been the most extreme example, but the other two weren't far off.

Each one took a different approach when attaching themselves to me, as the powerful individual in their life. Raynare has fallen in love, Mittelt being a perfect servant that follows me silently everywhere, and Kalawarner was somewhat of a mystery in between the other two.

"I don't know how to approach being your servant, master." She sounded disheartened. "Most people would treat their servants like objects, especially for one that looks like me." She gestured to her very large naked breasts. "I don't know whether to be a soldier or a maid, or-"

"You want to be told what to do." I cut her off. I was starting to understand now, she was being told what to do her entire life. Never making any decisions for herself. Always deferring to the next rank up. Even with Raynare, despite being friends, she was clearly subordinate.

I continued, "I won't be telling you what to do. There is nothing wrong with having superiors, but you have to be capable of making independent decisions." She nods at my words, she clearly needed to think a lot. We sat in silence before she spoke again.

"Well, would you like me to wash you?" she asked.

"Why not?" I might as well enjoy some of the perks of having a loyal servant.

After getting my permission she grabbed a box of soaps and other cleaning tools. She washed me, and then I washed her while having small conversations about various topics. She also elected to give me a massage as well, which was much appreciated.

Once we had finished we got dressed for bed, as she followed me to the rooms upstairs.

I bid her farewell as I went into my room and slept…
