"What a convenient power. In that case, I won't hold back. I'll take the last room on the second floor."
"That still sounds like you're holding back, but fine, whatever you like. As for furniture—just let me know what you want and I'll construct it for you. No need to wait on deliveries."
In Elias' hands, the Herrscher of Reason's power glowed brilliantly. If he entered the construction industry now, he could probably obliterate every architecture firm on Earth.
After all, a power capable of constructing anything? Practically tailor-made for the infrastructure-obsessed.
But to his surprise, a few others also joined in, picking out rooms.
"Then I want the first bedroom on the ground floor. Oh, Elias, can you make me some life-sized Homu pillows too?"
"We'll take the first two rooms on the second floor."
"Eh? Why am I involved too~?"
Theresa, Ji Xuanyuan, and Fu Hua all chose rooms in the expanded dorm, instantly taking up half of the newly available space.
Elias looked at them in surprise. Ji Xuanyuan made sense—he had brought her back intending for her to stay. But what were Theresa and Fu Hua doing?
Next second, Theresa crossed her arms and pulled a device from her nun robes. It played a recording sent by Siegfried.
"Of course the principal is moving in. Someone has to monitor Elias. I heard you're treating my niece like a pet. I can't allow such impure, cross-gender mingling!"
"Siegfried... you... Wait—is this a good thing or a bad thing? Actually, this might be a good thing."
Elias was about to get upset.
But then he paused and realized—what was there to be upset about?
His first instinct was that Theresa would somehow mess things up. But really, what could a tiny rocket-propelled nun possibly mess up?
Besides, he had a clear conscience and fists to back it up. Nothing to fear.
And from another angle, it just meant another (outwardly) cute girl living in the dorm.
In fact... thank you, Father-in-law Siegfried, for the gift of this legal loli! How could there be a better blessing?
"Lord Elias, I request a room change. May I stay next to Lady Theresa?"
"Now you're being honest. Sure, go ahead."
"Eh?! Rita, what are you up to?!"
"Hehe~ Just taking care of you like I always have."
The moment Rita heard Theresa would be moving in, her eyes lit up.
This loli-loving maid had found new meaning in life.
Elias couldn't help but think that winning Rita's absolute loyalty might be easier than expected. If he just told her he could give Theresa actual cat ears and a tail, she might die from moe overload.
At this rate, the dorm just gained two more future Herrschers! Welcome the future Herrscher of Sentience and Herrscher of Desire! Truly worthy of the title: Herrscher Academy.
"Um, Ji Xuanyuan, I have my own dorm. I don't need to live here."
Fu Hua waved her hands, trying to excuse herself.
"But Jingwei, isn't living alone lonely? Isn't it a bit antisocial? Look how lively it is here. Join us!"
"I, well..."
"Ji Xuanyuan is right, Fu Hua. Why don't you move in? We've got plenty of space now."
Even Himeko joined in.
And as the eternally honest one, how could Fu Hua resist the kindness around her?
Maybe she really did feel a bit envious of the warm, bustling atmosphere.
In the end, under everyone's expectant eyes, she agreed to move in.
With Elias' power, Fu Hua, Ji Xuanyuan, Rita, and Theresa quickly settled into their new rooms.
Elias looked at the flock of beautiful girls fluttering around and couldn't help but feel... delighted.
This must be Valhalla—the paradise of fair maidens that even fae maidens would dream of!
Welt, who had originally planned to stay the night, promptly decided to leave after seeing the scene before him.
Before departing, he left behind a sarcastic comment:
"You kids these days really live wild. Honestly, this is less a dormitory and more Elias' harem. Ahem, I said nothing. Goodbye."
He didn't dare linger.
Because Elias had been looking at him strangely.
A kind of look that screamed "I might just rip your core out next".
(Didn't he already get a core from the Previous Era? Why is he still eyeing mine?) Welt thought anxiously.
In truth, that's exactly why Elias wanted his core even more.
The Herrscher of Reason was extremely special—achieving ascension was far trickier than with other Herrschers.
Even if he could use the core from the Previous Era smoothly, it would never be enough to reach the realm of the Herrscher of Truth.
So Elias had come up with a cheat method:
Fuse a second Reason core.
Force resonance between the two, elevate output to a level beyond the sum of their parts, and possibly attain the full form of the Herrscher of Truth.
"He ran fast. I didn't even say I wanted it now. Whatever. I'll get it eventually."
With a shrug, Elias picked up the USB Welt had left behind and began studying it.
Inside were Welt's experiences with the Herrscher of Reason's power—weapon construction techniques, and designs.
Including Star of Eden... and Moonlight Throne.
The former was well-known, but the latter immediately caught Elias' interest.
The weapon that once shattered thirty percent of the Herrscher of Finality's Honkai energy—a supermassive cannon from the Previous Era.
He'd always been fascinated by it. And the name? Extremely cool. Elias loved it.
Of course, constructing a full Moonlight Throne without having ascended as a true Herrscher of Reason was absurd.
In the original timeline, Bronya had pulled it off—but nearly died in the process.
Fortunately, Dr. Einstein and Dr. Tesla had created a downgraded version: Moonlight Throne: Floating Cannon.
Only a twentieth the output of the original, and still highly complex.
But after reviewing the schematics, Elias felt confident he could construct it—with time.
"Even without battleship-level firepower, thanks to its special attributes, a floating cannon version of Moonlight Throne could probably one-shot an elite Honkai Beast. That's perfect!"
Elias sighed in relief. This power was as good as he'd hoped.
He had been a little worried at first—what if a power that required brains just didn't suit him?
After all, his usual style was to charge in with a fire-element greatsword and smash smash smash.
It's not like he could Trace On a pile of cold weapons and fling them around like a certain righteous mage, right?
...Though that did sound kinda cool.
But that kind of thing was beneath a Herrscher of Reason!
He wanted lasers! Missiles! Floating cannons! Mecha!
That was the true romance of a man!
"Wait a second—beautiful girls, dragons, mechs... I've collected all three of the ultimate male fantasies!"
Elias blinked.
He had Raiden Mei—and a harem full of girls waiting to be spoiled.
He had Benares—even if she wasn't around at the moment, their reunion was inevitable.
And now, he had the ability to craft mechs at will through his Reason powers.
"Suddenly, I feel like life has no regrets left. I'm satisfied~"
Elias lay contentedly on his large bed, muttering to himself.
Even in this idle state, he continued studying the knowledge required to master the Herrscher of Reason's power—namely, the structure of powerful weapons and equipment.
The Herrscher of Reason came with built-in analysis capabilities.
Even without foundational knowledge, Elias could gradually understand blueprints just by staring at them.
And once he constructed a weapon once, his body would remember it. The next time? It would be as smooth as breathing.
"I should probably decide on a development path. Welt's style of building an entire futuristic army and flooding the battlefield with firepower is definitely cool."
"But I still prefer Bronya's approach—constructing specialized weapons to exploit enemy weaknesses."
"Ah, forget it. I'll do both."
Elias promptly gave up trying to choose. As a proper adult, the right answer was clearly all of the above.
It just meant memorizing more stuff. But his brain was far more advanced than the average person's.
Thanks to the Herrscher of Rebirth's continuous body optimization, Elias' mental faculties had developed tremendously.
He couldn't increase his innate insight, but he now possessed perfect memory. Combined with the Herrscher of Reason's analytical boost, learning was effortless.
Put simply, even if Elias were a grade-schooler, give him two or three days and he could self-study into a top-tier university.
After all, memorizing, understanding, and constructing were as natural to him as breathing.
"If I'm going with Bronya's route, I need a deployment terminal to fully utilize my powers... Got it!"
Elias' eyes lit up, and he sprang from bed.
He rushed to the living room and found Bronya on the couch playing games with Kiana.
He patted her head with a grin.
"Little Duck, time for a power-up."
"What?"
"Project Bunny 19c—UpGrade!"
Elias summoned Bronya's Project Bunny. During his second time-space leap, he had acquired control over the quantum mecha, and his access level was even higher than Bronya's.
Under the reconstruction of the Herrscher of Reason's power...
Project Bunny underwent a legendary transformation. No longer a simple white starter model, it now gleamed in the same dazzling form from Bronya's Herrscher transformation in the original story!
A sleek combination of ocean blue, pure white, and mechanical black. Its limbs more agile, wheels deployed beneath the frame, four thrusters on its back, and countless armaments upgraded to cutting-edge.
"The new system is ready!"
A synthesized female voice echoed from Project Bunny 19c.
It sounded like it was celebrating its new powers, engines roaring with vigor.
"Wha—what is this?!"
"Whoa! That Project Bunny looks so cool!"
"Did it evolve under the influence of the Herrscher of Reason? I think it might outperform all of Schicksal's mechs."
"I bet it can transform too!"
The girls in the living room stared in awe, amazed by its stunning new look.
And it wasn't just for show—its performance had increased by over a hundredfold.
But that wasn't all.
"Now that Bunny's upgraded, it's your turn, Bronya. Ready?"
Elias turned to Bronya with gentle affection.
She didn't fully understand what was happening, but she knew exactly what to do in this moment.
Without hesitation, Bronya dove into Elias' arms, wrapping her arms around his neck and speaking with anticipation.
"Mm! Bronya is ready!"
"Excellent. Then, let this be the Cyberangel!"
Elias channeled the Herrscher of Reason's power into Bronya's outfit. What had been an ordinary Valkyrie uniform transformed into a stunning blue-and-white mech-themed dress.
The upper half became a fitted suit of blue and black armor. The lower half a white ruffled short skirt over a long black tailcoat. Add white stockings and matching heels.
Bronya's short drill-like hair lengthened into waist-length tresses with four distinctive turbine curls.
A silver crown-like hairpiece appeared atop her head, and a bright blue gem glowed at her chest.
"This is way too pretty..."
"Bronya-sis, you look just like an angel!"
"Whoa, Elias! You're totally playing favorites!"
Elias smiled and waved his hand, conjuring a full-length mirror before Bronya.
"Is... is that really Bronya?"
She stared at her reflection, stunned. She felt like she was dreaming.
In the mirror, she looked like a lovely princess—just as Seele had said, a heavenly angel come to Earth.
Bronya had never imagined herself like this. Perhaps due to her years as a child soldier.
Rather than thinking of herself as a girl, she subconsciously saw herself as a soldier.
You could tell just by her outfits. Despite being such an adorable girl, she always wore suits and skirts or other more masculine attire.
But this dress Elias had created for her made one thing very clear: she was beautiful. Even fairy tale princesses couldn't compare.
"As expected of my little duck. Perfect~"
"Papa Elias, what is this outfit?"
"Originally a Herrscher of Reason battle suit. I modified it to suit you, Bronya. Don't be fooled by the looks—its performance rivals Schicksal's Godsbane Suits. And it puts no burden on the user."
Elias tapped Project Bunny 19c's massive body.
"It's linked to your mech. Normally it won't appear, but when you summon Project Bunny in combat, the suit will automatically equip."
"Also, any weapons I construct for use via Project Bunny, you can use as well. After all, that's your tactical mecha."
As he spoke, Elias casually constructed two "Keys of Truth" laser cannons and mounted them onto Project Bunny 19c's shoulder armor.
Then he returned the control of Project Bunny to Bronya. She quickly realized she could now use those heavy laser cannons as well.
Everyone stared at the scene in stunned silence.
No one had expected this kind of operation.
"Amazing. This actually works?"
"She can share Elias' weapons through Project Bunny? It's like Bronya became a Herrscher of Reason too."
"I think the key here is that dress. Elias, you really went all out!"
Himeko and Theresa were dumbfounded.
Kiana looked on with envy.
First the Bunny upgrade, then the battle dress. Kiana felt like her status as Elias' most-pampered might be slipping away.
"Papa Elias, all this just for Bronya..."
Bronya's heart pounded as she was overwhelmed with emotion.
Elias shook his head with a warm smile.
"Honestly, Bronya, I think you should've been the one to inherit the Herrscher of Reason core. But since Welt won't give it up, I had to find a workaround."
"So let me become your Herrscher of Reason."
He embraced Bronya and sat atop Project Bunny 19c's frame.
The image was that of a prince holding his princess, riding upon a mighty steel steed—a bunny-shaped one.
