2. Interpretation of the World and the World System
“Eh?!”
Shiro gasped at the sudden shift in his surroundings.
The world around him had turned into a featureless white void. To his right, multiple screens appeared, displaying various scenes and status updates.
“This is the administrative room of the Filidia world. The operational status of the world system is displayed here. You’re familiar with these screens, aren’t you, Shiro?”
Shiro stared at the screens, murmuring.
“…Those screen layouts are eerily similar to my own design…”
The sudden, surreal phenomenon left him bewildered. Unaware or not, Firumia continued speaking.
“We’ve temporarily connected your soul’s external interface channel to this space.”
“…External soul connection…?”
“In fact, the Filidia world is the first ever built using what we call the fourth-generation world architecture. And its foundation? It’s based on the system you’re currently developing.”
“My architecture as a foundation? But I just finalized the development today?”
“Fufu. Yes, indeed. The worlds operating in the divine realm were previously known as third-generation. But we discovered that your design is remarkably similar—no, even superior—to those earlier models.”
Firumia explained, then continued.
“And in fact, we’ve been gradually borrowing your design philosophy for a short while now, integrating it into our own. That’s how the fourth-generation system came to be—and we’ve only just begun creating and testing it.”
“Fourth generation?” Shiro muttered.
"Yes. In truth, Shiro’s interpretation of the world’s architecture is largely correct. And his design is ahead of our own. That’s why we’ve come to recognize Shiro as a fellow architect of the divine world—and secretly hoped for a collaborative development."
Firumia spoke with genuine delight.
The divine world’s design? Collaborating with gods? Could that really be possible? Shiro was stunned.
"Um, I’m flattered to be of help, but—what exactly does this 'invitation to the world' entail?"
"Yes, as I mentioned earlier, gods cannot directly interfere with the world. Not exactly—there are limits. They can monitor, make structural adjustments during system updates, and offer guidance to local Miko through divine oracles.
Additionally, while there are deities specialized in individual modules, no god comprehends the entire system from design to implementation.
That’s precisely why Shiro, who personally handled every detail, is such an ideal candidate for troubleshooting the world system—understanding the world’s principles as if he were divine himself, despite being merely human."
Firumia continued, her gaze earnest.
"In the Filidia world, we’re currently facing a serious issue with monsters—malevolent creatures imbued with magic. There’s growing suspicion that this is due to a system bug.
Yet, even with the gods observing from the administrator’s chamber, the root cause remains elusive. And we’re unable to eliminate them. Such a situation—where even the divine can’t grasp the problem—has never happened before."
I’m the architect of the third-generation system myself, and even I’m stuck—completely unable to resolve this. So I thought, perhaps you, Shiro, the most qualified person available, could be transferred directly into the world and conduct investigations, adjustments, and even rescue operations from within?
Firumia explained with a serious expression.
“Hmm… that sounds a bit out of nowhere… Aren’t monster outbreaks dangerous? It’s not a game, is it?”
Shiro hesitated slightly at the mention of monsters.
“Don’t worry—once you’re there, you’ll have access to appropriate magic and skills. The risk should be manageable.
Incidentally, the world’s setting is a fantasy realm—sword and magic style, just like the one you originally designed. The basic magic infrastructure and fundamental spell templates have already been implemented. It’s peaceful enough for now—just not counting the monster problem.”
—So monsters really are bad then… what happens if I die…?
Shiro suddenly felt uneasy.
Whether she noticed his discomfort or not, she continued.
“So, in short, we’d like you to handle troubleshooting, and—while you’re at it—take a little sightseeing tour, and also install a new magic system.”
—Sightseeing, huh. Sounds light. But kind of fun. Still… installing a magic system?
Shiro suddenly found himself intrigued. He couldn’t resist anything labeled ‘system.’
“What exactly do you mean by installing a magic system?”
“Yes. Currently, in the Filidia World, only basic magic is usable. But originally, it was meant to support more complex magic—‘spellcraft’—so we’re asking you to help install and spread knowledge of the system.”
“Hmm… it’s hard to believe all this right away… I mean, I can’t exactly disbelieve it, since I’m actually experiencing this white space myself.”
“Fufu. That’s true. There’s also a benefit for you, Shiro.
First, you’ll be able to experience and tour a completely immersive alternate world—something far beyond today’s VR systems on Earth, and impossible to achieve with current Earth science.
And your developed auxiliary AI, database, and specialized development system can all be granted as skills. We’ll include world-coding environment, assistant pseudo-personality integration, and development documentation unification too!”
“…I see.”
Shiro thought it was incredibly compelling.
Current Earth VR technology won’t achieve true “full-dive” systems—those fully immersive, sensory-neural interface types—for quite some time.
Whether it’ll even be possible in Shiro’s lifetime is questionable. And even with full-dive tech, it’s still just a simulation. To actually experience your own created system as a real world? That’s not something you can just do.
This white space here—its realism is practically unbelievable.
—And a pseudo-personality? That’s still a field I haven’t cracked yet!
Shiro, who tends to lose focus when it comes to things he’s interested in, felt a flicker of excitement.
But he kept his voice steady.
“That… is quite an appealing proposition.”
“The Filidia world, at present, isn’t compatible with physical bodies on Earth, so we’ll apply a conversion process to give you a sturdier form. Also, the World Development Tool skill is quite powerful, so feel free to develop your world however you like. Though, of course, destroying it entirely would be a problem.”
The goddess smiled.
She clapped her hands together again, fingers snapping sharply.
And suddenly, the two of them were back in the living room of Shiro’s house.
Shiro, then, suddenly thought of something and asked.
“While I’m in that world, what happens here? I’ll be gone for a long time, right?”
“No,” the goddess said. “The flow of time between Filidia and Earth is vastly different. Even if you spend a year there, only about one day passes here. Currently, the time ratio is set at roughly 400:1—Filidia to Earth. That said, the flow of time can be adjusted at any time for reasons related to divine affairs or development, so we can’t guarantee it’ll stay exactly that ratio.”
—Hmm, time flows differently and can change? Sounds familiar. If it’s just a few days in Earth time, the house should be fine.
Shiro thought casually.
“Ah, I see.”
He nodded, accepting it with a quiet understanding.
“For now, we’ll transfer you to a remote area—a sacred site in the other world. A cabin’s already prepared. I’ll also set up the world’s data for you. Start by checking things out there.”
Firumia spoke with a peculiar expression—part mischievous, part certain—and gave a small, knowing smile.
Truth be told, Shiro’s decision had already been made. The idea of refusing hadn’t even crossed his mind.
“Understood. I’ll take it.”
Shiro answered clearly.
“Thank you!”
Firumia turned a radiant smile toward Shiro. Dazzled by her unearthly beauty—his gaze couldn’t tear itself away—
“S-so, then… when exactly will we be leaving, do you think?”
he asked, thinking it best to prepare a little before departing.
“Hmm, how about two o’clock the day after tomorrow?”
“Yes, understood. I’ll just wait here at the house, right?”
“Yes, that’ll be fine. Then, see you then!”
With that, Firumia turned and left.
Shiro would spend the next two days busy with preparations.
