Arrival in an isekai

"How are authorization levels are assigned and what criteria determine capability assessment?" Renner asks setting down her teacup gently, her analytical attention sharpening as you begin your explanation.

"The two questions have very different answers, easier to address in reverse order," you state while gesturing toward the assembled household members. "An individual's power can be determined many ways between magical, political, physical, intellectual, et cetera. The context of power is being able to create results from that capability."

"A useful framework," Renner acknowledges. "Please continue."

"For a good reference, your adventuring system uses eight ranks from Copper to Adamantine. Convert each rank into five levels from one to forty. The maximum is standard at one hundred, a point your world only experienced from the historical players the Slane Theocracy calls their six gods."

Renner's eyebrows raise fractionally. "You're suggesting those legendary figures operated at capability level one hundred?"

"I'm confirming it," you reply simply. "And I operate on the same scale."

The princess absorbs this statement without visible reaction, though her fingers tap once against the table. "That provides useful context for understanding your operational confidence. What determines authorization levels?"

"Authorization levels need to be earned from an individual's capabilities," you explain. "The Manor residents are mostly mundane, less than copper plate, or have limited adventuring experience. Their current access is almost only Amagi Park because it's the only place safe for them beyond here."

Arche glances up from helping Ureirika with arithmetic problems. "Lord Blank assessed my magical capabilities before we met. There are no worlds we have reason to enter that are currently dangerous."

"I appreciated the thoroughness," Arche continues. "Most nobles would simply assume magical training guarantees safety. Lord Blank is actually going to train us using worlds of slowly increasing danger."

You gesture toward Albedo and Ikaros standing near the wall. "Others such as Ikaros and Albedo would easily overpower most challenges and are allowed almost everywhere. Their capabilities exceed threats they'd encounter in conventional locations."

Renner studies both women with renewed interest. "Albedo's administrative authority suggested significant capability, but I had not estimated her personal combat potential as comparable to legendary historical figures."

"She commands Floor Guardian authority within Nazarick," Albedo confirms with quiet pride. "My combat capabilities match my administrative responsibilities."

Ikaros remains silent near the wall, wings folded against her back, but Renner's analytical gaze lingers on the visible angelic features.

"This explains the clothing variations I observed earlier," Renner notes thoughtfully. "Residents with limited combat capability wear modest or comfortable attire for secured environments, while those with greater power demonstrate confidence through varied presentation."

"Partially correct," you acknowledge. "Clothing choices also reflect individual circumstances, psychological disposition, and specific instructions I've provided. The correlation between power and presentation isn't absolute."

Kallen shifts uncomfortably in her red bunny suit, drawing Renner's brief attention. The princess processes this visible contradiction without comment.

Neia speaks up from further down the table. "The Sacred Kingdom maintains extensive fortifications because our military lacks individuals operating at higher power tier. Master Blank's framework makes our strategic limitations easy to understand."

"Your military operates primarily between levels ten and twenty-five," you confirm. "With rare exceptional individuals reaching thirty. That handles most threats from your level, while exposing vulnerability against threats operating above or outnumbering your defensive threshold."

Renner folds her hands in her lap with practiced elegance. "The Re-Estize Kingdom's military capabilities fall within similar parameters. Warrior Captain Gazef Stronoff represents our highest combat capability, likely operating near level thirty based on your framework."

"Slightly below," you correct gently. "Gazef operates effectively in the high-twenties. Still exceptional by local standards, but insufficient against threats operating significantly higher."

The princess absorbs this assessment without visible reaction. "That explains why your intervention at Carne Village proved decisive against the Sunlight Scripture. They operated above Kingdom military capabilities but far below yours."

"The Sunlight Scripture's leader Nigun should have been low thirties," you confirm. "With subordinates ranging between twenty-five and thirty. Effective against conventional military forces, trivial against level one hundred. Much less my excessive power hoard."

Milly leans forward with visible interest. "How do you assess capability levels so precisely? Is there a magical scanning technique?"

"Multiple methodologies," you reply. "Direct observation of spell casting, equipment analysis, combat performance evaluation, and specialized appraisal magic. Combined data provides accurate capability estimates."

Renner's analytical expression sharpens. "You've systematically evaluated Kingdom military capabilities through these methodologies?"

"I've evaluated everyone I've encountered directly," you confirm. "Plus analyzed the story-timeline progression describing individuals. The data proves useful for operational planning."

The princess processes this information while continuing to eat with precise movements. "Your authorization framework balances security against individual agency. Residents gain access to locations matching their capabilities rather than facing arbitrary restrictions."

"Correct," you acknowledge. "As residents develop greater capabilities through training or experience, their authorization will expand accordingly. The system rewards growth rather than enforcing permanent limitations."

Enri approaches from the serving counter carrying fresh tea. "Princess Renner, would you like anything else? The enchanted feast maintains everything perfectly, but I can request specific items."

"This remains adequate, thank you." Renner accepts tea while maintaining her focus on you. "I have additional questions about capability development and training opportunities, but perhaps those discussions would benefit from observing household operations directly rather than continued theoretical explanation."

You set down your teacup. "I'd suggest you participate with the Carne Village's teaching and training classes alongside the Manor residents starting tomorrow instead of merely observing. Learning a self-defense method, be it martial or small weapons, is a requirement for surviving the progression through worlds. Should you accept a place in this, you will also be required to learn the minimum to defend yourself. This will also give you the opportunity to spend time with the girls, though I imagine finding time will be a difficulty. I hope the portal-mirror makes it easier."

Renner's analytical expression sharpens with interest as she processes your proposal. Her fingers tap once against the table before she responds. "You anticipate I would accept recruitment, then proceed to enforce minimum combat capability standards. That suggests genuine concern for participant safety rather than merely collecting assets."

"I don't collect people who can't survive their circumstances," you reply evenly. "Training exists because worlds vary considerably in danger levels. Someone without basic defensive capabilities would die quickly in certain locations, regardless of how powerful their companions might be."

Arche speaks up from further down the table. "Lord Blank arranged magic instruction for myself and combat instruction for my sisters through the village school. Instructor Fenrak teaches basic defensive techniques appropriate for noncombatants. The training focuses on situational awareness and escape tactics rather than expecting us to defeat trained warriors."

Kallen shifts in her red bunny suit, drawing Renner's brief attention. "We've haven't had time to attend the classes so far, but I know they exist. Probably should start attending before someone drags me there forcibly."

"No one will drag you to the classes," you correct gently. "Though continuing to avoid training will put yourself at risk when I begin your adventures. Your survival will determine your authorization levels."

Renner absorbs this exchange before returning her focus to you. "The training requirement applies universally to household members regardless of their other capabilities or contributions?"

"Combat capability determines survival probability," you confirm. "Political acumen or intellectual analysis won't stop blades or fangs if you're caught alone in dangerous territory. I prefer residents develop minimum defensive skills rather than remain perpetually dependent on escorts."

Albedo leans forward slightly. "Master Blank established tiered authorization precisely because different residents possess varying capability levels. Training provides pathways for expanding individual access rather than enforcing permanent restrictions."

Milly takes in a slow breath beneath the modified maid outfit. "I've been considering attending the classes myself. My analytical capabilities won't help much if I encounter physical threats during diplomatic missions, and we've already been warned the weapons from our scientifically advanced homeland won't be available to us."

Renner's gaze tracks across the assembled women, noting their varied reactions to the training discussion. "You mentioned the portal-mirror makes scheduling easier. Do you anticipate I would maintain my position within Re-Estize while simultaneously participating in household activities?"

"That depends entirely on your decision," you reply. "The portal allows flexible scheduling if you choose to maintain your castle responsibilities. Other residents have transitioned fully into household operations, abandoning previous positions entirely. Individual circumstances determine appropriate arrangements."

The princess sets down her silverware with precise movements. "I would need to observe the training sessions before committing to participation. Understanding instructional methodology and capability expectations seems relevant to my decision-making process."

"The village school conducts afternoon training sessions starting at two o'clock," you inform her. "You're welcome to observe whenever you wish. Just remember to change your clothing before leaving the manor."

You rise from your seat while Princess Renner continues questioning Arche about the village school curriculum. "Albedo, Ikaros, accompany me to the library. lets observe Grayfia's diplomatic demonstration firsthand."

Albedo stands smoothly, her elegant bearing drawing brief attention from several household members. Ikaros unfolds her wings slightly before following, the celestial presence unmistakable as she moves.

Renner glances up from her conversation, analytical eyes tracking your departure. "Should I expect your return, or continue observing household operations independently?"

"Feel free to explore as you wish," you reply while approaching the main hall portal. "The manor residents can answer most questions about daily routines."

Alicia waves cheerfully from her seat, the blue bikini armor catching light. "Princess Renner, we'd be happy to show you the clothing manifestation if you're curious. It's genuinely remarkable once you see it."

You step through the dungeon passageway with Albedo and Ikaros following close behind. The transition between dimensions barely registers as you emerge into Nazarick's throne room, then proceed directly toward the library floors.

Jibril glances up from her research table as you enter the vast multidimensional space, scrolls and crystalline data storage devices scattered across the surface. Irene sits beside her, red hair falling across scarlet-scaled patterns visible along her neck.

"Master Blank," Jibril greets with visible pleasure. "What brings you to the library during working hours? I assumed you'd be managing household integration with the new diplomatic observer."

"I finished what can be done there. Now I intend to use the Infinite Stratos portal to scry," you state while approaching the permanent gateway anchored near the research section. "Grayfia's demonstration should be starting shortly. I want real-time observation without alerting anyone on the other side."

Irene rises gracefully, her enchantress robes shifting with the movement. "A simple modification. The portal already supports bidirectional visualization."

She gestures toward the gateway, fingers tracing complex patterns in the air. Magic flows from her hands into the portal's silver edges. The shimmering surface shifts from opaque transit medium into transparent viewing window.

The Paris hotel conference room materializes clearly through the modified portal. Grayfia stands at the center wearing her professional maid uniform, Albert Dunois seated at the head of a long table with six researchers positioned along both sides. Multiple magical instruments and technological recording devices cover the surface.

"Perfect timing," you observe while settling into a comfortable observation position. "Looks like they're just finishing preliminary setup."

Albedo moves beside you, folding her hands primly while studying the scene. "Albert brought an impressive technical team. I count three physicists, two magical theorists, and what appears to be a military technical analyst. They're taking this demonstration very seriously."

Grayfia's voice carries through the portal clearly despite the one-way observation enchantment. "Gentlemen, I appreciate your patience during the setup process. Before we begin, I should clarify that my master has instructed me to demonstrate capabilities without providing technical explanations. You're welcome to record and analyze whatever you observe, but I won't be answering questions about methodology."

Albert leans forward, his diplomatic bearing evident despite visible tension. "We understand the parameters. Please proceed whenever you're ready, Mademoiselle Grayfia."

Grayfia extends her right hand, palm upward. Demonic energy coalesces above her skin, forming a sphere of compressed magical power that radiates visible heat distortion. The researchers immediately activate recording devices, cameras whirring while magical sensors pulse with detection spells.

"First demonstration," Grayfia announces calmly. "Basic elemental manipulation at scale exceeding conventional human capabilities."

The sphere expands rapidly, growing from fist-sized to basketball dimensions in seconds. Frost patterns crystallize across its surface despite the heat distortion, contradictory elements coexisting impossibly within the same magical construct. She rotates her wrist, and the sphere splits into seven smaller orbs that orbit her hand in perfect synchronization.

One researcher frantically scribbles notes while another adjusts sensor configurations. The military analyst speaks urgently into a handheld recording device. "Energy output readings are completely inconsistent. Multiple elemental types manifesting simultaneously without observable catalyst materials."

Jibril chuckles softly from her position near the research table. "They're trying to apply scientific methodology to demonic magic. The fundamental operating principles don't translate to their technological paradigm."

"That's the point," you observe with satisfaction. "Albert needs to understand Charlotte's extraction isn't negotiable. Demonstrating capabilities his researchers can't analyze reinforces that reality."

You settle into a comfortable position near the modified portal while Grayfia continues her demonstration. The researchers frantically adjust their equipment as she manifests increasingly complex magical constructs, each one defying their technological understanding more completely than the last.

Jibril leans forward with visible amusement. "Watch how the military analyst keeps trying to apply electromagnetic theory to demonic energy manipulation. He's completely missing that the fundamental operating principles are incompatible with their scientific paradigm."

"The physicists gave up after the third demonstration," Irene observes quietly. "They're just recording data now without attempting real-time analysis. Smart decision, honestly."

Albedo folds her hands primly. "Albert brought competent specialists. They recognize when they're encountering something completely outside their expertise."

Ikaros stands near the wall, wings folded close. "The technological recording devices are capturing accurate visual data, but none of their sensors can measure the actual energy flows. They're blind to the mechanisms despite seeing the results."

Grayfia dispels her magical constructs with a casual gesture. "Gentlemen, I appreciate your thorough documentation efforts. As you've observed, the capabilities I've demonstrated operate on principles fundamentally different from your world's technological or magical frameworks."

Albert straightens in his chair, diplomatic bearing evident despite visible tension. "Mademoiselle Grayfia, your demonstration has been thoroughly recorded. Might we discuss the parameters for... Charlotte's custody transfer? My technical team has provided all the analysis they can offer."

"Of course, Monsieur Dunois." Grayfia's professional tone doesn't waver. "My master offers technology from another world in exchange for your daughter's legal custody. The specific technologies available depend on what world is chosen."

One of the physicists speaks up hesitantly. "What technological advancement level are we discussing? Near-future developments, or something more significant?"

"Depending on the world, significantly more advanced," Grayfia confirms. "My master possesses access to multiple technological paradigms from various worlds. Fusion power generation, advanced materials science, medical treatments for conditions currently considered terminal. The specific exchange depends on which worlds technology my master chooses to exchange for Charlotte."

Albert's diplomatic mask slips briefly, revealing genuine shock. "You're offering technologies that could revolutionize entire industries. That seems extraordinarily generous for custody of a single student."

"My master values Charlotte's potential," Grayfia replies smoothly. "The exchange reflects that assessment. Now, regarding the transfer logistics, do you prefer a public exchange, or would you rather handle this through discretion?"

Albert glances at his researchers, then back to Grayfia. "Discretion seem far more appropriate. A public display would create international complications I'd rather avoid."

"Understood. Then we should arrange a private exchange location where Charlotte can meet her new master without media attention."

Jibril chuckles softly from her position beside you. "Albert's trying so hard to maintain diplomatic composure while processing that his daughter is worth fusion reactor designs. The cognitive dissonance is delicious."
