Bronya stared at the private red packet.
A single Heavy Armor Bunny.
Not just a motorcycle—
Not just a mech—
Not just a fusion-powered technological miracle—
It was a symbol.
A symbol that Takumi trusted her enough to give her something worth 3,000 points, for free.
In the chat, everyone waited with bated breath.
Sagiri:
"Bronya-san… you're super lucky…"
Fujiwara Chika:
"Takumi is giving out Legendary SSR summons again!!"
"I want a Bunny too!! Σ(っ°Д°;)っ"
Akeno:
"Takumi-kun spoils us too much."
Zhongli:
"Knowledge in exchange for knowledge. A fair trade."
Himeko:
"A Bunny, huh? Yours looks way cooler than the one I knew."
Bronya finally spoke.
Bronya:
"…Takumi. I will repay this."
"Properly."
Takumi smiled.
He hadn't doubted her for even a moment.
Bronya Accepts, Civilization Reacts
Bronya pressed the red envelope.
The Heavy Armor Bunny materialized in her own world—sleek, matte-black, glowing with pale-blue conduits and a reactor core that hummed like a heartbeat. The AI blinked to life.
[HAB-01 Activated]
"Hello, Master. Ready to synchronize operational parameters?"
Bronya felt her breath catch.
Her world had prototypes—underfunded, inefficient, incomplete.
This one was…
Perfect.
The onboard display recognized her vitals, uploaded her preferences, and placed itself into a defensive standby mode just as her security team burst into her garage.
"Miss Bronya! What was that light?!"
"Is it an attack?!"
"Stand back!"
"We'll call the military!"
Bronya waved them away like bothersome pigeons.
"Relax. It's mine."
They stared at the Bunny—transformable mech, fusion engine, weapons labeled with "Do Not Aim at Civilians."
One guard fainted.
Another guard whispered, "Miss… Miss Bronya… did you… join a cult?"
Bronya pinched her nose.
"No. I joined a professional group chat."
Back in Takumi's World…
Takumi laid on the soft grass beside the Great Library-Tree, staring at the plaza projections updating in real-time.
Bronya had already connected the Bunny's camera to the chat.
Fujiwara Chika:
"Cool!! COOL!!"
Sagiri:
"It moves! It walks! Bronya-san please make it wave!"
Bronya (calmly typing):
"HAB-01, wave."
The colossal mech raised a steel-clad arm and waved politely at the camera.
Chika:
"HAB-chan is so polite!!"
Even Eu sent a single dot of approval:
Eu: "."
For Eu, that was basically a scream of excitement.
Takumi laughed softly.
A slice-of-life scene among gods, devils, immortals, and a CEO with a mech.
Exactly what he needed after hours of city planning.
The SEEDs quickly appeared, rolling closer to Takumi.
SEED-1:
"Observation: Social atmosphere improved."
"Leader mood: positive."
SEED-3:
"Recommend: Assign 'Honkai-Relation Mitigation' as a cultural research topic."
Takumi:
"You want to start cultural studies?"
SEED-1 nodded.
"Civilization development includes emotional understanding."
"Chat group members exhibit unpredictable positive reactions."
"We must learn."
Takumi patted its metal shell.
"Good idea."
Civilization wasn't just tech.
It was feelings, relationships, inside jokes.
And Bronya had just added a new dynamic—
Corporate efficiency meets chaotic multiverse friendship.
The Treaty Proposal
Bronya reappeared in the group.
Bronya:
"Takumi. I'll provide you with everything."
Takumi:
"Everything?"
Bronya:
"All technological research from my world. All blueprints. Engineering theory. Software. Materials science. Fusion reactor math. AI ethics. Network architecture. Military defense frameworks."
"Even prototype weapon designs."
Silence swept across the group.
Even Himeko paused mid-coffee sip.
Zhongli leaned forward.
Fujiwara Chika typed only one word:
"W O W."
Takumi blinked.
That was…
Essentially the entire technological tree of a parallel Earth.
"Are you sure?" Takumi asked carefully.
"If you give away that much tech, your world might fall behind. Or destabilize."
Bronya shook her head.
Bronya:
"Takumi. The moment this chat group appeared, all our worlds were already connected."
"Knowledge cannot be contained forever."
"But I want to choose how we share it."
Then she delivered the most Bronya line ever:
"In business terms: I want to be an early investor."
Ah.
There it was.
The CEO.
The monarch of logic.
Takumi couldn't help but grin.
Akeno:
"That's a very Bronya thing to say."
Himeko:
"You're as ambitious as ever."
Zhongli:
"A wise move. Foundations built early shape the future."
Bronya ignored them.
Bronya:
"Takumi, I propose a treaty."
"The 'First Cross-Dimensional Technology Transfer Agreement.'"
Takumi sat up straighter.
"Explain."
Bronya typed:
"My world will provide you with full technological data."
"In exchange, your civilization will give us future access to Honkai-Energy-based infrastructure."
Sagiri:
"W-Wait, is that allowed??"
Fujiwara Chika:
"This is like… interdimensional diplomacy?!?"
Bronya nodded.
Bronya:
"We establish a partnership."
"Mutual growth. Shared prosperity."
Takumi closed his eyes.
Inside him, the Cocoon pulsed.
Not greedily.
Not violently.
But with interest.
Knowledge for knowledge.
Progress for progress.
Civilization development.
The more his world advanced,
the stronger he became.
But also…
The more he could protect people—
like Sagiri, like Chika, like Eu.
Like the future immigrants.
Takumi's voice softened.
"Bronya… are you sure? If you give everything, that means trusting me with the potential to surpass your world."
Bronya:
"Takumi."
"You're the only one here with a stable head."
"You could destroy planets, bend cities, rewrite matter."
"Yet you build farms and robots and schools."
Her tone warmed just slightly.
"I trust your leadership."
The group went silent.
Even the SEEDs froze their logs.
Takumi's mind trembled.
Not from pride.
From responsibility.
The Cocoon whispered that he could remake the world in his image.
But Bronya saw someone who built—not conquered.
He inhaled deeply.
"Then I… accept the treaty."
The plaza's lights flickered.
A moment of light reality distortion rippled—
not destructive, but symbolic.
A Contract was Formed.
The First Download
Bronya uploaded the first package.
[File Uploaded: WorldScienceArchive.v1 (1.2 TB)]
Takumi barely blinked.
His mind—connected to the Cocoon—
swallowed the data whole.
Blueprints.
Research papers.
30 years of innovations.
AI developments.
Fusion reactor schematics.
Quantum encryption models.
Manufacturing protocols.
His brain lit up like fireworks.
He opened his eyes.
The world below him changed.
Not physically—
Not yet—
But conceptually.
He saw new possibilities.
Electric grids.
Smart cities.
Nanofactories.
Autonomous medical systems.
Quantum material printers.
Mass-producible clean energy.
His heart pounded.
But not from power.
From excitement.
"Bronya," he whispered.
"This is… amazing."
Bronya simply typed:
"Phase 1 complete."
Zhongli bowed slightly toward the projection.
Himeko toasted with her coffee mug.
Sagiri quietly saved the files—
hoping she could learn something.
Chika wondered if she could use the tech to automate homework.
Eu just typed:
"Good."
Reality Distortion Moment
As Takumi processed technology…
His consciousness expanded.
The Cocoon synced with human innovation.
Something shifted.
The sky above the Library-Tree shimmered—
like circuitry overlaying the stars.
Takumi felt the laws of physics around him hum.
His Herrscher Authority integrated new forms of engineering, new logic models, new energy architectures.
His body lightly glowed.
SEED-1 panicked.
SEED-1:
"Leader is ascending??? Should I fetch grounding protocols?!"
Takumi held up a hand.
"No, no—just learning."
He absorbed the tech.
He didn't lose himself.
He didn't drown.
He chose restraint.
And the distortion faded.
The Chat Group Reacts
Fujiwara Chika:
"Takumi??? Did you evolve???"
Akeno:
"He looks… shinier."
Sagiri:
"Takumi-nii's hair sparkled…"
Himeko:
"That's normal. He does that after big data bites."
Zhongli:
"Indeed."
Takumi:
"I'm fine. Just… upgrading."
Bronya:
"Good. Phase 2 coming tomorrow."
Takumi nearly choked.
"There's a Phase 2!?"
Bronya:
"Of course."
"Business works in phases."
Chika:
"Bronya is scarier than a Herrscher…"
Sagiri:
"Businesswoman OP…"
Takumi laughed.
Out loud.
This—
this multiverse family—
was exactly what he needed.
The Next Day—Civilization Level Up
Takumi woke up with a plan.
A real one.
He summoned the SEEDs.
"From today onward," he said, "we launch the First Interdimensional Civilization Project."
The SEEDs cheered through text notifications.
Bronya uploaded Phase 2—computer science.
Zhongli began creating immortal-era cultural modules.
Sagiri began learning talisman tech.
Chika practiced water-flow agriculture.
Akeno studied Honkai-assisted magic amplification.
Eu quietly mastered containment spells.
And Takumi…
Takumi began designing the first Interdimensional Academy.
A place where immigrants from all worlds could learn, share, and grow.
A seed for the future.
A foundation.
Civilization had begun.
