Avrora had absolutely no idea she had been reduced to a convenient tool.
Following Izumi's orders, Himejima Akeno, Shinra Tsubaki, and the others also rushed into battle.
Avrora didn't even need Izumi to explain anything; she already understood what her new mission was.
Beat all of them down, collect her reward, and demand food from Izumi afterward.
With that sacred goal in mind, she summoned more familiars.
She possessed terrifying power, but almost no battle experience.
So for now, she relied on numbers to overwhelm Rias and the others.
Her familiars acted with their own instincts, but were ultimately guided by her command.
Once Akeno and Tsubaki joined the fray, Sona immediately retreated a few meters, quickly reorganizing their formation.
Everyone here understood very clearly just who that dumb little loli was.
The Fourth Primogenitor. A demon lord-class existence.
Even if she fought like a newborn deer, her strength alone could one-shot all of them if she ever landed a direct blow.
Dodging was easy enough for now.
But if she hit them even once, it would be instant KO.
Which meant cooperation was no longer optional—
it was a matter of survival.
Watching the chaotic airborne clash, Izumi nodded in deep satisfaction.
He called out lazily, smirking:
"Do your best, Avrora.
If you want a nice big dinner, knock them all down.
If not—enjoy sleeping on an empty stomach tonight."
He gathered Megumi Kato and a few others, walking to a clear area where Rin Tohsaka and the rest were waiting.
"Rin, I'm counting on you.
Teach Megumi and Koneko the basics of reinforcement magecraft."
"Illya, I want you to instruct Asia and Eriri.
Give them some standard Einzbern magecraft.
Sakura, if you're interested, you can learn too."
Nobody objected to the arrangement.
Once everything was delegated, Izumi happily collapsed onto a beach chair with Ophis curled beside him.
The Infinite Dragon God silently watched battle unfold, her expression unchanged as always.
Izumi, however, finally had a moment to deal with his spoils.
Silently, he opened the system and tossed in several stolen treasures one by one.
[You have obtained: Complete Guide to Space Manipulation Magic]
[You have obtained: Passive Skill – Golden Rule]
[You have obtained: Vimana]
[You have obtained: Stone of Space]
[You have obtained: Gate of Traversal]
[You have obtained: Honkai Core – Herrscher of the Void]
[You have obtained: Gift – Object Transference]
…
Staring at the haul, Izumi blinked.
"Not bad. Nothing outrageously broken this time."
Without hesitation, he began using almost everything.
The Gift Object Transference was ignored—
he already had substitution magic. Redundant.
The Herrscher of the Void Core, however…
That was worth the trouble.
Izumi had a soft spot for the powers of the Void Herrscher.
Spatial manipulation. Imaginary space. Subspace spears. Space-time lock. Space-time explosion. Distortion.
With this, he could abuse space itself.
Even without Honkai beasts or collapse energy in this world, he could still open black holes and summon giant cannons of destruction.
Great fun.
Especially the imaginary space—almost identical to his personal miniature world.
And possibly compatible.
His eyes lit up.
Without hesitation, he activated it all.
Golden Rule triggered instantly, but being passive, he felt no immediate change.
But when the Void Herrscher core fused with his being—
Izumi's control over space skyrocketed.
Space manipulation. Imaginary matter creation.
Subspace blades capable of shearing dimensions.
Personal phase-shift and intangibility.
Spatial barriers.
If anyone else received this, they'd instantly become S+ tier, minimum.
Naturally, Izumi kept it for himself.
Techniques and applications flooded his mind, countless possibilities unfolding.
He laughed softly.
He was one step closer.
SSS-Rank, the Four-Digit Level of Little Garden, was within reach.
And that wasn't the end.
Out in the multiverse, even that level was merely mid-tier.
He still had a long climb ahead.
Ophis, as always, noticed instantly.
"You grew stronger again."
Izumi nodded.
"A bit.
Soon, I'll be able to reach SSS-Rank, just like you."
The idea alone filled him with excitement.
With the new core, his power had risen dramatically.
He closed his eyes, merging imaginary space with his miniature world.
The internal realm expanded rapidly.
In mere moments, its size had doubled.
The simulated star-forge began synchronizing with greater speed.
Feeling the vast surge in power, Izumi gave a satisfied exhale.
Next, he looked over the remaining items.
Vimana—
Gilgamesh's beloved divine flying craft.
Ignoring physics, moving at absurd speeds.
Armed with advanced weapons.
Even stocked with ancient nuclear warheads.
Perfect.
As for the Gate of Traversal, he opened its description.
[Gate of Traversal: A gateway allowing travel to other worlds. Destination is random.]
"…So it's a high-tier version of the World Locator."
Fantastic.
Another key to future multiverse trips.
The Stone of Space, meanwhile, was obvious.
A crystal holding spatial attributes.
Ideal material for creating magical girl transformation devices.
Which was hilarious.
But also useful.
He tossed it aside for now.
He hadn't even finished the Time Stone yet; he didn't need another project.
Next, he examined the Complete Guide to Space Magic.
Minamiya Natsuki's spellcraft.
Perfect for Sakura, whose attribute was Void—
space affinity.
Let her master it; he had better tools now.
Magic could never compare to authority.
Last, Gift: Object Transference.
Kurousagi's ability - capable of moving objects along extended vectors, or forcibly stealing armaments and gifts from others.
A strong ability.
Just not for him.
He set it aside for someone else.
Izumi stretched lazily.
Power, treasures, new worlds, new tools.
Life was good.
Meanwhile, Avrora continued unleashing familiars with terrifying enthusiasm—
all because she'd been promised dinner, goldfish, and lollipops.
The Fourth Primogenitor.
Demon lord-class existence.
Weaponized by food.
Truly, a cosmic tragedy.
