The reason Ikaros had suddenly appeared in Izumi's world was, in truth, nothing more than an accident.
At this point, countless dimensions were slowly converging toward Izumi's universe.
And naturally, the world of Heaven's Lost Property was no exception.
The people living there simply had no way of noticing it.
Ikaros's situation was somewhat similar to the incident where Rin Tohsaka had once slipped through dimensions by accident. Only this time, she had been caught in a spatial storm created by the friction between two worlds.
She had been flung out of her own dimension—
And because her world itself was already being drawn toward Izumi's, she ended up falling directly onto the outer boundary of his universe.
Then gravity did the rest.
In the end, Izumi discovered her.
To put it simply—
The destination had always been Izumi's world from the very beginning.
Daedalus packed up several important devices along with a few of her Angels before leaving together with Gabriel.
Now that she had decided to go, she saw no reason to hesitate.
And naturally, the Angels she created obeyed her completely.
None of them objected to traveling to another world.
Meanwhile, Rias and Sona noticed Gabriel had already departed.
They glanced down at the countless Artificial Angels below.
Without wasting another second—
They acted.
A massive sphere of demonic power materialized above Synapse.
Then, with a casual flick of the hand, the two girls released it.
The enormous blast descended like divine judgment.
And the instant it detonated—
The floating continent was swallowed whole.
The explosion erased everything in mere moments.
When the dust finally settled, only the Master of Synapse and a handful of his closest subordinates remained alive.
They stared blankly at the ruined remains of their homeland.
"Who… were those people?!"
"Why?!"
"Why did they attack us?!"
The Master of Synapse's face twisted in fury.
He had no idea what had happened.
His kingdom had simply been destroyed without warning.
And what made things even worse—
When he tried to search for Daedalus—
She was gone.
Completely gone from this world.
That was when he finally realized it.
This disaster was no coincidence.
And then he noticed something even more terrifying.
The Rule Stone Tablets—
The very foundation that maintained the floating continent—
Had also vanished.
Without them, Synapse would eventually fall from the sky.
The realization made his expression turn deathly pale.
But that was not all.
The gate connecting Synapse to the surface world had also been sealed shut.
They could neither descend—
Nor escape.
Which meant only one thing.
They were trapped here.
Waiting for death.
"DAEDALUS!!"
The Master of Synapse roared in rage.
In his mind, she had orchestrated everything.
She had abandoned them.
No—
She had condemned them to die.
But no matter how furious he became…
There was nothing he could do.
...
Meanwhile, Gabriel had already returned to Izumi's world with Daedalus and the others.
The moment Daedalus, Nymph, and the Angels arrived—
They froze.
The magnificent city before them…
The unfamiliar laws directly imprinted into their minds…
The sheer scale of this universe…
Everything overwhelmed them.
Gabriel brought them directly to the research institute.
Izumi had naturally sensed their arrival long ago.
So he had already been waiting there.
Looking at the blue-haired Daedalus, Izumi smiled faintly.
"Welcome, Daedalus."
"From now on, this place will be your home."
Daedalus stared at him seriously.
"You're the ruler of this world?"
Izumi nodded.
Without hesitation, she immediately asked:
"Where is Ikaros?"
To Daedalus, the Angels she created were like daughters.
If Ikaros had truly ended up here by accident—
Then she needed to know whether the girl was safe.
Izumi pointed toward the laboratory behind him.
"She's inside."
"You can go in."
"My people are currently removing her emotional limiter."
The moment she heard that, Daedalus could no longer stay calm.
She rushed straight into the facility.
Until she fully understood this world, there was no way she would casually allow strangers to tamper with Ikaros.
Izumi naturally understood exactly what she was thinking.
But he didn't mind.
Instead, his gaze shifted toward a certain blonde Angel who was curiously looking around everywhere.
"Astraea, right?"
The blonde girl blinked in surprise.
"Eh? You know my name?"
"Amazing!"
Nymph instantly twitched.
"Idiot!"
"What are you saying?!"
She genuinely had no idea how to deal with this hopeless fool anymore.
But seeing that reaction only made Izumi grin wider.
Teasing idiots was always entertaining.
"So," he said casually, "want to go get something to eat with me?"
"I know a place with really good food."
The instant Astraea heard the word food—
Her eyes sparkled like stars.
"Yes! Yes yes yes!"
"Please take me with you!"
Nymph nearly wanted to bury herself underground from embarrassment.
This idiot actually agreed immediately?!
But Astraea paid her absolutely no attention.
Right now, her brain only contained one thing:
Food.
She instantly rushed over and grabbed Izumi's arm tightly.
Just as Nymph was about to protest, Izumi spoke again.
"Nymph, right?"
"From now on, think of this place as your home."
"As for me…"
"I'll take this girl to eat first."
"Someone will come arrange accommodations for you all shortly."
The moment he finished speaking—
Izumi and Astraea vanished on the spot.
Nymph opened her mouth—
But the words never came out.
Because they were already gone.
Seeing this, she sighed helplessly.
"Astraea, you idiot…"
"You got tricked the moment we arrived…"
"No, this won't do."
"When Lady Daedalus finishes her work, I'm making her improve Astraea's processing capabilities."
This girl was far too easy to fool.
One meal was enough to lure her away.
At this rate, Nymph honestly feared that one day Astraea might suddenly come home carrying a baby Angel and proudly announce:
"This is my child!"
Because with her intelligence…
That scenario genuinely felt possible.
After all—
Anyone who could be bribed away with food clearly understood absolutely nothing.
Especially since—
Nymph was completely convinced of one thing.
Izumi was definitely not a good person.
The very first thing he did after meeting them—
Was take away the easiest girl to deceive.
Nymph felt utterly exhausted.
And just as she was wondering what to do next—
A very cute little girl suddenly appeared in front of her.
