Rias Gremory's demonic power erupted outward.
At that moment, the full might of her SSS-Class strength was unleashed without restraint.
After spending so many years by Izumi's side, her power had long since surpassed ordinary limits.
Of course, if she wished to go even further, that would be impossible without Izumi's help.
Still—
SSS-Class was already more than enough.
It was power comparable to the Four-Digit realm.
The moment Rias prepared to attack, Sona Sitri adjusted her glasses as an icy wave of magic burst from her body as well.
In the next instant—
The two devil heiresses attacked simultaneously.
Countless magic circles spread across the skies above Synapse.
A rain of destructive crimson blasts and freezing blue artillery poured downward upon the Angeloids below.
Gabriel watched the battlefield unfold without the slightest trace of pity.
She might have been an angel—
But she was no saint.
As she observed the synthetic angels below, her eyes suddenly landed on a blue-haired woman.
"…Daedalus."
"So that must be her."
The moment she finished speaking, Gabriel vanished.
When she reappeared, she was already standing directly before Daedalus.
The reason Gabriel was so certain of her identity was simple—
The two Angeloids standing behind her.
Those two resembled Ikaros far too closely.
Unlike the mass-produced Angeloids flying around in identical uniforms and standardized equipment, these three were clearly different.
And combined with Izumi's warning before they left—
Gabriel had immediately realized who she was looking at.
...
At the same time, Daedalus herself was utterly bewildered.
Synapse had suddenly come under attack, and she had been preparing to flee with her two Angeloids.
But before she could escape—
An angel unlike anything she had ever seen appeared before her.
Daedalus stared blankly at Gabriel.
In that moment, she was genuinely shocked.
This woman…
She was what a true angel should look like.
Whether it was her presence, her aura, or the overwhelming holy power radiating from her body—
Gabriel looked like the genuine article.
Compared to her, Daedalus suddenly felt as though all of her own creations were crude imitations.
Gabriel gave a polite bow first, clearly showing she meant no hostility, before speaking.
"You are Miss Daedalus, correct?"
Daedalus frowned slightly.
"…Who are you?"
Although Gabriel carried no malice, Daedalus wasn't foolish enough to trust a stranger immediately.
Meanwhile, the blonde Angeloid standing behind her suddenly lit up with excitement.
"Wow~! You're so pretty!"
"Are you an angel too?"
The innocent reaction instantly caused the smaller Angeloid beside her to bury her face in her hands.
"Astraea, you're embarrassing!!"
Daedalus herself immediately developed a headache.
At that moment, she deeply regretted ever creating this idiot.
Couldn't she at least be cautious during a situation like this?
Astraea possessed overwhelming combat ability and emotional output—
But her calculation capacity was practically zero.
In other words—
She was an absolute airhead.
The person standing before them might very well have been an enemy, yet Astraea was casually complimenting her appearance.
This girl was beyond saving.
Honestly, if a fight broke out—
She might actually defect halfway through.
…Yeah.
That genuinely seemed possible.
Gabriel blinked in surprise before laughing softly.
"What a cute child."
She then introduced herself gracefully.
"My name is Gabriel."
"I come from another world."
Then her smile deepened slightly.
"Miss Daedalus."
"Please come with us."
"Ikaros is currently in our world."
The moment Daedalus heard that name, her pupils shrank violently.
"…Ikaros?"
"Wasn't she sealed away after disappearing from prison?"
"She ended up in another world?"
The people of Synapse had feared Ikaros's power so much that they had imprisoned and sealed her away completely.
Yet not long ago—
She had suddenly vanished.
And now someone from another world had come looking for her.
At that moment, Daedalus realized just how serious the situation had become.
She didn't believe for even a second that Synapse possessed the power to oppose people capable of traveling between worlds.
To them, it would be like peasants carrying farming tools trying to fight soldiers armed with assault rifles.
There was no comparison.
She glanced toward the distant battlefield.
Rias and Sona were utterly crushing the defending Angeloids.
The answer was obvious.
After a brief silence, Daedalus finally spoke.
"I'm willing to go with you."
"But can you tell me why?"
She truly couldn't understand it.
Why would someone from another world specifically come searching for her?
It made no sense.
Had her reputation somehow spread beyond dimensions?
That was absurd.
Gabriel smiled gently.
"It's nothing particularly secret."
"Izumi-sama took interest in your scientific talents."
"That's why he sent me here."
Her smile widened ever so slightly.
"If Izumi-sama's power weren't so overwhelming…"
"And if entering this world wouldn't risk destroying it outright…"
"He probably would have come personally."
The moment Daedalus heard those words, silence filled the air.
That was terrifying.
A being so powerful that merely entering a world could destroy it—
That was beyond anything they could possibly resist.
After taking a deep breath, Daedalus nodded seriously.
"…Very well."
"Please lead the way."
"I'll go with you."
Gabriel smiled warmly.
Then she turned toward Nymph and Astraea.
"In that case, please bring your Angeloids with you as well."
"From now on, all of you will live in our world."
"Oh, and one more thing."
She casually added:
"Your world is already moving toward ours."
"It probably won't be long before the two worlds fully merge together."
"So there's no need to worry too much."
"You're simply arriving a little earlier than everyone else."
Gabriel paused briefly before smiling proudly.
"After all…"
"Our world is now the center of the endless multiverse."
Daedalus froze in complete shock.
Beside her, Nymph looked equally stunned.
The center… of endless worlds?
What kind of terrifying place was that?
And more importantly—
Why had Ikaros ended up there in the first place?
