The moment Izumi mentioned that peaceful days were approaching, he had already figured it out.
This fellow from another world intended to challenge Artosh.
With his intelligence, it wasn't difficult for him to guess Izumi's plan.
Hearing his words, Izumi smiled.
"You're pretty good."
"Keep working hard."
After saying that, Izumi left with Mash and the others, departing from that place and returning directly to his own world.
If he wanted to challenge Artosh, some preparation was still necessary.
After all, Artosh had a considerable number of Flügel under his command.
Izumi needed to gather an army capable of matching them.
When Jibril and Schwi entered Izumi's world for the first time, both of them were stunned.
"…Is this another world?"
Schwi immediately began running calculations.
"Connection to network unit interrupted."
"Analyzing cause."
"Unknown signal detected. Beginning analysis."
"…."
Before she could continue, Izumi spoke.
"That's enough, Schwi."
"This is my world. There's no need to analyze it."
After saying that, Izumi snapped his fingers.
In an instant, the entire group vanished from their spot.
The next moment, they appeared atop an enormous World Tree-like giant tree.
The lush emerald scenery was something neither of them had ever seen before.
When the others noticed Izumi had returned, they quickly gathered around him.
They began asking about the world he had visited, while also casting curious glances at Jibril and Schwi.
Especially Gabriel, who looked at Jibril with surprise.
"Izumi… is she an angel?"
Izumi shook his head.
"No, she isn't."
"She's a Flügel, a race created purely for warfare and slaughter."
"Have everyone gather. Let's hold a short meeting, then we'll go attack the final boss of that world."
As he said this, excitement appeared on Izumi's face.
The moment the others heard his words, their eyes lit up.
Another battle?
Thinking about it made them eager.
Everyone immediately began calling the others over.
At that moment, Jibril spoke up.
"Eh? Are we already going to fight Lord Artosh?"
She sounded extremely excited.
Oh my, this was getting interesting—she had just switched sides, and now she would immediately be fighting her former master.
Izumi nodded.
"That's right."
"Don't tell me you can't bring yourself to fight?"
However, Izumi had underestimated Jibril.
Her face was practically screaming mischief.
"Hehe, I don't mind at all."
"I've wanted to punch Azriel for a long time now."
Just mentioning that name filled her face with dissatisfaction.
Now that an opportunity had appeared, she definitely wouldn't miss it.
Still, there was something she needed to say.
Jibril looked at Izumi and hesitated for a moment before speaking.
"If we end up fighting the Flügel… could you avoid killing them?"
Even though she had already left the Flügel, she still couldn't bring herself to harm her sisters.
If possible, she hoped Izumi would spare them.
Izumi nodded.
"That's fine."
"We'll just beat them until they turn into little girls and capture them."
For a combat force like the Flügel, Izumi certainly wouldn't let them go.
His gaze was already set upon the multiverse.
If he wanted to continuously strengthen himself, he needed more forces capable of fighting for him.
If he encountered another world like the EXE world, their combat power would become extremely valuable.
After all, it wouldn't be practical for Izumi to handle everything alone.
Even though he had the strength, it would still be exhausting.
After hearing Izumi's answer, Jibril immediately smiled brightly.
She hugged Izumi and rubbed against him happily.
"Then thank you, Master~!"
This time, she called him "Master" with genuine sincerity.
Seeing Jibril like this, Izumi couldn't help but think to himself.
He reached out and lightly pinched her wing.
"Aren't you going to show some gratitude?"
Jibril froze.
Her face instantly turned bright red.
She couldn't understand how Izumi knew about that weakness!
"S-Stop…!"
"Please stop!"
…
Seeing her flustered reaction, Izumi finally released her.
The people watching nearby all wore strange expressions.
After teasing Jibril for a moment, Izumi put away his smile and quietly waited.
Not long after, the others arrived one by one.
Gaia and Alaya also appeared.
Izumi then explained the situation in that world.
They would fight Artosh, break the Spirit Corridor, seize the Star Cup, become the master of that world, and finally merge that world into their own.
Gaia and Alaya already understood Izumi's plan quite well.
The world of No Game No Life was considered a relatively high-level world.
As the will of Izumi's world, they had no objections to merging another world.
After all, it would benefit them as well.
And according to Izumi, once the Star Cup was obtained, they could gain full authority over that world.
Naturally, this made them very excited.
It was essentially the same as gaining the power of an entire world for free.
After discussing it, everyone agreed without objection.
Soon after, Izumi prepared a warship.
With a full ship of S+ rank fighters, they set off in a grand formation.
Rias Gremory, Sona Sitri, Kanase Kanon, and many others were among them.
They hadn't been able to participate in the battle in the EXE world before.
But this time, they absolutely wouldn't miss it.
Artosh would naturally be handled by Izumi.
The Flügel, on the other hand, would be left to Rias and the others.
At the same time, Izumi brought Avrora and Ophis with him.
They were there to prevent any other gods from interfering.
Izumi knew very well that in that world, the gods who created the various races still existed.
Whether it was Kainas, who created the Elves, or Okun, who created the Dwarves—
They were all still alive.
After all, among the Sixteen Races, the first-ranked species was the Old Deus.
No one knew how many gods existed in that world.
These gods were born from the very concepts of the planet itself.
How many such deities could a single world possess?
That was completely unknown.
Even the original story had never clarified it.
Just considering how many races existed in that world—how many gods had created them?
Although Artosh had slain many gods and even absorbed their Divine Cores, how many truly survived?
How many were hiding in the shadows?
No one could say for sure.
In any case, bringing them along was the safest option.
What Izumi feared most was fighting all the way to the Star Cup, only for a group of hidden gods to suddenly appear and interfere.
That was the last thing he wanted.
So not only did he bring Avrora and Ophis, he also summoned Est.
Once all preparations were complete, Izumi tore open space itself.
And once again, he headed toward the world of No Game No Life.
