Rita couldn't help but smile wryly when she saw Durandal agree to Izumi's invitation so readily.
Izumi, on the other hand, looked thoroughly pleased.
"So," he turned his gaze toward her, "what about you?"
Rita let out a soft sigh.
"Since Lady Durandal has already agreed… I suppose I have no objections."
She lowered her head slightly and performed a perfect maid curtsy.
"Izumi-sama, I look forward to working under you."
That elegant gesture alone was enough to prove her professionalism.
Izumi grinned.
"Good. Then—Grayfia."
At his call, a figure clad in blue and white appeared beside him as if stepping out from thin air.
She bowed gracefully.
"I await your command."
Grayfia Lucifuge—the ultimate maid of the Underworld.
She turned toward Rita and offered a refined greeting.
"Rita-sama, it is a pleasure to meet you. I am Grayfia, a devil by race and Izumi-sama's personal maid. I look forward to working with you."
Rita's eyes flickered slightly.
As a fellow maid, she immediately recognized it—this woman was on an entirely different level.
A quiet sense of mutual respect formed between them.
Grayfia, meanwhile, already understood Izumi's intentions perfectly.
There was no need to ask.
With that, matters were settled.
Izumi had gained a new maid.
Meanwhile, the people from the Honkai world began exploring this vast new reality.
The young girls who had long grown bored in this place quickly became enthusiastic guides, leading the newcomers across different regions.
As for Izumi—
he summoned Jibril.
Durandal was officially handed over as their superior, and Izumi granted her a new power.
The Anchor of the Stars.
A power that made her transcend her previous limits.
Rita wasn't left out either.
Izumi granted her abilities as well—lightning manipulation, alongside the powers reminiscent of Lost Rosemarie and Argent Knight: Artemis.
His intention was simple.
He was recreating them into their strongest forms.
After all, with so many worlds merged, Izumi now possessed an overwhelming arsenal of powers.
Granting abilities like this?
It was effortless.
Once everything was arranged, Izumi didn't rush off to conquer another world.
Instead, he stayed.
Spending his days leisurely with Cecilia, strolling through his ever-expanding domain.
From atop the colossal world tree, Izumi gazed at everything he had built.
His eyes narrowed slightly.
"…Feels like something's missing."
Then—
he snapped his fingers.
Snap.
At that exact moment—
every single being across every world stopped.
They all looked up.
And Izumi spoke.
"I can tell you've all been holding back."
A faint smile spread across his lips.
"So… let's play."
"The greatest war this world has ever seen."
Silence.
Then—
his voice echoed again.
"You may fight alone or form teams."
"As long as you register for this competition…"
"I will grant the winner any wish."
"Power. Items. Even godhood."
"Everything is possible."
A heartbeat passed.
Then—
the world exploded into chaos.
"OOOOOOOOOOOOOO!!!"
Cheers, roars, madness.
Everyone lost their minds.
This reward… was irresistible.
For those who had long been suppressed by the rules—
this was freedom.
True battle.
Unrestrained.
Izumi continued calmly.
"The rules are simple."
"Defeat your opponent—advance."
"Win again—advance again."
"Until only one remains."
"That person…"
"…will stand before me."
More rules followed.
Each world would act as its own region.
Victors from each world would rise—
and then face off on a final stage.
A grand arena.
Broadcast to the entire multiverse.
Moments later—
colossal arenas manifested across every world.
- Orario in the DanMachi world
- The chaotic lands of KonoSuba
- The recovering Honkai Earth
- The Holy Grail battlefields
- Academy City
Each one now housed a massive battlefield capable of holding millions.
When Izumi returned to the World Tree—
a group of small figures rushed toward him.
"Onii-chan! Onii-chan!!"
Enju Aihara looked up at him with sparkling eyes.
"Can we join too?"
Izumi sighed helplessly.
"…Better not."
"Eh?!"
"You've got more important work."
He patted her head.
"I need you guys to help maintain order."
"There are way too many people. If things get out of control, it'll be a mess."
Enju puffed her cheeks in disappointment.
But soon, she nodded with determination.
"…Okay! We'll do it!"
After settling that, Izumi moved again.
This time, he summoned his strategists.
- Senju Kayo
- Sora
- Aiba Asagi
Together, they refined the system.
The final format became clear:
Each world would produce its strongest representatives.
And those champions…
would lead their worlds in the ultimate battle.
Five major worlds stood at the center:
- DanMachi
- KonoSuba
- Honkai
- Fate
- Toaru
Izumi crossed his arms, thinking.
"…Still feels like it needs more."
Then he smirked.
He sent a message.
To another world.
"To Rias… ask your brother."
"See if he wants to join the fun."
Because in Izumi's world—
the more chaotic it became…
the more entertaining it was.
