**Z-Valhalla. The Sealed District (Formerly District Z).**
**Sunday. 6:00 AM.**
The birds don't sing here. The wind doesn't blow.
This district was sealed off by Blast's barriers because the residual energy from the "Fusion" was too unstable. Reality flickers here like a dying lightbulb.
In the center of the district stands a simple house.
It isn't a palace. It isn't a dungeon.
It is a traditional Japanese house with a porch.
Sitting on the porch is an old man.
He is bald, not like Saitama, but like a monk. He has a long white beard. He wears simple robes.
He is sipping tea.
He is **The One Above All**. (Or whatever you call the conceptual capital-G God of this particular crossover mess).
Let's call him **Sensei**.
Sensei watches the sunrise. The sun is glitching—flashing between red and yellow.
"The plot threads," Sensei murmurs. "They are unraveling."
**The Visitors.**
Saitama walks down the empty street. He is wearing his pajamas and slippers.
Genos follows, carrying a trash bag. (It is Sunday trash collection day, and District Z is the dump site).
Saitama sees the old man on the porch.
"Morning," Saitama nods. "Nice weather if you ignore the glitching sun."
Sensei puts down his tea.
"Saitama. I have been waiting for you."
Saitama stops.
"For me? Did I forget to return a library book? I swear I put it in the drop box."
"No." Sensei stands up. He is small, frail looking. But his shadow stretches across the entire district.
"I am the Administrator of this Reality. The one Blast works for. The one who keeps the ink from spilling."
Saitama scratches his stomach. "Okay. And?"
"This merger," Sensei gestures to the world. "It cannot hold. The file size is too big. Z-City and Valhalla must separate. Or both will crash."
Saitama blinks. "Crash? Like a computer?"
"Yes. Blue Screen of Death for the universe."
**The Choice.**
Sensei steps off the porch. The world ripples around his feet.
"You are the Anchor, Saitama. Your strength broke the barrier, and your indifference holds it together. To separate the worlds, the Anchor must let go."
"Let go of what?"
"Your apartment," Sensei says gently. "Your new friends. The curry nights. The discount udon shop."
Saitama freezes.
"But... I just got the Black Card. We share custody."
"If you hold on," Sensei warns, "Entropy consumes everything. No more sales. No more Mondays. Just void."
Genos steps forward. "Master. Analysis confirms his statement. Structural integrity of the meta-verse is at 4%."
Saitama looks at Genos. He looks back at the city skyline—where Odin's castle merges with the Shopping Mall.
He remembers Thor washing dishes.
He remembers Satan's apron.
He remembers King's high score.
"So I have to leave?" Saitama asks.
"You have to choose," Sensei corrects. "Return to your world of monsters. Let them return to their world of gods. Reset the status quo."
Saitama looks at his fist.
The fist that solved every problem.
Can he punch a Reboot?
"Is there a third option?" Saitama asks.
Sensei smiles. "There is always a third option. But it requires effort. Infinite effort."
**The Third Option.**
"Punch it," Saitama says. "Punch the logic."
Sensei nods. "If you strike the Core of the Merge with enough force to generate a **Canon Welding Event**, you can stabilize the crossover permanently. But..."
Sensei points to the glitching sun.
"The Core is in the sun. And it burns with the heat of a trillion narrative arcs."
"Sun, huh?" Saitama looks up. "It's a bit bright."
"Genos," Saitama says. "Take the trash to the designated bin. I'll be back."
"Master?" Genos senses the intent. "You intend to punch the sun?"
"Just a quick tap."
**The Departure.**
Saitama crouches.
The ground of District Z atomizes under the pressure of his preparation.
He looks at Sensei.
"Hey, old man. If this works... do I get a rent reduction?"
Sensei laughs. "I am God. I do not control landlords."
Saitama sighs. "Figured."
He jumps.
*BOOM.*
He leaves the atmosphere in a millisecond.
He passes the moon.
He flies towards the glitching sun.
**The Welding.**
Saitama enters the solar corona.
It's hot. Hotter than the Plankton King.
His pajamas burn away instantly (censored by conveniently placed solar flares).
He sees the Core—a jagged scar of blue static in the center of the star.
"Serious Move," Saitama whispers in the vacuum.
He pulls his fist back.
He pours everything into it. Not anger. Not boredom.
But the desire to keep his friends. To keep the curry. To keep the cheap noodles.
**Serious Series: Serious Welding Punch.**
He strikes the Core.
The impact doesn't destroy. It *fuses*.
It forces the two realities to shake hands. To accept each other.
Logic bends. The Narrative yields.
*FLASH.*
A blinding white light engulfs the solar system.
***
**The Aftermath.**
Saitama lands back on the street.
He is smoking. His pajamas are gone. He is holding a piece of debris for modesty.
The sky clears.
The sun is stable yellow.
The glitching buildings solidify. The merger is permanent.
Valhalla is no longer a dimension; it is officially Z-City District 13.
Sensei is gone.
On the porch sits a basket.
Inside:
* A new pair of pajamas.
* A coupon for 50% off at the IKEA cafeteria.
* A note: *"Welcome to the Canon."*
Genos runs up, holding a towel. "Master! You have exposed your chassis!"
Saitama grabs the towel. "Yeah, yeah. Did you dump the trash?"
"Affirmative. The mission was successful."
Saitama looks at the stable, weird, hybrid city.
A dragon flies overhead, chased by a police helicopter.
Thor walks by, eating an ice cream cone with Metal Bat.
King is gaming with Loki in the park.
"It worked," Saitama smiles.
"Let's go home, Genos. I think Satan made pancakes."
"Yes, Master."
They walk into the sunrise of a new, stable, ridiculous world.
The strongest hero.
And his new, godly neighborhood.
