In an apartment there a boy was writing a story on the app and listening to the song Nightglow. He are having difficulty continuing this story, the hardest thing is to write about the war between the entire Marvel multiverse and his own Outer God creation.
The boy: "It's so troublesome. Sigh, why am I even thinking about writing about this war?"
???:"Then just leave it alone. There's no need for you to bother."
The boy: "That's right, Riza. I just need to delete it. But I haven't written a chapter in months.
Riza: "But now you have a new plan." She smiled while pressing herself against his back, her breasts touched the boy as he turned around and looked at her eyes.
The boy: "you know that I don't feel anything from you right my creation, my Outer God."
Riza:" As I thought My Creator, what will you do now create another chapter or reset.
The boy:" Now I think I will write a next chapter but not the war anymore but a new one. You will travel to other narratives to fix it and spread your name through them. Let them know about the Outer God, The embodiment of Chaos itself, the Nightmare, The End."
Riza: "Hahahaha finally you're back. I will wait for your chapter then I will let them know what Chaos is. Bye my true self." She disappeared leaving behind a small red blood start.
The boy:" now let begin."
The boy closes his eyes then lifts his hand and writes in the air soon the words begin to combine into a paragraph, then into a completed chapter page. He lightly pressed the post button and sat down on the chair. He smiled and looked at the city before him.
In Marvel
The reality of the war begins to crack, it begins to spread and covers all entities and includes the dimension in which Riza and her family live. After a flash of white light everything disappeared. Everything Riza's army had done was gone. Even the One Above All doesn't remember Riza's declaration of war. Everything is deleted.

3rd POV — Kamen Rider Zi-O World
The streets of Japan trembled as the massive Time Mazine stomped forward, its metal body gleaming beneath the afternoon sun. Sougo Tokiwa ran with desperation, his breaths ragged, his legs pumping as fast as they could. Behind him, the towering machine raised its arm cannons, locking onto the boy.
"Why is this thing chasing me!?" Sougo shouted, diving into an alley just as an energy blast tore apart the road where he stood moments earlier.
From the cockpit of the Time Mazine, Geiz Myokoin glared. His eyes burned with the resolve of someone who knew the horrors of the future.
"That boy… Tokiwa Sougo. You can never become Zi-O! I won't let the Demon King of Time be born!"
The machine raised its weapon again—when suddenly—
The sky cracked.
A blood-red fissure spread across reality itself, tearing through the blue heavens like shattered glass. The Time Mazine froze, Geiz shielding his eyes from the overwhelming light. Sougo stumbled, looking upward in awe and terror.
Out of the crack, a woman descended slowly, as if the universe itself bent to allow her passage. Her long purple hair rippled like shadows in the void, and her crimson eyes gleamed with madness and elegance. Black tendrils of chaotic energy wrapped around her, forming the shape of a Rider Belt unlike any seen before.
Riza had arrived.
The Outer God of Chaos smiled, her lips curling into something both beautiful and motherly while looking at Sougo.
Sougo whispered, "W-who… who is that…?"
Her voice echoed across space and time, resonating in the minds of all who could perceive her.
Riza: "This world calls me here. A Rider of Chaos… and perhaps, a spectator to your fate, Sougo Tokiwa - kun. Ara Ara what do we have here."
The crimson tendrils solidified into a Chaos Driver, a belt engraved with shifting runes that seemed alive. From the void, a blood-red Ridewatch materialized, its face displaying a broken infinity symbol.
With a graceful motion, Riza placed it into her Driver.
"CHAOS!"
The belt screamed as energy exploded outward.
She twisted it—
"Henshin."
A vortex of shadows engulfed her, forming Kamen Rider Chaos. Her armor was jagged black with crimson glowing veins, her helmet crowned with spiraling horns resembling her Outer God form. The visor gleamed like a predator's eye, pulsating with unstable energy.
The ground quaked as she landed between Sougo and the Time Mazine.
Geiz scowled from inside his cockpit. "Another Rider…?!"
Sougo blinked, awe and fear mixing. "A Rider…? No… something else…"
Riza raised her hand, her Rider weapon forming—a massive, shifting scythe forged from pure chaos. She pointed it at the Time Mazine.
Riza (Chaos): "Geiz Myokoin. You fear the Demon King of Time… but have you considered what happens when Chaos itself enters your game of destiny?"
Far away there Woz the demon king servant. Look at Riza tranfrom to Kamen Rider Chaos he open the book in his hand a see a history being write which surprised him.
Woz:" That..no how can she here, the mother of Maou-sama, She appears when Maou-sama transforms into Oma ZiO in the main timeline.
