Next Grand World - [Fate Grand Order / Kamen Rider Zi-O] (2024)

Olga knew she was born to be a queen from the day she was born.

Granted, she didn't know exactly how she knew that; she just DID thank you very much. She could feel it in every fiber of very bones, telling her to take things easy for now, to worry less about all that worthless homework school insisted on giving her and focused all of her efforts on something else, instead.

She's surrounded by clocks on a daily basis, their tick-tocking having become music to her ears, another subtle reminder that the only thing keeping her from that "dream" was time itself. But that's okay; Olga was not too worried about it. Everything will be okay when it happened. She's smart enough, but can make things happen if she really, really tried. It's just not time yet.

Becoming queen was on her mind frequently enough, but it's not something she thought about. She just knew it. It's nice, having such a tangible goal for your future when everyone around you is silently panicking about their career choice. It gives her time to think about other, more fun things in life, like having a nice bike ride around town!

It's good to know that she has a true destiny. It's good to know that everyone was wrong. That everyone that insulted her dreams for being "stupid" and "unrealistic" just didn't know any better. They're harmless. They couldn't hurt her. Even when she goes home recovering from a nasty head wound she got from someone flipping her onto the concrete, she's not hurt. She's going to become queen of all someday. She'll survive it all. She knew better than them. And there's nothing wrong with that.

No, there isn't anything wrong with it. Nothing has ever been wrong with it.

It didn't stop her from being surprised when a man in strange robes came before her while she was going for a casual bike ride, warning her about a red robot.

"You fools could never beat me. You want to know why?—"

"This is you, fifty years from now. The most reviled overlord of time."

"That is… me?"

"My name is Tsukuyomi, I come from the year 2068. The reigning ruler of time, Oma Zi-O, has subjugated our people and created a world devoid of all hope."

"What are you doing?!"

"There's no other choice… We must travel through time… and change history."

"Get rid of that watch! That's enough nonsense of being a queen!"

"It's not nonsense, I want to be a queen! I want to make the world a better place. I want to make people happy! When I think like that, the only choice is to be queen!"

"That's correct, you have to become queen."

"Woz…? What are you doing here!?"

"Zi-O's power is unrivaled throughout time. Use that power and the world, including the past and future, will be yours to shape."

"But if I do, won't I become the most evil overlord of all time…?"

"Which is why you shouldn't! Don't bring about that evil!"

"...I will become that overlord… but I won't be feared or despised. I'll become the greatest, kindest and most beloved overlord of all time!"

"REJOICE! She is the heiress to the power of all Riders! The ruler of time, traveling beyond time and space to reign over past and future…Her name is Kamen Rider Zi-O, and you have borne witness to the dawn of her ascension."

"You want to be queen. Is solving everything by oneself… your idea of what a ruler does? If it is, then there's no point in anyone standing by your side."

"It's about more than yourself, you have to have faith in others!"

"Yes… That's what it means to rule…"

"I'm back!"

"W-Welcome home!"

"I'm starving—"

"Oh, you are? Ahem— the thing is, someone's here to see you and… he ate your dinner…"

"…Ha?"

"I'll make you some more—!"

"…And you are?"

"Just a passing through Kamen Rider." *click* "Thanks for the meal, it was great."

"Hey, wait! Didn't you come to see me?"

"Oh, right… You want to rule over this world, am I getting that right? You can forget all about that dream. Because I'm here to destroy everything."

"Someone's there…"

"Let us speak of dreams— This is what I once dreamt when the world was still young to me. Giant machines laid waste to everything and left nothing in their wake. And all I could do was stand and watch. That was when a man approached me and said—"

"You are a natural-born ruler. You will become a queen, and your duty will be to save this world from destruction."

"That dream… Me?"

"Oma Zi-O…"

"Why are you surprised, my younger self?"

"Then I really am…"

"Do you still not believe in this future? You deny your fate of becoming the overlord?"

"It can't be… This can't be real! It can't!"

"But it is, and this is the reality before you. I wished to become queen and save this World. I am your future."

"No… I was going to do all this! I was going to be—!"

"No, this was what you are meant to do, and in the end—"

"I am you. The greatest, kindest, and most beloved overlord of all time."

"Weren't you saying you'll be a good overlord?! Why are you hesitating?!"

"If I take that… then I'll become…"

"Listen here you! If you turn out to be evil after all… I'll take you down myself…"

"You little hypocrite. Always trying to save everyone yet manipulating Geiz into—"

"No! That's not what I want. I want to help him."

"And you'll use that watch to do that? You're just using him as an excuse to turn into Oma Zi-O. You can go all you want about this "saving" business but deep down, your soul is nothing but pure darkness."

"Shut up already!"

"You can't lie to me. I am you— and you are me."

"You've finally accepted it? That your fate is to be the worst overlord?"

"No, not at all. No matter what, I'll keep trying to be the greatest, most kindest overlord I can."

"Huh?"

"You're right about some things. All those dark thoughts I have… what I truly feel deep down… they aren't completely false. However, no matter what, I won't give up. I will trust in the future and the me that lives in it."

TIME BURST!

!TSRUB EMIT

"Huh? That was…?"

"Time… rewinded?"

"Magnificent, my lady! This is the power you possess!"

"You— were you the one behind this?!"

"No, it was all my will."

"Heads and tails... The past and the future... Light and darkness... These watches rules over the two worlds! Good and evil. Light and darkness. I accept it all! And with that power, I'll create a new future!"

"I'm glad... that I've arrived at this timeline... You've been my comrade... and friend..."

"The Hallowed Hour! The Greatest! Most Righteous! Most Prominent! Most Powerful! Queen of All That Is! OMA ZI-O!"

"My lady…"

"Woz, rejoice."

"Huh?"

"I said rejoice."

"REJOICE! The ultimate time queen who reaches over spacetime and reigns over the past and future. Her name is Ōma Zi-O! We are now reaching the last page of history itself!"

"Olga... The two worlds... are in your hands."

"Let me renew my vow of loyalty. You will rule over this world… into glorious perpetuity.

"...No, I won't."

"Meeting you certainly was interesting, my younger self."

A whirl of emotions filled Olga as she stared at the old woman sitting contently on her throne as the golden light surrounded her.

Oma Zi-O, her future self.

'No, not anymore.' Olga thought wearily but firmly to herself, shaking her head in defiance. She rejected that future, that legacy so many were quick to assume that she would embrace. Maybe in this world, this time, she would have accepted things as they were had she chosen to let everything lay as they are.

But that wasn't the choice she made. She would use every ounce of the demon queen's power running through her veins to destroy this timeline and set things back to the way they were.

It's the least she could do for Geiz, her enemy turned comrade and friend who begged her to become the very thing he went back in time to prevent in order to save everyone.

It's the least she could do for Tsukuyomi, who believed before anyone else that she could be better than what was before her right now and sacrificed her life to stop the brother who took away everything she was.

It's the least she could do for Woz, who was loyal to the very end and deserved a purpose free from the evils her future self imposed on him.

It's the least she could do for the history of Kamen Riders itself that she unintentionally stole and warped to suit her desires.

However, before she could bid farewell to her future self, the whole world began to shake in a way that she did not intend.

"W-What's happening now?!" Olga shouted, snapping opening her eyes while what feels like an earthquake began to run through the space the two were, "Is this your doing, Oma Zi-O?!"

She got her non-verbal answer in the form of the overlord's face - which had the default look of cool, assured arrogance - had a perplexed expression written all over it.

"Can it be? How so-oh. OH!"

The old woman then began to laugh of all things, just as the cracks began to appear all over the space they currently occupied.

Despite her current predicament, Olga couldn't help but stare in baffled disbelief, wondering if the old woman has officially snapped.

"It seems our future hasn't yet been decided yet after all!" Oma finally declared after calming down enough just as a strange, golden light began to consume the space they were currently occupying in its entirety, "Let's see where fate leads us this time!"

Before Olga could say anything in response, the bright, golden light knocked her out cold.

"Unless we regain the light of Chaldeas, humanity has no future."

"The name Chaldea has meaning for you too, doesn't it?"

"No... No, somebody! Somebody help me!"

"Why? Why does this always happen to me?"

"Noooooo!"

Somewhere in Antarctica, on December 26, 201X, Olga Marie Animusphere opened her eyes, her memories of both her life as Kamen Rider Zi-O and Director of Chaldea coexisting in her mind.

"I'm getting the feeling…" She muttered as her vision began to fade to black once more. "...that's something's not right…"

When she would awaken later her, her first instinct would be to blame Decade.

Been wanting to do a Kamen Rider Zi-O x Fate/Grand Order crossover since, like forever. Cuz, like, come on, these two are a perfect match! And thanks to Fireblitz113 of, I am able to turn this idea into reality!

Now, while I debated on whether or not to use Sougo or not, considering the circ*mstances of Part 2 with the Lostbelts and all, I think it would be best to just have Olga take Sougo's place as Zi-O outright and everything that comes with it.

For those in the know, you know what I know I am talking about.

Please leave your reviews and thoughts, whether negative or positive.

Until next time folks!
