Fate/Genshin : Genshin Impact x FGO crossover

A Rayshift goes wrong and sends Servants tumbling into the world of Teyvat. A teleport goes wrong and sends vision-wielders into Chaldea via the Grail System. That's how the two worlds first met. And it wouldn't be the end. This is a collection of stories where characters get sent across worlds. Lumine is the active twin. Gudako and Gudao are the same person and, just like in-game, can switch on will. Listed as Female lead bc Lumine is active twin and Gudako is the defaulted one. Due to some complications, this fanfic's updates have been moved! I may add them here in the future though.

Field of Wind : Jean

Artoria looked up, the hair on her skin rising at the feeling of pooling mana. She felt the mana swirl around like a gale, moving in a circular motion around the women that stood just a ways from her. To Artoria, she looked like a mirror image of the time when Artoria was king. Powerful, unwavering, and bold.

Whoosh~

Jean concentrated, forcing out all of her doubt and worry. She had no need for such things on the battlefield, especially when it was a fight for life. As she emptied her mind into the wind that she called home, a gust of words suddenly appeared, begging to be spoken.

And so she did.

"Barbatos, guide us-"

A swirl of wind, followed by the faraway roar of a cyclone. A response to the call.

"As I swear by my sword

Devise, attack, protect, defeat-"

Gawain felt energy return to his tired body and his sword suddenly seemed lighter and easier to swing. To his left, Lancelot also felt the same. It was as if a soft breeze had entered their tired bodies and lifted their spirits and guided their hands.

"This field brought by the Wind-

Will lead us to victory!"

On those words, Jean's eyes flared open as she turned her sword swiftly like a key in a lock. She didn't need to look down to know that the field she had created with her vision was appearing around her. As she brought her sword down in a grand slashing motion, Jean shouted out the last line with all of her heart.

"Roar, O gale that blows without restraint! Dandelion Breeze!"

With that, vivid green light flared up all around her, healing the wounds of her allies and restoring power to them.

Artoria smiled. She had done it.

"Congratulations, Jean! That is your Noble Phantasm! Of course, there is no room for hesitation on the battlefield, something we both know. And so, as a fellow knight, I implore you to witness mine!"

Facing the wave of enemies, Artoria took up her signature stance.

"This light is the planet's hope-

Proof of the life that illuminates this world!

Let us end this!

Excalibur!"

(cough EXO-CALIBAAAAAAAAAAAAAAAAAAAAAAAAH!)

And when the dust settled, all that remained were the remnants of the beasts and the 4 knights. But more enemies were still coming, like a dark wave on the horizon.

"Heh, perfect timing. My king, Jean, you two can't just leave us out as well. Bear witness to ours as well!"

"Reach the edge of the world and go beyond it's limit."

"O distant king, witness this light!"

"Arondight Overload!"

...

"This sword is a replica of the sun."

"Its flame shall cleanse all the impurity of this world.

"Excalibur Galatine!"

...

...

"Hah~ what a great workout!"

"And perfectly in time to! Look!"

The 3 looked to the horizon where Gawain pointed and watched as the last of the sun finally disappeared below the horizon.

"Ah, Master will be happy with all these materials."

On that note, the 4 began to pick up the dropped materials and gather them into a large pile.

"Hey Jean."

"Oh, Artoria, what is it?"

"Who...who exactly is Barbatos?"

"Every region has an Archon that essentially represents that region. Barbatos is the Anemo Archon of Mondstadt, literally the Archon of Wind."

"According to legend, he teamed up with the Dandelion Knight, Vanessa, of 2000 years ago to take down the tyrant that had ruled Mondstadt and the nobles that had been discriminating against the people."

"That tyrant had been the Anemo Archon of then and so when Barbatos had defeated him, he then rose to that position. Utilizing his abilities, he helped build the new Mondstadt from the ground and aided Vanessa in protecting the new city."

"Unlike most other places, Barbatos is very lax in his watch over us due to his belief in freedom and so Mondstadt became the city of freedom where one follows wherever the wind takes them."

"I see...then there is nothing to worry about."

"Hmm? What's the matter?"

"In this world, the name Barbatos belongs to one of the 72 demon god pillars, specifically the one that holds the 4th seat within the Temple of Time. Normally, such things would be alright since it has no effect on us, but...."

"It was only a while ago that Master Gudako and the rest of us at Chaldea faced again those 72 because they actively tried to incinerate humanity. We managed to defeat them, thankfully."

"Oh…"

She suddenly straightened up and put her hand on her chest.

"I swear on my position as Dandelion Knight and my life that our Barbatos is nothing like that! He would never turn against his people of Mondstadt or anyone else!"

"I know."

"Then-"

"I just wanted to check. Emiya-san and Cú both figured your world's deities, while sharing the same name, are not the same as the ones we have met. But as a warning, Barbatos was active in the London singularity and the Temple of Time so it is likely that some servants still bear a certain dislike to him(?)."

"I will keep that in mind."

Shaking hands, the two then joined Lancelot and Gawain who had finished up gathering the remaining material.

The two male knights nodded towards Artoria who then proceeded to raise her hand a press a button into her ear.

"Request to rayshift back to Chaldea."

A few seconds passed for the voice of Da Vinci was suddenly heared.

"Confirmed and cleared. Let's get you guys home."

And with that, the trip on the sand was over.

.....

....

.

Because I felt like it and because she got a swimsuit costume. I tried y'all. XD

Below is the description of a summer-exclusive servant stylized in the a similar way to the in-game and wiki descriptions.

Jean(Summer)

Class: Lancer

-

Desc: After Barbara and others spent hours designing and perfecting an exclusively tailored dress for Jean, they presented it to her. Shocked by such a wonderful gift, Jean had to accept it and in a flurry of motion and activity, Jean appeared with a new, breezy, blue dress. Elegant yet free, it truly symbolizes the great Dandelion Knight of this era. Plus, it was perfect for the summer break that Jean would end up experiencing shortly afterwards. Although, in her world, nothing about her changed fundamentally, Grail-kun of this world likes to have (questionable) fun. So, when she ended up visiting Chaldea again, Jean suddenly found herself utilizing a new weapon and a different set of skills.

"Huh? Have I used this before? I've never used such a weapon in my life! Although, I suppose a change might be relaxing~."

And with that, our great Dandelion Knight breaks out a beautifully crafted spear made of plastic and foam. The tiny print on the side says it's borrowed from Okki which is interesing since Okki claims to have never seen it before....

She still uses it like a sword. Oh well.

-

Madness Enhancement(Summer) E- (D):

Jean thinks she's living a wonderful dream and thus, she acts as carefree as a woman her age does. However, labeling this as Madness Enhancement isn't exactly correct. She hasn't lost any ounce of reason. Rather, she's relaxed the guards she always has up...which somehow increased her power output as well since she isn't restraining herself as much either.

-

Riding C+:

As a knight, she was trained in the art of riding horses.

-

Traveler C:

As someone from another universe and reality, she shouldn't exist in this world. Slightly separate classification from the foreigner's class skill.

-

Dandelion Breeze C:

Her original noble phantasm now transformed into a skill. As a result, it has lost some of its effects.

"I don't really understand, but something about the sea overrides the usual breeze that comes when I call out."

-

Leo Minor, the Shining Star B:

Her corner of the starry sky that brightens as she gets stronger. Due to the vast, open sky on the beach that essentially strengthened her connection to the sky, this skill came into existence.

-

Dandelion's Gale Waves:

Utilizing her new lance and the ability to run on water(trained), Jean dashes over the waves to the enemy and slices them in a blinding fashion before stabbing(shooting) them with enough force to throw them far away.

While she desperately denies this, it seems that her stress level jumps every time she sees an enemy. As such, to fully enjoy summer and get rid of the stress, she puts all her power into the last stab(shot) to thrust(throw/yeet) them far away from her-something akin to throwing away one's worries.

"Hey Gudako! Please stop changing Servant profiles in the Chaldea data register! That is not the reason as to why I gave you the password into the database!" ~Da Vinci

It seems the yeeting will not stop any time soon.

-

Chant:

I wonder what scents will arrive on the sea breeze~

While I may be the Dandelion Knight

It's okay to relax once in a while, right?

So, let me enjoy my vacation!

Go away! Dandelion's Gale Waves!

Ah~, the sea is beautiful today.

-

Extra: As someone from another universe named Teyvat, she should not exist here. Actually, her very being intrudes on this world and its laws which places her in the category as 'able to destroy the world'. However, due to her limited abilites, she is not considered a true 'Threat To Humanity'. However...

Her potential is very high, especially when utilizing the foreign 'vision' from elsewhere. Since she is still 'alive', she can still experience 'power ups', something most other Servants cannot due to having already reached their pinnacle and being 'dead'. As such, should she ever turn her back on humanity or the world and seek to destroy them, the wills of this world will definitely send someone to counter her. The likelihood of her reaching her highest potential is near zero, but even the smallest possibility will alert the guardians who protect this world.

This also happens to make her more effective than others against threats foreign to this world.

But....

"You want me to fight an evil miss Abby? Are you right in the head? That's a child!"

"Miss Hokusai!!? She's a little girl too!"

*Slight spoiler*

"Her too? But she has such a terrible history and is innocent in all this! No way! I am not hurting miss Yan!"
