Notes:

Found this family tree:
https://www.reddit.com/r/UmaMusume/comments/1mn37tf/a_good_number_of_umamusume_in_game_can_trace/

So before this fic takes place, a powerful woman transported the Tracen students to a theater and sat them through canon and explained how they correlate to our world.

Come on in, the best freakouts are waiting for us.

Chapter 1

Chapter Text

The mysterious woman paused, looking at her tablet.

“Oh, this is going to be the big one,” she chuckled.

Symboli Rudolf paused petting Tokai Teio and Tsurumaru Tsuyoshi.

“The big one, miss? So much family and relationships found out in that other world thanks to you, yet nothing is quite so big as what comes next?” she gestured to the room.

Jungle Pocket was busy fending off Tosen Jordan, King Halo the same towards Kawakami Princess.

Mejiro McQueen’s talking to Ikuno Dictus. Seiun Sky was hugging it out with Nishino Flower.

On the other hand, Oguri Cap and TM Opera O were sulking about not having any kids or partners their counterparts have in the room. Given the size of the room, this would feel worse than you think.

And Kitasan Black and Satono Diamond are not looking at each other.

The mysterious woman claps her hands. The audience snaps to focus on her.

“Okay, the biggest family tree is about to come up. I…need to you all to not hit me. Or hurt each other. Okay? Okay!”

While her captive audience stares in confusion, she taps her tablet.

The screen in front of everyone switches from a transition slide to something…strange to everyone’s eyes.

First, the circle in the center is empty and titled Sunday Silence. That just means that horsegirl isn’t currently attending Tracen Academy with everyone else here for some reason.

That’s the easy part to digest. What isn’t are the lines connecting them to…

Special Week spat out her carrot. “Silence Suzuka is my sister?!”

Silence Suzuka, for her part, covered her mouth with her left hand. She frowned.

“It’s not just us, Spe-chan. There are one, two, three-“

“Seventeen of us present, along with seven others,” Agnes Tachyon cut in. She was trying to distract herself from the revelation that her counterpart’s daughter is Daiwa Scarlet.

Manhattan Cafe was reeling. Her, Tachyon’s sister? That…actually checks out.

Almond Eye was hyperventilating, Fusaichi Pandora futilely trying to bring her back alongside Almond Eye's roommate Blast Onepiece.

“I have foals with my cousin? And my niece?!” she screamed.

Kitasan Black cringed in empathy. She was also one of the Sunday Silence’s grandchildren revealed. She felt a tug on her arm.

Satono Diamond, also one of her newly revealed cousins, the girl she grew up with, the girl whose plush toy she slept with every night and vice versa, grimaced and pointed up to Kitasan’s section.

Kitasan Black, against her better judgment, crawled her eyes towards the screen. She too started screaming.

“What the fuck? What the actual fuck?! Almond Eye was talking about me?! And my kid Equinox?!”

She felt her knees hitting the ground. She didn’t care. She slammed her fist.

Sakura Bakusin O ran away from her classmate, content on never knowing more horrors.

Cheval Grand and Duramente were too happy and hugging it out about discovering that they were cousins and too far from the screaming girls to notice.

And Air Groove was trying to figure out how to talk to her childhood friend Duramente about being grandparent and grandchild respectively. If left alone, she will mull over this for the rest of time.

Meanwhile, Admire Vega was silently and slowly digesting the information.

She thinks of her sister.

Marvelous Sunday saw her and came rushing over.

"Hey, new sis!" she exclaimed. "Crazy day today, huh?"

Admire Vega stared at her. She rolled over the phrase "new sis" in her head. It isn't as repulsive as she expected. She reaches out.

"Call me Ayabe," she extended her arm toward Marvelous Sunday.

Daiwa Scarlet sauntered over to Agnes Tachyon. Tachyon, upon seeing this, started fumbling through her belongings.

"Daddy! Do you wanna hug it out?" she called out, ignoring the hair pulling from her teammate Vodka.

Agnes Tachyon shuddered. Involuntarily, her eyes drifted towards Jungle Pocket. Pocket sensed this and they lock eyes. One homoerotically charged staredown later, and Agnes Tachyon's hand had stumbled upon a flask.

Aha! She leapt up, starting Daiwa Scarlet and Vodka.

"Well, I'm not one for hugs, but this drink will surely bring a great boost to your physical abilities. I just need to test on out, and you seem-!"

And the two has already run away.

Agnes Tachyon huffs to herself and Manhattan Cafe stares in askance.

Vivlos, Verxina, Gentildonna, Loves Only You and Gran Alegria had pulled over Satono Diamond to talk about their parent Deep Impact.

"Girls, what kind of person could Deep Impact be?" Gran Alegria asked.

Gentildonna furrows her brow. "She's not even here to have anything to talk about," she pointed out.

Alegria fumbled her words. "Well, I wish that she could help us all out a bit, you know. She's...she's-"

Verxina cut in, taking a moment to smile at Cheval Grand hugging Duramente. "Whoever she is, let's make sure to welcome her and love her for who she is when she arrives."

Her sisters present mumble their agreement.

They all wonder where are Contrail and all the rest were.

Stay Gold was gawking at her five kids and her grandchild in the other world. Dream Journey, Fenomeno, Gold Ship, Nakayama Fiesta, and Orfevre were just taking it all, staring at one another and trying to parse through their newly discovered sisterhood.

Orfevre in particular was trying to keep up her composure in the face of her daughter Lucky Lilac, who looked like she is having a religious experience upon discovering that her idol is her parent in another world.

Fenomeno, having decided to do something, awkwardly started talking. "So that was-"

Gold Ship also decided to do something. She deliberately stuck her foot out and banged it against her wall.

"Ow, ow, my foot, ow, carry me to heaven, ow," she deadpanned.

"This is such a crapshoot," Stay Gold facepalmed.

"You're telling me," Mejiro McQueen mumbled, suddenly facedown on the floor and stubbornly staying despite Tokai Teio and the rest of the Mejiro Clan present rushing to try to get her up. "I'm responsible for that."

Zenno Rob Roy found herself the attention of Happy Meek.

"Why me? I'm not even your grandparent. The two of you are different," she protested.

"Even so,' Happy Meek pouted. "That she was named after me felt like something that mattered and I wanted to be here with you and talk to you."

Zenno blushed and flailed around to see her roommate Rice Shower, Neo Universe and her kid Sounds of Earth giving her thumbs up.

She gave up and hugged Happy Meek back.

Daring Heart and Daring Tact found each other. The two of them were feeling pretty lost about everything, so Tact set out to find her senior.

"So-" she started.

"I-" Heart started at the same time.

They caught themselves and giggled.

"Wow, am I glad to be your grandmother!" Daring Heart exclaimed.

"But you're not," Daring Tact smiled. "You are a wonderful friend and senior to me. All of this changes nothing about how I feel about you, Heart."

Daring Heart blushed and changed the subject.

"So, Daring Bird." Daring Tact's eyes widened and they both nod. "Let's go find her. I bet she's as great to know as you are!"

"And you shall have my hand to assist you in finding your mother!" The two jumped and clutched at their chests. Symobli Kris S reddened and scratched at her cheek.

"Allow me to assist you in your task, granddaughter of mine," she stated. Daring Tact moves to object.

"Ah, like I said, you are not my-"

As the back and forth continues, Daring Tact's counterpart's great grandparent's counterpart (boy was that a mouthful!) Special Week was crying. Crying at the sight of Buena Vista and Cesario.

"You're both so beautiful and so talented! I'm so happy to see that you both grew up to be the best versions of yourself you could beeeee," she blew her nose into her handkerchief.

Buena Vista and Cesario look haplessly at the onslaught of emotion and turned to beg for mercy from Silence Suzuka.

"Spe-chan, you are as adorable as ever," she said, hugging her friend and motioning the two to come in. They oblige.

So here it was. How everyone took to what Sunday Silence had wrought upon them, some in horror and terror, some in confusion, and the others less so.

The mysterious women took some aspirin. She rubbed her head and smiled. "Damn, this feels like mistake."

"Oh, was it?"

She turned her head to see Gold Ship's boot heading towards her head.

The mysterious woman paled and started running for her life.

Chapter 2: Enter Still In Love and Admire Groove!

Notes:

New chappie.

Chapter Text

The mysterious woman, imprint of something fresh on her face, peered at the crowd.

She snapped her fingers.

In a moment, Admire Groove and Still In Love materialized in the room, to their befuddlement.

Air Groove and Duramente felt something in the air and looked up at the screen.

“My daughter is here,” Air Groove breathed out.

“Mother is here.” Duramente readied herself.

“Wait a second-why am I…?” Admire Groove trailed off. “That picture. Why does it say that Air Groove is my mother? Who is this Sunday Silence that is supposedly my father? Why does he have so many kids?”

Air Groove cut in, putting her hand on Admire Groove’s shoulder.

“Oh, huh?” Admire Groove turned to Air Groove.

“I know that is so confusing, but I also know that you are not alone in feeling like this,” she gestured to the rest of the room.

Still in Love scanned the room and met Neo Universe’s eyes. She lit up upon seeing her roommate and moved over.

“It’s a relief to see that you are okay,” Still in Love professed.

“Oh, big sis,” the blonde said.

This drew the brunette to a stop.

“Big sis?” she asked. Neo Universe smiled and brought over Sounds of Earth.

“This is my daughter and your niece.”

“Greetings, dear aunt!” Sounds of Earth then plucked at her violin.

Still in Love took a moment to blink and moved to embrace the two.
