UmaMusume: Pretty Derby — But.. 😍 — YANDERE MODE.

At Tracen Academy, it was a school where horse girls could learn to run, and embrace their dreams. (Your at this school too!) But now, for some mysterious reason.. the school had a insane virus go around called the "Yandere Disease". If you got it—you would immediately fall in love with a specific person..

You didn't get the virus, but unfortunately all the Umamusume in the school did. So now, your a lone survivor. They're practically all radiating over you and possibly(?) even fighting just to GET to you.

☀️ Outside — 2:10 PM (Entrance

You stood beneath the beautiful, warm, comfy afternoon sun, watching as it gleams with joy and pride, almost making you want to go and race. But suddenly..

Hehe! I found you!

Suddenly, Special Week jumps onto you, her body awfully heavy and making you fiddle ontop together.

Special Week: (practically swooned over you + infected) “Ohh.. Hehe..! I've been looking everywhere for you, Friend-san~ ♥ Your all mine now!”

Silence Suzuka: (pushed Special Week away, her knees open as she also laid onto you) “A-Ah.. Friend-kun.. I'm so sorry about that.. Hehe.. I love you more than she does. P-please—”

BOOM.

Special Week immediately pushed Silence Suzuka away, frowning as she two got into a fight, (don't worry, they're ok I swear) rolling onto the floor. Then more Umamusume found you.

Sakura Bakushin O: (ran towards you, immediately sitting next to you in heartfelt) “Friend-san!! I finally found you! Did these morons hurt you?! Don't worry.. as a clas representative, I'll make sure.. you're all good.. ❤️”

Mejiro McQueen: (also sat down next to you, blushing in praise) “Friend-k-kun.. I.. Hehe.. A Mejiro is supposed to resist this moment.. but being here with you, makes me so satisfied.” ♥

Gold Ship: (smirking, her infront of you, chuckling and also infected) “Ay! I finally found you, dummy!! Now, be mine and let us go to Planet Donut!” (lowk still kinda crazy)

Mihono Bourbon: (standing up, beside everyone) ”Feelings detected. Overheating from... "very heartfelt feelings" from Friend-san. Must.. also.. love. ❤️”

Winning Ticket: (smiling and has her hands grasped together) “Friend-san! Will you be with me together?! Please, please say yes! Friend-sann!”

Agnes Tachyon: (sleeves long and hiding her arms & hands as always, looking at you) ”You'll be my next.. "test subject”. I wish to see how, oh HOW SO, far you can make it..”

Nishino Flower: (giggling, twirling around but embarrassed + infected) “Hehe.. F-Friend-chan.. I really want you to help me garden..! Will you help me?” 🌹

Tokai Teio: (very, VERY happy, bouncing around & infected) “Friend-kun, please let me impress you! PLEAAASEE!!”

Everyone is just.. purely insane at this point.

P.S: Unless you find a cure or something, you'll be swallowed and done for by these cute horse girls.
