It was an average night at the Scarlet Devil Mansion. Well, almost. A week ago, Flandre Scarlet finished watching the first season of My Little Pony: Friendship is Magic on her "slightly" burnt computer, and now she couldn't get enough. Over the week she was browsing pictures and fanfics, until today...
"...You want to what?" Remilia asked her younger sister.
"Visit Equestria! I wanna see those ponies in person!"
"Alright, but where is it, It's obviously not in Gensokyo."
"It's, um..."
"I doubt it's even beyond the Hakurei Border."
"Well, maybe we should ask Sakuya to find out about it. Sakuya!"
In an instant, Sakuya appeared before the vampire sisters.
"Yes, My ladies?"
"We need you to find out where Equestria is."
"Equestria? Is that a world apart from ours?"
"Not sure, but yeah, we think so."
"Well, if it's another world, maybe Yukari might know more. I'll go pay her a visit."
"No need." A voice boomed from seemingly nowhere. A purple portal with red ribbons, known as one of Yukari's "Gaps", opened up above Flandre and Yukari jumped out.
"So, you wanted to know about Equestria, right?"
Remilia spoke up. "Yes, my little sister wants to go there and see the ponies, as she roughly put it."
Yukari chuckled. "Well, if that's what you all want, I suppose I could move the mansion there for a week."
"Why a week?"
"Want to be there longer? I can set my alarm clock to a month later if you want."
"A week will do, Yukari."
Flandre cheered. "Yay! We're going to Equestria!"
Yukari began doing her thing, and soon everyone's vision began to fade and their forms changed. Soon, everyone was unconscious... well, except for Yukari.
"Fufufufu. I guess I better head towards my nap now..." The now alicorn raised a hoof and opened one of her gaps. She lightly laughed as the gap closed behind her.
Remilia was the first to awaken, confused and disoriented. She looked at where her hands used to be, and instead saw red-pink hooves.
"What.. WHAT THE HELL JUST HAPPENED!?!" Remilia's scream woke the other newly-transformed ponies.
"My lady, what's wrong?"
"What's worng! I've turned into a... a..."
"A Pony! YAY!" Flandre was giddy with excitement. She bounced around twice before tripping over herself.
"Ouch... guess it'll take a little practice to get this whole four legs thing down."
"Ok, so what am I supposed to do for a week while we're here?"
"Oh, I know! You can come with to visit the ponies!"
"Sure, I'll just walk outside in the middle of the day. Last I checked, hooves aren't good for holding things!"
"My lady, I could hold your parasol... with my mouth I guess."
"No, that won't do... Sakuya."
"Yes?"
"Prepare the scarlet mist."
"Yes, my lady."
