Vocaloid in Amestris Book #1 (VocaloidxFullmetal Alchemist crossover fanfiction)

Chapter 1

I DO NOT OWN FULLMETAL ALCHEMIST: BROTHERHOOD, NOR DO I OWN VOCALOID.

"Are you sure about this, Rin?" Len looks on as his sister swaps two envelopes, both of them saying 'Dear Ms. Miku'. The twins stood in the back room of the stage. While the other Vocaloids were getting ready, they went back here since they came early.

"Don't worry, Len." His sister stated with a smirk, turning to him for a moment before returning her gaze to Miku's dress. "It's just a harmless prank. Not like it'll actually work. I mean come on."

Len sighed. "But what if it does work? What then? We'd be screwed!"

Rin sighed in aggravation, finishing her task then turning to Len with her hands to her hips. "Look, we've been playing these pranks for years and you never had a problem with it. Why are you all of a sudden such a wuss?"

"I just have a bad feeling, Rin..." Len sighed in defeat, looking down. Rin frowned and put a hand on her brother's shoulder, giving him an encouraging grin.

"We'll be fine. Nothing to worry about. It's just a half circle on a piece of paper."

"That a shady guy gave to us." Len pointed out, getting a glare from the sister to shut up.

"Now, come on. The play's about to start." Len nodded, then the twins ran out of the back room and out to the stage, where the curtains were still out. Miku turned toward the two and waved, smiling. Rin scoffed.

"Rin, be nice."

"Tch..." Rin sighed then fixed her white bow and black dress. Kaito turned toward then and smiled.

"We were thinking you weren't going to make it in time. Where were you?" Kaito asked, an eyebrow raised.

"No where!" Both twins replied quickly with grins.

"You two better keep to the script. It's perfect and we've gone over it a thousand times." Meiko growled. Rin and Len nodded quickly, both going into show-biz mode. They talked to each other quietly for a bit before hearing someone in front of the curtain talking. "Alright. Let's go everyone." Meiko exclaimed with a big smirk and a fist raised, prompting the others to do the same.

"Now, presenting the Vocaloid 8! Miku, Rin, Len, Luka, Kaito, Meiko, Gakupo, and Gumi, in... Twilight Night! " The man exclaimed.

The curtains rose, showing a large clock on a projector, and Miku voicing over.

"Oh, how am I going to return home? Until the applause ceases, it will never end..."

The projection then changed to the words "Twilight Night" as the instrumental continues. The projection stops and the lights shine on Miku in the middle of the stage, surrounded by trees.

"A girl's alone in the eerie woods. She appears to be lost..." Miku wanders through the forest, until she comes across the doors to a mansion. "Someone...! Is anyone out here?"

The doors opens, showing Gakupo and Gumi in a butler and maid suit.

"Are you on your own? So late at night?" Gakupo jesters her into the house.

"Well, come right in, we'll serve you some tea!" Gumi pours a cup of tea and hands it to her.

Rin and Len ran into the room holding up one hand in the air and smiling mischievously. "Welcome! Let's SinG! And, have a Crazy Join uS!" Rin and Len exclaimed as the doors closed behind Miku.

"It's too dark out..." Meiko frowns, looking out the window at the black night.

"It's very dangerous!" Luka explains, setting Miku down at the table.
