E2 - Outside of the Dance Hall
The girls all arrive at the Dance Hall to find that the meet and greet event has ended. Those who came here for that (everyone but Aya) are naturally disappointed. They decide to turn around and leave, but are stopped by the sounds of the hall doors opening, and a very familiar pop sensation stepping out. She waves to the group of four.
"Hey, Aya, you're here!" she yells "And you brought friends!"
Yes, that's certainly the world famous E!Erin in the flesh. She rushes over the the girls, and ushers them inside the hall. Of course they all comply. It's a celebrity, after all.
E2 - Dance Hall
The large hall looks somewhat smaller than usual, now that it's deserted of people. The only ones in this hall now are Aya, Elisabeth, Hikari, Irina, Silvia, and Emily. Silvia and Elisabeth immediately recognise each other from the incident at the dock. Is this another fated meeting between magical girls? You senses seem to suggest so.
"You're probably wondering why I brought you in here - well, most of you are - and the answer is simple. Each one of you has received the power of Alistair, and so have I. But my powers aren't really suited for combat. So I talked to Aya here" she points at her "and decided that I'd test out my abilities with all of you. I'm not gonna be a fighter, I'm gonna be your support."
She does a twirl, and makes a fashionable pose to draw all attention to her.
"I'm Emily Erin. You can all call me Emily. My powers allow me to control what you perceive. Sight, smell, touch, and so on. All of your senses I can manipulate with my magical power. So without further ado, why don't I transform and show you?"
Emily puts a hand to the sky, and light envelopes her body. Purple ribbons completely wrap around her, then burst into shreds, revealing Emily in her usual stage costume. It's a tiny chest jacket, skirt, and boots. Everyone feels a sense of admiration. They feel pumped, excited. Something about Emily's magical girl form creates an atmosphere of cheerfulness. Like going to one of her concerts.
"So, how about it guys? You wanna help me test my skills?"
