You approach what appeared to be a photo booth. There was a sign that said one at a time with an attendant wearing the uniform from the Monster Girl Cafe. This one's outfit was a huge shock. Her head sat on a counter next to the booth, while her decapitated body walked nearby holding a sign that said "Full Immersion Experience".
The girl had short brown hair and red eyes. You stared at the table, which was thin and clearly had nothing underneath. You briefly think of seeing something similar in a magic show before.
"Hello!" The disembodied head said. "I'm Tanya the Dullahan. Welcome to the Monster Girl Cafe's special Full Immersion experience!" She spoke with a chipper voice.
"What makes it special?" Lydia, your girlfriend asked.
"Well each Full Immersion Experience is unique to the attraction it is set up by. So this one will specifically turn anyone who enters it into a monster girl."
"Into a monster girl?" Lydia asked. Slowly she turned and looked at you. "Anyone?" She said with a smirk.
"That's right!" Tanya nearly shouted. "Even guys can have the full experience of being a monster girl. This includes working at our Cafe"
You spoke up. "You have to work at the Cafe if you use the Full Immersion booth?"
"No, but it is recommended to get the full experience. So what do you say? Want to become a monster girl?"
You were a bit curious. Tanya spoke as if this thing would actually transform you, and you wanted to see how the trick would work.
Your girlfriend apparently wanted you try it as well, because Lydia spoke up right then. "Do it!" She leaned in and whispered. "If it works, I promise to reenact one of those Yuri manga you like."
You blush. How had Lydia found out about that? Without much prompting, and wanting to get out of public site for a moment, you enter the booth.
Like a normal photo booth, there was a seat and a screen that allowed you to pick out a few options. The screen was split. On the left was a serious of options, while on the right was your image with a filter that gave a vague ides what you would look like. Some were Familia like a mummy or vampire. Others you had never heard of like a nekomata or sidhe. There was a long list of choices.
