What if

"Okay, I can do this." Sky thought as she nervously looked at the summoning circle she had drawn with chalk. Grabbing a match stick and lighting it, she carefully lit the candlesticks that surround the circle. Sky dropped the match stick (out of course) and picked up a razor blade. Sky grimaced as she slowly dragged the blade along her arm, making a small cut. Sky let the blood drip for about a second, long enough for the circle glowed a bright red, meaning the requirements had been fulfilled. Sky took deep breaths as she thought "This will work" in her head on repeat. "I request for reality shifting powers or someone that can help me achieve that." Sky said.

"Uh hi." Sky stared at the person in front of her. It look just liked her, but it was a demon.

I'm a alternative version of you, Sky felt the voice in her head. Basically this is what your gonna look like if you have powers. Will you take the risk?

Sky answered with a nod. Okay, now put your hands together with your index finger out and close your eyes. Sky did what she was told and seconds later she felt energy inside her. The energy grew stronger as white light overpowered her. The fusion was complete. The white light disappeared and her hair fell back down along her shoulders. When she opened her eyes again Sky was shocked. She tried to control her body but couldn't.

The fusion is complete, we now share a body. What you did just now was letting my soul into your body, resulting in me in control. But don't worry, I will only take control when you visualize me in your head, also know as "manifest". When this happens, your in your sub-conscious mind right now, and you can visualize yourself to transform back. It's also less flashy than manifesting. You can try it right now.

Sky meekly nodded and started visualizing right away as she closed her eyes. It always helped her with these kind of stuff. When Sky open her eyes again it's back to normal.
