You had the strangest dream...

You were walking back home at night, only to look up in the sky and see a supernatural battle between a two spiritual beings who were just flying above your head.

The first was a gorgeous woman with orangish blonde hair wearing a black shihakushō. The other was a humanoid with a large hole in their stomach being wearing a white outfit and a skull fragment over their face like a ballroom mask.

You watched as they flew through the air attacking from all angles, feeling the shockwaves of their clashes despite how high up they were. Eventually the woman was victorious and had successfully slain her opponent, but she immediately plummeted straight down afterwards, and she landed just a few feet away from you with a loud THUD.

You ran over to check on her. She had been terribly wounded and exhausted after the battle, and she could barely stand. It was then she made eye contact with you.

"You... can see me?"

She winced from the pain, but never took her eyes off of you. She began chanting something strange under her breath. Her body glowed before she lunged after you; her spiritual being phasing through you.

Next thing you knew, you had woken up in your bed. Perhaps none of that really happened last night?

You got up and went to brush your teeth, only to realize something was off. Your eyes were very distinct shade a blue opposed to your usual eye color, and there was a strand of orangish-blonde hair in front of your head. Almost like-

"Oh, you're awake! Hello!"

You heard a disembodied voice speak to you.

"Don't worry! You're not crazy! Hi, I'm Rangiku Matsumoto. I'm a Shinigami. My gigai was destroyed and spiritual body was severely damaged during my battle last night, so I needed to borrow your human body via a special binding Kidō."

You realized were possessed by a shinigami...

"Don't worry, it's not permanent! It's just until I heal up! But... you might notice a few side effects."

You realize your body is... changing.
