Promise

A/N: Hello everyone! Welcome to the prologue of Promise, an AU fic which will center mostly around adorable child!Akane and demon!Kagari trying to live under the same roof. But, don't worry, there is an actual plot, I just need lots of fluff, ok? Also, I want to credit cherryblossoms86 for helping me with this story. I'm very scatterbrained and I always need someone to help me sort out my thoughts, so thanks again! Please drop a review if you get the chance and tell me what you think!

Disclaimer: I do not own any of the characters of Psycho-Pass (although I wish I did).

Chapter 1- Prologue

-I'm a hostage to my own humanity-

The sky is dark and the room is quiet when her prayers are seemingly answered by a bright-eyed boy crashing through her window. The child is startled, but not frightened by the visage of a strange man in a long coat. Wide eyed and curious, Akane reaches for the man, bare feet padding against the wooden floor. The stranger shakes pieces of glass off his coat, cursing loudly.

As she walks closer she notices two small ivory bumps on his head, curved and sharp. They grow into full out ram horns, one side containing a jagged line down the middle. The child reaches out, grasping onto one of the horns. It is smooth in her grip and she giggles.

"H-hey kid, stop that!" He pushes the child back gently, keeping her away from the broken shards of glass.

"If you can see the horns and," an arrow tipped tail emerges, flickering in the soft glow of the moon, "the tail then you must be my contract."

"Contract?" The child tips her head to the side, still intent on grabbing onto his horns again.

"Gah, stop! It's pointy! Dangerous, understand?" The girl nods slowly, returning her arm to her side.

"Geeze, my first contracts a kid? No matter…" The man bows, placing his hand over his heart.

"My name is Shusei Kagari and if you agree, I can help find your parents' murderer."

"You'll help me find who hurt mama and papa?"

"Yes. But, I need something in return. Your soul, to be exact."

"Soul? Are you a demon, mister?"

The man sighs. "Yes. When you die I'll take you to He—"

"Deal!"

"But I wasn't done yet!"

"No worries!" The brown-haired child smiles, reaching up to pat the man's head. "I think you're lying about the demon part. You've got to be an angel! I've been praying every night for God to bring me someone to help me find the person who hurt my parents!"

"Listen, kid—"

"My name is Akane Tsunemori and I'm almost eight years old!" The girl pouted, cheeks puffed up.

"Well I'm a demon and over three-hundred years old. Listen, this agreement cannot be taken back. It's final."

"Ok. I still say yes!"

The man feels the urge to face-palm but settles for a sigh, returning to the broken window.

"Fine. Contract accepted. I'll be back in the morning, Akane-chan. Until then, rest, and I'll figure everything out later." The demon jumps through the window, landing on his feet. He smirks, looking at the awe-struck girl.

"Ok, my mister fake demon!" She waves enthusiastically at the fleeing boy, laughing when he clumsily trips at her statement.

"I am a demon!" He yells back, disappearing into the night.
