The Demon Child With An Angel Heart

Halo blackwing is a demon who lives in the underworld
He's different then the rest of the demons, so he tends to hide and stay quiet a lot
One day when he is 8 years old...he goes to earth
He sees an adorable little girl with blond pigtails in a nightgown playing outside in the sunset lighting. She is younger then he's sure, maybe 6. He says hello even though he knows she won't be able to see him just hear him. The little girl looks around "hello? Whose there?" She asks "My name is Halo." The girl smiles, "hello Halo! my name is Lia! Where are you?" He walks right in front of her staring at her from only an two inches away. Little does Halo know Lia can feel his breath on her skin as he breaths.. "..I'm a demon from the underworld, you can't see me but.." he stops talking and gasps as the girl's hand touches his chest and suddenly the girl's eyes go wide. "Halo I can see you!" She laughs. Halo backs away quickly terrified "-w-what?"
He moves faster away and goes back to the underworld
"Halo?? Where did you go? Hello?? Don't leave! Stay with me" she calls out
But all she hears is silence in return
