The Demon Brothers' Little Sister (Obey Me fanfic)

Prologue

The once-peaceful sky is now erupting with chaos. The angels are yelling and fighting each other, transforming the Celestial Realm into a terrifying battlefield. Their golden blood is splattered everywhere, painting the building and the sky.

You have no idea what's going on. Lilith mysteriously disappeared last week and a few days ago, you saw your brothers discussing something in a very serious manner.



You went to Lilith's room to invite her to join you picking some flowers in the garden. But she is nowhere to be found. You wandered along the corridor and as you passed by Lucifer's room, you heard several voices. You are sure it's your brothers'. You went closer to the door and peeped through it. You heard them mention Lilith, panic and worry were visible in their voices.

"What is she thinking?"

"We have to help her."

"But how? Her fate is decided."

You are determined to ask one of your brothers about it later. That night, you went to bed as usual and today it was Leviathan who accompanied you until you sleep.

"What happened to Lilith?" you asked him.

"We can handle it. There's nothing for you to worry about," he gave a short answer and it made you wonder what happened to her, but being a little angel, no one bothers to tell you.

And today, you are cowering behind a crumbled wall, watching in horror at the scene unfold before your eyes. You let out a small scream as an angel falls mere feet away from you with a spear protruding from his stomach.

The least you can do for now is hope that your brothers are not seriously injured. But you start to get worried as more angels fall in defeat. Your eyes wildly search for them, tears well up in your eyes, threatening to fall at your growing fear. Suddenly, a familiar hand taps on your shoulder from behind, startling you. You turn around and are relieved to see that it is Mammon. You could see a slash on his left arm, bleeding profusely.

He looks at you in pity and pulls you for a hug. You clung to him, seeking comfort in his embrace as tears fell down your cheek.

"I'm scared... Please don't leave me...," you whisper, voice trembling in fear.

"I won't. I'll follow Lucifer and you're coming with us," his face is serious. You could feel that it's time you will fall.

"Close your eyes," you do as he asks. He holds you in his arms, and with a deafening roar, the ground underneath you shatters and both of you fall from grace.

The fall feels so endless. You can feel your skull cracking, allowing a pair of horns to grow. A strong burning sensation emanating from your once white wings, now become a dark shade of purple. You can barely breathe from the immense pain and your vision becomes darker. You are jolted awake from the sudden impact and you realize that you are still safely tucked in Mammon's arms. Your head is dizzy but you force your eyes to stay open. You observe the surroundings and see the fallen angels lying on the ground, wounded and some even in a blood puddle.

"Mammon...," you try to wake him up but tiredness washes over you, leaving you unconscious.
