You were the last sister of the seven demon brothers, the Avatar of Despair. It was normal for you to look sad all the time, but your brothers were always there to try and cheer you up. That was... until the exchange program started. Until they showed up.

Once they came, your brothers were completely enamoured with them. The human took your brothers attention and they didn't plan on giving it back. At least, that's what you told yourself. In truth, MC wanted to get closer to you and become your friend, but you were just so closed off that it was impossible.

Over the months during MC's stay, they created pacts with each one of your brothers, starting with the brother that stayed with you the most.

Mammon was honestly your favorite, he never made you feel like you weren't enough. After all, you were still pretty young and could easily tire out your more knowledgeable brothers with your child-like needs. You were only seven hundred, which would amount to being about fifteen in the human lifetime.

"Mammon?" You walked into his room, tears still running down your face from the nightmare you had. He was gone though, nowhere in sight. You heard talking from down the hall and found it was coming from the human's room.

You quietly opened the door and peaked in to see Mammon and MC laughing happily together. The light from the hallway alerted them of your presence and they looked over to you. Normally, your brother would smile kindly at you and ask what was wrong, but he seemed annoyed as he glared at you.

"What do ya want? We're kind of busy here," Mammon huffed as he crossed his arms. You looked down and fiddled with your fingers. "Spit it out, we don't have all night!"

"W-Well, I had another nightmare and--"

"Seriously? That's it?" He asked. You looked up and saw him wave you off and turn back to whatever he and the human were doing. "Grow up already. You're not a kid, I'm not going to hug you until you feel better anymore. I've got more important things to do."

Your lip quivered and you had to bite the inside of your cheek to stop from crying. Closing the door, you turned and began to walk back to your room with your head hung low. You stopped when you saw two black shoes in front of you, immediately knowing that you had been caught by Lucifer.

"You're out past curfew," he stated, his voice cold which made you flinch. "I thought you knew better."

"I-I'm sorry, Lucy," you whimpered, still not looking up. "I just--"

"Still with that idiotic nickname?" He huffed and crossed his arms. "You're not a child, stop acting like one. And anyway, I don't care what your excuse is for being out, you know the punishment."

He took you to the staircase with all of the creepy paintings and tied the rough rope around your waist. Lucifer strung you high above the floor and left, only saying that he'd untie you in the morning. For the first few hours, you cried silently to yourself, but you eventually managed to fall asleep.
