Our sister.... (Obey me) (reader insert) [Old Version]

Side chapter: Like Lucifer

"Where is it..." Y/n mumbled as she looked under her bed, in her closet, on her desk, underneath her water bottle, everywhere. She couldn't find her kitty bank, a cat shaped bank that was a gift from Satan.

It held all the money that she was saving up from Lucifer giving her allowance, since she couldn't work so Lucifer gave her a small amount of money every week. She wanted to buy this doll she saw in the store in the human world. Lucifer had offered to buy it for her but she wanted to buy it herself instead.

She frowned as she placed the money she had gotten from Lucifer earlier on the counter. She left her room, deciding to ask her brothers  if they have seem her Kitty Bank.

She knocked on the closest door to her room, Levi's, He opened the door after a few minutes he looked down to find Y/n standing there quietly.

"Levichan.. Have you seen My Kitty Bank? I left it on my desk and now it's gone..." She fidgeted slightly. Levi looked at the female, thinking for a few minutes and shook his head.

"Okie.. thank you..." She continued to go to her siblings rooms, ending up with the same result. She reached the second last of her siblings rooms, it was only Mammon and Lucifer left.

She knocked on the door.

"Mammon...?" She mumbled as she opened the door slowly, to see if he was inside, her eyes widened as she saw her Kitty Bank laying on the ground, broken open with a few coins laying around it. Mammon was sleeping in his messy room, snoring away.

"MAMMOOON!!" Y/n Yelled loudly, so loud that the entire house heard the cry as she yelled out.

Mammon woke up to find his furious younger sister, who was crying, also standing in her demon form.

"What's going on?" Lucifer asked as he appeared behind them along with the rest of the brothers, looking at the scene in front of them, of crying Y/n in her demon form and Mammon who was slightly confused, and a broken Kitty bank.

"Mammon! How could you! You took my money bank! Kitty is dead now! You killed her!" Y/n cried as she pointed to her Kitty bank that was cracked open and laying on the ground.

"MAMMON!" Lucifer yelled as he realized what happened. As Y/n stood crying, yelling at Mammon, along with Lucifer now, The rest of their siblings were shocked to see what was going on.

"Why doesn't Lucifer do that to Mammon when he owes me money..." Levi said as he watched as Lucifer was going to practically Kill Mammon for stealing Y/n's money and broke her bank.

"Y/n's his favourite obviously." Satan replied as he watched Y/n also Yelling at her big brother, tears streaming down her face from sadness.

"Y/n reminds me of Lucifer right now." Asmo pointed out as Y/n was acting like Lucifer as she was yelling at Mammon who stole her Kitty Bank.

"She's most likely be like Lucifer when she is older..." All the brothers, except Lucifer and Mammon, shivered of image of their cute and kind sister as Lucifer
