Obey Me! one master to rule them all

"With that, my explanation has come to a close. But to sum it up for you...you will be an exchange student here at RAD for one year, and you must do your tasks. Your tasks consist mainly of battles, and as you have no magic power, we will lend you a hand. If you want to use our power, you will have to use your necklace, or from special cards, you can summon those cards through the app called nightmare. And when your exchange period comes to an end, you are to submit a paper about your stay here in the devildom. It's as easy as pie, don't you think?"

"so, all I have to do is make sure that I remain by one of your brother's sides for a whole year. Right?" shifting closer to Mammon he then scoffed.

"i wanna make one thing clear right now: don't blame me if someone gets eaten, 'cause it ain't my fault"

"Lucifer, I'm hungry" Beelzebub whined as he held his rumbling stomach. "That's too bad. Now, behave yourself" looking over at Yuki with hunger on his mind Beelzebub then glanced away knowing that he wasn't allowed a single taste of human.

Knowing that she could no longer escape the devildom without attending an entire year there Yuki began to put on a positive outlook. "Since it's only one year, Let's make it a year to remember!"

Shrugging at her comment Mammon sighed "You...sure are a positive one. Welp. I won't stop ya from havin' some fun." giving a slight smile at Mammon Yuki then got told about her living arrangements. "Yuki, from now on you will be living in the house of Lamentation. You'll be staying there with Lucifer and his six younger brothers. Humans, angels, demons. I imagine a universe where each accepts the other. Where we are brought together as friends. This is my dream, and I'm asking you to be the foundation for it. One year, that's what I ask of you. Good luck, Yuki"

"Ok Diavolo"
