"Mammon"

"EH?!"

"If you speak of this to anyone I promise you that you won't live to see tomorrow" Lucifer said with his stare that makes mammon flinch

"I'll just go to my room.." Mammon said quietly walking towards the main hall to the entrance

"Wrong way" you shouted

"I know!" Mammon shouted back turning the other way down the hall leaving you and Lucifer in silence

"Uhh (y/n)?" Lucifer finally
spoke up

"Hmm?" You hummed

"The cookies?.." Lucifer spoke making you jump as you ran to open the door as smoke came flying out

"Oh lord" you said waving the smoke away

"Just leave it open, the smoke would air out soon, and we both know those cookies aren't good.." Lucifer said as you sighed

"You're right" you said walking away from the oven as Lucifer followed

"Well those cookies are a goner" you spoke

"there's no point in giving those to diavolo, That would just cause humiliation on me" lucifer sighed

"You know, you don't have to be good at everything right?" You asked when mammon came back into the kitchen

"You're correct, At least I am capable of doing more tasks for diavolo then barbados, except for making desserts that is" lucifer replied making you laugh

"Hey (y/n) asmo wanted me to ask if you wanna come to a party with all of us, even Lucifer if he decides to come" mammon butted in

"Sure-"

"No" Lucifer stopped you

"No to (y/n) not coming or you're not?" Mammon asked

"Both, it's your duty to protect
(y/n) and yet you are inviting her to a party full of demons in which some of them still don't like the fact of a human coming here for the exchange program" Lucifer started lecturing

"Oh come on, i'll be there, I'll watch over her" mammon spoke

"The answer is final, besides the last time you were to protect her you failed miserably" lucifer said

"Like when?" Mammon asked

"Levi when he was to attack (y/n) during their competition" Lucifer answered

"That was only one time!" Mammon shouted

"And the time Luke made a mistake in the syrup for the cake turning us into animals causing beel as a lion to attack (y/n)" Lucifer added

"Okay twice!" Mammon spoke

"How about that time I couldn't barely handle myself due to anger and almost hurted her when she tried protecting luke and beel?" Lucifer questioned

"Third times a charm right?" Mammon asked as you face palmed

"Forget it, (y/n) is not going to any parties here in the devildom unless it's demons who we know including us" Lucifer spoke

"Aww lucifer c'mon, pleasee??" You pleaded gripping his arm

"Yeah, don't be a party crasher" mammon spoke crossing his arms

"You can come with us to make sure" you reasoned

"I said no, besides i'm not a fan of parties" Lucifer replied

"Diavolo is gonna be there, he would be happy to see you" mammon replied causing Lucifer to sigh

"Fine, but you better watch over her" lucifer said sternly

"I will geez" mammon scoffed

"I mean it, if she gets hurt I swear i will hang you by your ankle from the chandelier, video record you and upload it to deviltube" lucifer threatened giving mammon the shivers

(Deviltube = youtube for demons)

"Okay! I promise!" Mammon shouted holding up his hands in defeat

"The party is tomorrow night at eight" mammon said before leaving the kitchen as you sighed

"I'm gonna regret this" Lucifer spoke pinching the bridge of his nose

"Yesss!" You shouted jumping up and down

"What are you excited about? It's just a party.." Lucifer said tilting his head a bit like a dog

"I'm not excited for the party, I get to hang out with mammon!" You exclaimed

"And what's so excited about that? He's.......mammon" lucifer asked

"He's cute duh" you said

"That's the first I ever heard a female that had a liking on mammon" Lucifer replied

"What do you mean? I got myself a pretty cute guardian, yeah some of the things he does is pretty stupid but he's just wanting attention" you said as Lucifer rolled his eyes

"More Like pretty annoying" Lucifer scoffed

"Don't call him that!" You shouted

"I just did.." Lucifer spoke as you glared at him

"Well if you're done fangirling over my younger brother I have work to attend to" Lucifer said

"Huh? What about the cookies?" You asked

"Give them to beel, he's a walking garbage disposal"

"LUCIFER!"
