A/N: Lucifer and the rest of the brothers are having a bad time....

The House Of Lamentation was silent. No one had dared spoke a word to each other. They tried going from their daily routines.

Lucifer doing paperwork.

Leviathan playing video games, watching his favorite anime, or cosplaying as Ruri-chan.

Satan reading in the library.

Asmodeus doing his makeup or at least try too.

Beelzebub raiding the fridge and Belphegor napping in every nook and cranny of the house.

And Mammon......Oh right. Mammon isn't here....

And that was their greatest mistake they ever made. Hurting the one person that was always there for them and once he left...

Their punching bag quit and ran to the human world. Ran away from them.

They now finally understand...

They finally understand Mammon's worth to them. To all of them.

Who handles the budget costs of the HOL while Lucifer pays for the bills and taxes? Mammon.

Who uses his crow familiars to watch over Devildom to make sure no demon, angel, witch, human, etc, try and foil Diavolo's plans?

Mammon.

Who took care of the brothers during their days as angels during and after the Fall while Lucifer was busy? Mammon.

Who raised Satan as his caretaker when Lucifer didn't? Mammon.

Who was the brother besides Lucifer, that made so many necessary sacrifices just to make sure everyone stayed happy? Mammon.

Who carried the burden and took all the beatings, insults, & punishments? Mammon.

Mammon. Mammon. Mammon.

It was all Mammon.

He did it for all of them. And it took the brothers centuries to realize how much he really meant to them that it was too late to make up for what they done to him.

Mammon loved his brothers. They meant the world to him. But he's sure they don't share the same sentiment for him.

He would do anything for them but they wouldn't do the same for him. That what hurts the most.

They took him for granted and are now suffering for it.

Love can hurt and it can be so cruel...

Six months have passed and all of them, including Lucifer had finally understand.

Mammon isn't coming back. He had cut ties with them and they got no one to blame but themselves for it.

*Obey Me~*

It was another day for the demon brothers to get ready for R.A.D. But tbh, no one was enthusiastic about it. Surprisedly, not even Lucifer.

Once he got up and dressed for the day. He made his way to the Family Dining Room. The rest of his brothers were already there. Besides Mammon of course.

The moment he entered the room, his brothers went silent.

Satan and Belphie had looks full of hatred and rage directed at him. 

Levi and Asmo gave him scared looks.

Beel remain neutral but however, Lucifer knew better that underneath that emotionless expression was a deep resentment for the first eldest.

Lucifer:.....

Brothers:.....

Lucifer:....Good Morning.

Satan tsk at him while Belphegor rolled his eyes. Levi looked away from him and Beel just stared impassively. Asmo is the only one who replied back with a perplexed expression.

Asmo: G-Good Morning, Lucifer...

Lucifer: Hmm....

Lucifer sat down but looked in wonder.

Lucifer: Whose turn is it to make breakfast?

Beel: Today...It was supposed to be Mammon's turn...But....

Lucifer:.......Oh.

Satan: Yeah. Oh. Bet you didn't of that one, Dumbass.

Lucifer: *Warning* Satan.

Satan: *Growls* What?

Asmo: Do not start! Okay! Both of you! You're acting like babies!

Levi: Ha! Same goes for you!

Asmo:.....Excuse Me?

Levi: You're always standing in front of that stupid mirror whining about your appearance. How much of a narcissistic whore are you?

Asmo: DID YOU JUST CALL ME A WHORE?!

Levi: Yeah! I did, WHORE! Honestly Normies like you should just DIE!!!

Asmo: Why You! At least I'm not some stinky otaku who always talking shit about others behind their back!!! Mammon would never treat me that way!

Levi: YOU DO THAT TOO ASMODEUS, WITH THAT STUPID BLOG OF YOURS!!! At least I had a better relationship with Mammon more than you! He d rather have me be in my room than go out to places filled to the brim with people! Maybe you five should stop trying to place your expectations on one another, and stop placing them on me too!!!

Asmo: WELL SORRY IF IT'S HARD FOR YOU!!! BUT IT'S HARD FOR ME TOO!!! BECAUSE OF MY SIN! I HAVE TO STAY BEAUTIFUL OR ELSE PEOPLE WILL NEVER LOVE ME!!!

Levi: HA! WELL YOU WERE NEVER LOVED! YOU MAY LOOK PRETTY BUT YOUR HEART IS UGLY!

Asmo: GRRR! HOW DARE YOU GOOD FOR NOTHING ENVIOUS SEA SNAKE!!!

Belphie: Can You Guys Shut Up?! I'm trying to sleep and Beel's trying to eat here?! 

Levi/Asmo: HOW ABOUT YOU SHUT UP! 

Belphie: Honestly. I wish I've never had stupid brothers like you...You guys are even stupider than Mammon...

Levi: Well I wish I've never had spoiled brat of a brother like you!

Satan: And maybe Mammon wouldn't have been stupid if he wasn't lacking a support system in the form of the majority of you guys always ridiculing him! We knew Mammon would never be quite as smart to maintain decent grades by himself! If we were better brothers to him and help him in academics! Then maybe he wouldn't have left us thanks to your stupid asses!

*SLAM*

Lucifer: ALRIGHT! ENOUGH!!!

Brothers:....

Lucifer: Quit acting like a bunch of children! Mammon wouldn't want you all acting this way. So stop mentioning him already. I'm so ashamed to have brothers like you...

Satan: The same goes for you, Old Man! Stop acting like you never been childish before in your life all because your favorite brother isn't here to back you up anymore!

Lucifer: Satan. I demand that you apologize for that comment towards me. Right. This. Intant.

Satan: Or what? What are you going to do about it, Bitch?

The temperature in the room dropped as Lucifer directed his attention at Satan with cold fury in his eyes. The fourth eldest did the same thing.

Lucifer: *ANGRY* SATAN!!!

Satan: *RAGE* LUCIFER!!!

Belphie: GO FUCK YOURSELF LUCIFER!!!

Asmo: TAKE IT BACK, LEVIATHAN!!!

Levi: MAKE ME SLUT!

They all transformed and another bloody fight broke out after that...They continue to scream at each other. Back then, they all always complain about Mammon not controlling their sin. Now they're screaming and fighting each other for not controlling their own.

Beel: ENOUGH! PLEASE EVERYONE! STOP FIGHTING!

Brothers: STAY OUT OF THIS, BEELZEBUB!!!

Belphie: DON'T TALK TO BEEL THAT WAY!!! DON'T YOU DARE TREAT HIM LIKE MAMMON!

Mammon This! Mammon That! They're all going crazy without him!!!!

Levi: UGGGGGGH! I CAN'T TAKE THIS ANYMORE!!! LIVING WITH YOU GUYS IS HELL ENOUGH!!!

Lucifer: What are you saying Leviathan?

Levi: What am I saying?! I'll tell you what I'm saying! I regret following you!

Lucifer's eyes went wide hearing that. Is he saying what he thinks he's saying?!

Levi: I HATE THIS FAMILY AND I HATE YOU! ALWAYS ACTING LIKE YOU'RE BETTER THAN US! WITH YOUR STUPID PRIDE! YOU GOT LILITH KILLED AND DROVE MAMMON AWAY! NOW MC IS GONE TOO! THIS WHOLE FAMILY IS A MESS!!! IT'S NOT FAIR!!!!

Lucifer: Leviathan...

Belphie: Well Good! Not like you're any better!!!! You used to be so diligent! Once a great older brother! Now look at you! Locking yourself away, ignoring the rest of the world, playing your stupid games, obsessing over a anime girl that doesn't even exist! Honestly! You're more pathetic than Mammon! 

Leviathan: *Crying* JUST LEAVE ME ALONE!!! I HATE YOU ALL!!!

The third eldest ran to his room.

Asmo:....I don't blame him....I didn't want to be a demon. I want to go back to the Celestial Realm. That's where I actually felt loved. Because now. People only care about me is because I'm a pretty face and for my body! But not for me!!!! I'm going to see Solomon!!! At least he cares about me unlike the rest of you!!!

Asmo vanished into thin air no doubt going to see Solomon.

Satan:....

Belphie: Got something to say, Mammy's Boy?

Satan: Shut The Fuck Up Belphegor! What's Up With You?! You take things too far! I always wonder why Beel puts up with you? Don't act like you know shit about me! So quit riling everyone up!!!

Belphie: Well maybe I wouldn't if you stop yelling! I take things too far? What about you, Satan? All you ever do is take it too far. Sometimes I can't even sleep without you being so pissed off about something that you break something! Like the damn WI-FI! It's always our fault and never your own! You're so hard to live with!!! Funny how you claim to hate Lucifer when you kiss his ass at the end of the day by trying to get us all on trouble. You really are just like Lucifer! An asshole who don't care about anyone but himself! You're another reason why Mammon left! I WISH YOU WERE NEVER CREATED!!! 

Satan had enough and flipped the dining room table shocking everyone as he let pit another scream of uncontrollable heartfelt rage.

Satan: I HATE THIS!!!! YOU THINK I WANTED THIS?!! I CAN'T JUST STOP BEING ANGRY!!! EVEN IF I WANTED TOO!!! ESPECIALLY WHEN I LOOK AT YOU ALL! I'M RESPONSIBLE FOR MAMMON LEAVING?! THAT GOES FOR YOU TOO, LITTLE SHIT!!! I'll GO TO R.A.D WITHOUT YOU GUYS! I'M SICK AND FUCKING TIRED OF ALL OF YOU!!! INCLUDING YOU LUCIFER!!! I'LL NEVER FORGIVE YOU!!! JUST DO US A FUCKING FAVOR AND DIE ALREADY OLD MAN!!!

Satan stormed off to R.A.D alone with tears in his eyes.

Beel:....

Belphie: I blamed everyone for this...Come on Beel let's go.

Beel: ....Belphie...

Belphie: ....What?

Beel: Maybe you should go apologize....

Belphie: *Scoffs* For What? Seriously Beel! I can't believe my own twin is taking their side! Always acting like the protector. I can't believe this. We're not in the Celestial Realm anymore, Beel. The brothers you been protecting don't exist anymore and stop acting so innocent! You always leave us to starve when you raid the fridge! Some protector you turn out to be! 

Beel:.......

Belphie: *Regret* B-Beel...I didn't mean....BEEL WAIT!

Beelzebub: *Hurt* Leave Me Alone...*Leaves*

Belphie: BEEL! COME BACK!!!

Lucifer sighs as the last two brothers leave the room to who knows where. He grumbled as he felt another headache taking place. He pulled his D.D.D trying to look for any excuse to tell Lord Diavolo the news that most of them wasn't going to R.A.D.

Lucifer: Looks like your entertainment went on break. Again...

The food at the table gone cold. He was surprised. He was half-expecting Beel to come back and eat the rest.

But the Gluttony brother did not come back. But then again, he shouldn't be all that surprised considering the horrible argument that transpired between them..

Lucifer let out another sigh wondering where did he go wrong? Their family was a mess. Broken possibly beyond repair.

He grab a bottle of demonus, poured the wine into a cup, before taking a large sip. He poured another..and another... Repeating the same process...

He knows whose responsible for this and it ain't Mammon's fault this time...

Lucifer: It's Me...It's My Own Fault...My Pride...Hurt My Brothers...

He felt the tears fall down his face.

Lucifer: I miss Mammon...

There. He admitted it. Ya happy???

Lucifer: I'm so sorry Mammon...I'm so sorry. I failed you. I failed everyone...Without you, I don't know what to do anymore. I need you...

How can he fix this mess???

???: Ohohoho~! Who would've thought the tables have turned against the Great Lucifer~!

Lucifer stiffen. That voice. He recognized it. How did that bastard get in his house without him knowing. He is able to know when an intruder is inside through his spell he casted around the HOL.

???: It's such a sight I've been waiting to see for a very long time...and who would've thought all it took was for his own pride to hurt everyone he loves deadly~! Such a pity~! 

Hearing that cold calculating manipulative tone made his blood boil as he turned to the unwelcome guest whom invited himself into the House Of Lamentation, straight into his dining room before sitting down at the  chair farthest across from Lucifer.

Lucifer: What do you want...Michael?
