Before we start...A little funny humor...

Short Intro: Lucifer & Michael's relationship in a nutshell.

Lucifer: *Minding His Own Business*

*SPLAT*

Lucifer: WHO JUST ASSAULTED ME WITH A CHALUPA?!!!

Michael: *Appears* You Don't Have A Brother~!

Lucifer: Yeah...Which is why I took yours! 

Mammon: ???

Michael:Grrr.....

Lucifer: Actually. I took both of them.

Raphael: ???

Michael: *TRIGGERED* RAAAAGH!!! LUCIFER!!!

-LOL-

Onto the story...

*Obey Me~*

A/N: Lucifer misses Mammon...

Warning: Slight hallucinations & violence...

Lucifer came to R.A.D alone...as soon as he entered the halls. Everyone begin looking at him. Why he's not surprised...

Despite doning his perfect appearance, most of the demons at R.A.D looked at him wary and afraid. Even more than usual...

Looks like the rumors about his brothers leaving for the human world had spread like wildfire and they're all probably wondering what's going to happen to Devildom now?

Lucifer just sighs avoiding all the stares. Even if he did so much as gaze at the other students, they would either froze or looked in another direction to not be seen by his gaze.

His brothers...

Belphie... 

Beelzebub...

Asmodeus...

Satan...

Leviathan...

Mammon....

They all left him...

Lucifer wouldn't be lying if he said he didn't felt abandoned but he does know he brought this situation upon himself.

His brothers may have been annoying...

But he misses him. All of them. Even Mammon.

Mammon.

His stupid, loud, foolish, annoying, cute, younger brother.

The very one he took for granted the most.

Out of all the brothers. Mammon was his first.

His first brother...

The one that was once under Michael's wing and given to him.

Mammon was special to Lucifer in everyway.

The relationship he has with Mammon has one difference from the others, which is that Mammon has successfully been there for him emotionally, and got him to back off on being harsh on another brother - that brother being Belphegor...especially that one time when...

"Lucifer... it's been hard for Belphie. With what happened to Lilith and all, he has it harder than any of us..."

.

.

.

In the closet to age, Mammon was most powerful after Lucifer, and therefore made the biggest difference to Lucifer's side in the Celestial War.

Mammon also had the most to lose, as his position was probably pretty high by this time, even with his rebellious nature. He was a fallen warrior after all.

Lucifer has such a soft spot for the Avatar of Greed.

Mammon didn't become rebellious when he fell, he was already a rule breaker....to the extent that Michael couldn't handle him, and Lucifer took him under his own wing. 

Though Michael had bigger him about Mammon was always cute...even if he is now a demon. 

Lucifer would never admit it but...he was slightly jealous of Mammon. Mammon was always high and free spirited. Never one to hold down how he felt and stay true to himself. Lucifer, on the other hand, had to throw away everything, even his own livelihood, to become trapped under the constant pressure of being Diavolo's servant and the oath he pledged to him to help him fully run Devildom.

But Lucifer knew he was also to blame for Mammon leaving...

His selfish desires to turn Mammon into being like him, he put him on a pedestal and then pressured him through a lot of expectations...

Lucifer: Mammon...(I miss you...)

Suddenly, he saw a mop of white hair passed by. His eyes went wide and immediately went into flight mode charging at the person.

Lucifer: *Hopeful* Mammon?

Demon: Huh? I'm not Mammon...

The demon had dark tan skin and white hair. However his eyes were different. They were green compared to Mammon blue eyes with a tinge of yellow. 

Lucifer: Oh...Please Forgive Me...My Mistake...

Demon: Okaaaaaaay....*Quickly Leaves...*

Lucifer:....

???: Lucifer?

Lucifer turned his head to see another white hair person. 

Lucifer: Mammon-?! Oh...No...You're not Mammon.

Raphael: Are you okay? You look more pale than usual. 

Lucifer: I am fine, Raphael. Thank you for the concern. But it's not needed. I just need to attend classes than have my meeting with Lord Diavolo.

Raphael: If you say so...please forgive me for prying into your business. I have also matters to attend to. Have A nice day...

The angel leaves to his own classes as Lucifer felt another headache growing.

Lucifer: (If it wasn't for his mannerisms. I almost swore he would be just like Mammon...I hope I'm not losing m my mind...)

*Later*

After classtime was over. The Avatar Of Pride packed everything up to begin heading over to the student council.

Lucifer: (I better get there on time. Barbatos does not like tardiness.)

???: Hey Big Bro! Look what I got!

Lucifer: (Huh?)

Brother: Oh. You take it from someone?

Greed Demon: Yep! That's right! I managed to pickpocketed it from a wondering idiot not too long ago.

That voice...it sounded so familiar to him...

Brother: Ha! You're becoming one heck of a demon after all.

Greed Demon: Yeah! Thanks to my sin I'm going to make it big!

Lucifer couldn't believe his ears. He went for the source of the voice. It sounded almost like Mammon! 

Greed Demon: Man! Being a demon is so awesome! Let's celebrate at the casino later!

Mammon! Mammon! Mammon!

Brother: Oh? So you're offering?

Greed Demon: Yep! I'm telling you brother! You and me! We're gonna make it big!

Lucifer had to put a stop to this!

Before he even realized it, his dark aura sky-rocketed and soon enough, it scared everyone present in the halls.

Greed Demon: What the-?!

*SLAM*

Lucifer: What do you think you're doing?

Greed Demon: Lord L-Lucifer?! H-Hey Man! Lemme go!

Lucifer: Do you have any idea what your doing?

Greed Demon: I didn't do anything wrong man! Put me down!

Brother: Y-Yeah! Leave my brother alone! Let go of him!

Lucifer ignored the other while glaring at the Greed Demon.

Lucifer: How dare you tarnish Lord Diavolo's reputation!

Greed Demon: I-I was just-!

Lucifer: I don't want to hear it! I told you this many times! Time and time again! Why won't listen to me?!

Greed Demon: H-Huh? What are you talking about?!

Lucifer:  You think you can do these things but you just can't MAMMON!

*Silence*....

Greed Demon: W-What? I'm not Mammon...W-What are you saying?

Lucifer:...?!

He's right...He's right....How could Lucifer forget...How could he forget that Mammon isn't the only greed demon in Devildom? Besides...the young greed demon looks nothing like Mammon. It's just that his voice sounded similar, that's all...

But yet...everytime someone stuff goes missing...everyone would assumed it's Mammon...even if it wasn't him...They just make him the scrapegoat...

Lucifer:......

Greed Demon: *Crying* P-P-Please...Let me go...I won't do it again...I'm sorry...I'm sorry...

Lucifer let's himself go and the crying greed demon hid behind his brother as the older one looked at Lucifer with rage in his eyes...

Was he Pride? Wrath? Or Another Greed Demon?

Lucifer didn't know nor bothered to care anymore.

He just made a fool out of himself in front of everyone the moment Mammon's name slipped through his lips...

Brother: What is wrong with you? How dare you attack my little brother just because he pickpocketed some money!

Lucifer: He....He's not supposed to do that...He was indulging in his sin and-?!

Brother: So fucking what!?! He's a demon! He's supposed to indulge in his sin! How would you like it someone told you to stop being prideful all the time?!

Lucifer:....

Brother: Man...No wonder your brothers wanted to get away from you. You're INSANE!

Lucifer: My...My apologies.

Brother: Man! Fuck You! Stay away from us! *Mumbles* Some Demon Lord You Are. You're Pathetic...

The brother took his crying brother under his wing and they left leaving Lucifer in the halls feeling very embarrassed as all eyes were once again on him...

Lucifer:....*Sighs*....(Maybe he's right...I must be losing my mind...)

*Later*

After the incident, Lucifer was in trouble as he now found himself in the Student Council Room with Diavolo & Barbatos both giving him a stern frown. Earlier they were supposed to have a meeting to discuss about the financial situation and the troublesome position of the six missing demon lords...but now, since the incident of Lucifer assaulting a student for no reason came to light...and to add more fuel to the fire regarding Maddi's wherabouts. It looks like they got bigger problems to worry about now. 

Diavolo: Now... Lucifer, tell me, regarding the incident earlier...What were you thinking?

Lucifer:....I...attacked that young demon because he was indulging in his sin and...

Diavolo: Lucifer...we been over this...

Lucifer: I know...I just...I just...

Noticing he had no excuse, Lucifer started fumbling over his words. Shit, he felt absolutely pathetic...Usually, Sit he has a problem...Mammon would usually go out of his way to help him and-?!

OH.........

Lucifer:......

Diavolo: Lucifer....

Lucifer: Mammon...

Diavolo: *Raised Eyebrow* Lucifer...?

Lucifer: Mammon...Mammon...
Mammon...

Barbatos: Lucifer...Is everything okay?

Lucifer: *Losing It* I hurt him...I hurt him...I hurt him...

Why... Why is the world being so cruel to him now? He apologized didn't he? He said he was sorry.. he's sorry.

He can hear his pride talking again...

Your apologizes aren't enough.

They'll never be enough.

What you did is unforgivable.

You lost it all once.

And now you'll lose it again.

He blinks away the white dots in his vision, blinks away the tears, instead letting them slip down his face, and then he hears it, the raggad breathes, the quiet sobs...

Another sob racks through his ears, and he feels his body shudder.

Diavolo and Barbatos couldn't believe their eyes and ears...Lucifer was crying...

They haven't seen him cried this much...

Since...The Day he fell from the Celestial Realm...

Diavolo: Lucifer....

Diavolo brought him into his arms and let's the other man cry...

Lucifer: *Crying* I hurt him...

Diavolo: I know...

Lucifer: Lord Diavolo...I hurt him...But I love him...I just...I just wanted to protect him...I just...wanted to protect my family...I didn't want to lose them...Not again...

Lilith....

Diavolo: Oh Lucifer...I know you do. But that's what happens when you love someone so much that you end up hurting them...

He was right. All this happened was because Lucifer was too stubborn to admit his mistakes...

Too stubborn to apologize...

How...How can he make it right...?

How can he make it up to Mammon...To all of his brothers...

Diavolo: You must be under a lot of stress...We will hold off your punishment later. Right now, go get some rest...

It wasn't a suggestion but an order.

Lucifer: ....Yes Lord Diavolo...

*Later*

Lucifer, sat there in his room, looking absolutely miserable while he only had his record player to keep him company.

He then droned on the advice Simeon gave him...

*Flashback*

Lucifer: Simeon...I'm doing my best. I did everything for him...So...why couldn't he understand?

Simeon: That's because of how you treated him, Lucifer.

Lucifer: I was only disciplining him. I was disciplining my brothers and-?

Simeon: Lucifer. Discipline and abuse are two different things.

Lucifer:.....

Simeon: Ever since he came to me at Purgatory Hall. He had a hurt yet determined expression on his face. Almost like he had enough...I recalled healing the scars he had on his back even if most of them wouldn't go away...

Lucifer:....

Simeon: I will say what Lord Diavolo said to your other brothers earlier...He never thought he was good enough...but did you had to make it worst...?

Lucifer: Simeon...

Simeon: *Stern* No. Listen to me for once Lucifer. You treated Mammon like he was nothing but yet he stuck around thinking you would change...

Lucifer:...

Simeon: You broke his trust...you ruined him...shattered his heart into a million pieces...and worse of all, took away the wonderful person he was before you. Because you wanted him to be different.

Lucifer: I...

Simeon: Lucifer...Tell me...did you truly wanted Mammon or did you wanted a more submissive brother who would obey your every order without question???

Lucifer:.....It almost sound like your accusing me of liking Raphael more than Mammon.

Simeon: I wasn't accusing. I was asking a question. And it seems to me...I got my answer...

Lucifer:...*Sighs*

Simeon: You hurt him Lucifer...you need to make up with Mammon...or else...your relationship with your brothers will be ruined...forever...

Lucifer:....What should I do?

Simeon: Start little by little...Sure he may not open up to you at first and probably won't forgive you for a while. But if you're willing to prove that you can be a better brother to him. Then again, start little by little...

Lucifer:....

Simeon: Also. I have to tell you something. Mammon has a daughter.

Lucifer couldn't believe what he was hearing. His baby bro with child? How come no one has told him yet?!

Unless...Is he talking about the human child that Mammon gave up to the witches a while back...?

Did he adopted her?

Simeon: She is a very darling young girl. She and Luke are good friends. He's absolutely smitten with her. She has a bright future ahead of her. But I suggest you be careful when you're around her. Mammon won't open up to anyone that poses a threat to his dear Kanon.

Lucifer:....I understand.

Simeon: It's not too late to make things right...

*End Flashback*

He hated to admit it but Simeon was right. It wasn't Mammon that needed him. It was Lucifer that needed Mammon. To keep things stable in the HOL.

Now that he was gone. Things have taken a turn for the worst and all the brothers left him to go be with Mammon.

Lucifer:....Mammon....

He then listen to his record player...

*Rock On*

He remembered this song...he and Mammon sang it together in the music event...

Lucifer: You've always been a pain in the neck. A real handful.

Mammon: Don't say that, you'd be nothin' without me!

Lucifer: Well, I do trust you the most.

Mammon: Hey, Stop it Right There! That's Cheatin!

Lucifer: You better live up to your brothers' expectations!

Mammon: Because from now on...

Both: I trust you with all I've got!

Lucifer/Mammon: Just Dance, Unrestrained, Rock on!! it's Impossible To Behave Like A Good Boy~! Let's Go Wild, More And More! Come on Everyone (Hey)! Keep Your Hands Moving~!

....

Lucifer:.....

He can't sit here anymore...

He needed Mammon...

He needed...

He needed to get his family back...

Lucifer: For now on, I will make things right...Mammon.

*Later*

*Knock* *Knock* *Knock*

Mammon: Hm? I wonder who that could be?

He opened the door and his eyes went wide in terror.

Lucifer:.....Mammon.

Mammon did what his instincts told him upon seeing his older brother at the door.

*BANG*

He slammed it shut on Lucifer's face...
