Hold on, Who's Mammon?

Jealousy

"You will be shown around by me." Lucifer announced. Immediately, He was hit by the jealous brothers. "What?! No, He'll be shown around by the best person here!" Asmodeus huffed. "Stupid old hag." Satan muttered under his breath. The twins simply looked hurt.

"What about Leviathan?" Diavolo asked with wide eyes. "But Diavolo-" Lucifer began, but Diavolo raised a brow. "You cannot defy me, Lucifer." Diavolo refuted. Lucifer bitterly looked down, furrowing his brows. "You will be guided by Leviathan, Avatar of Envy and the third brother." Diavolo smiled.

"Lucifer, give him your D.D.D." Diavolo commanded. Lucifer frowned, handing Marco a phone. "A phone?" Marco scrunched his nose. "It's called a D.D.D." Lucifer corrected, holding one finger up. Marco nodded, understanding. "Here, this is the ON button." Lucifer showed him the mechanics.

Upon opening the phone, He saw a SIRI-Like AI talk to him. It's concerning, He could hear the voice in his mind. "I AM KARASU! WELCOME, USER MAMMON!" Karasu echoed through his head. Marco squinted his eyes, dumbfounded. "I SEE YOU ARE USING YOUR BROTHER'S PHONE YET AGAIN." Karasu robotically spoke.

'Brother? Mammon? Huhh.. Another brother other than Leviathan or whoever that dude is. Beel- BEELZEBUB! called me Mammon. They're seriously mistaking me for their brother..' Marco thought in his mind, deadpanning. He scrolled to the contacts. 'Thinking 'bout this Mams dude, why're they even mistaking me for 'em.' He thought.

Pressing on Leviathan's avatar, He put the phone to his ear. Immediately, The call was accepted. "Sheesh! I told you, Lucifer! I didn't want to go to the stupid student council meeting! I don't care about Humans!" Leviathan screamed through the call. "Um.. I ain't Luci." Marco mistakenly called Lucifer what He used to call him way before. Lucifer's eyes widened, gaping.

The line was silent for a while. "....Mammon?" Leviathan's voice became softer, more earnest. "I ain't Mammon. 'M Marco." Marco huffed. After learning they think of him as their brother, it made him bitter. He doesn't want to pretend to be a random dude, even worse when it's their brother.

"....I'm coming." Leviathan muttered, and Marco heard footsteps over the call. "Don't hang up the call.. Please.." Leviathan begged. Marco blinked. Were these demons really that desperate for a random demon brother? Jeez. "Like I told ya, I ain't Mammon." He scoffed. Leviathan did not respond.

In about 2 minutes, Leviathan was there. "Explain, Lucifer." His words were coated with seriousness, which was weird for his chara- Wait, How do I even know his character? What the hell is happening? Was I transmigrated or something? Oh my Diavolo.. wait, when did I ever joke like that?

"I.. I don't know myself." Lucifer admitted, dumbfounded. "Ha, The old hag admits it." Satan snickered, though confused himself. "Hehe.." Belphegor giggled. Lucifer glared at them, a purple aura surrounding the black haired demon. "You don't scare us." Belphegor replied to the hateful stare.

Diavolo sat comfortably in his seat, already knowing who Marco was due to Barbatos. "Leviathan, you are tasked to show Marco around the House of Lamentation." Diavolo piped up. "Thank you." Leviathan muttered. He grabbed Mam- Oh, I mean Marco's hand and ran out of the room.

"Oh come on! Why Leviathan! This isn't fair.." Asmodeus pouted. "Lord Diavolo, Why have you chose.. him?" Lucifer smiled bitterly. "Oh come on, 'Chill out' or whatever those humans say!" Diavolo heaved a sigh, a sad smile on his face. "After all, He isn't Mammon, right?" Diavolo grinned a toothy grin.

Belphegor held an 'are you serious?' look on his face. After all, He already knew it was Mammon. He was sure of it. He knows it. The bluenette grumbled. Beelzlebub, who trusted his twin, looked hurt. He narrowed his eyes and sat down. Asmodeus furrowed his brows, and huffed. "I know He isn't... but.. still.." He sniffed.
