Chapter Text
After the Great Celestial war, the six brothers were punished by being kicked out of the Celestial Realm and becoming demons… and children- specifically nine-year-olds, which they’re stuck as for decades before they’d be able to revert back to their true ages. Diavolo, getting soft-hearted upon seeing Lucifer’s adorable little self, has aided his dying sister in a new life as a human and given him, along with the rest of his brothers, a mansion to live in, all as long as he promised to do one thing… attend RAD in a special class with his brothers.
“...and promise me you’ll play with me every day-”
“Now, now, young Master, let’s not trouble him too much.” Seeing that the prince was getting too ahead of himself, Barbatos found that he had to step in, holding his shoulder to bring him back to his senses.
After decades of getting used to their new lives, the brothers became too comfortable. As in, at this very moment, the newest brother- Satan- is secretly in Lucifer’s room, planning to play another silly prank on him (which he always finds to be genius) by… emptying out Lucifer’s folded undies from his drawer and filling it up with his own, which he has brought in a laundry basket.
As the boy is filling up his drawer, he speaks to himself, “He’ll be all like, ‘Oh, where’s my undies? Now I have to wear Satan’s, oh nooo!’ Haha! That’s right, he’s the one that’s like me, I’m not like him! This is going to make him go through an undientity- I mean an identity crisis! Hahahahahaaa!”
His pranks are getting more absurd with each passing day.
Satan isn't the only one who likes to cause trouble for Lucifer, because later that night, Mammon had sneaked in and out of Lucifer’s room, believing that he has stolen something of value as he cheered in his own room, “I can’t believe I was actually able to sneak something out of Lucifer’s room! Heehee, I’m going to hang this on a flagpole and shatter his pride, that’ll show him for taking away my Goldie!”
And so, when the brothers arrived in front of the school in the early morning, Mammon was laughing obnoxiously beside Lucifer as he looked up at a flagpole, which usually has a RAD flag but now has been replaced by something else entirely. “Hahaha! Bahahaha! Lucifer’s underwear is up on a pole! Hahaha! H-hey, aren’t you embarrassed?”
“Not really,” Lucifer replies with a shrug.
“Haha- ah, eh…” His response sinking in, Mammon slows down his laughter and says with disappointment, “That’s not much of a reaction.”
“I mean, it’s not my underwear.”
“Ahaha, what do ya mean it’s not yours? You messin’ with me?”
Lucifer points up at the briefs that are flowing in the wind and explains, “Look, when you squint your eyes, you’ll see a name stitched to the end of it.”
Mammon squints his eyes and focuses near the hem of the briefs, noticing a stitched name in yellow that reads, "Satan". He instantly starts sweating bullets.
As if timing wasn’t on his side, he heard at that exact moment a furious growl from behind him, “Gaaaaaahhh! Who tied my undies to a pole?! Who did it?! Who?! When I find the culprit, I’m going to rip his **** and ***** **** *****!!”
Such grotesque threats have been redacted, for the Royal Academy of Diavolo does not approve of violent profanity from their elementary schoolers (which is seven students in exact).
“Unrelated, but I suddenly need a change of undies,” Mammon confesses, not daring to look at the furious demon behind him.
“You can use the one on the flagpole,” Lucifer responds nonchalantly, secretly amused by the whole thing. He turns to Satan as the boy was pulling at his hair, smiles, and mentions, “By the way, Satan, I see you’ve been using my drawer. Is this your way of saying you want to get closer to me?”
Satan growls in greater frustration, his face completely red at this point, before shouting, “Shut up! You little demon!”
“Yes? Quite so. Do you think before speaking?”
“Nnnnnnn!!”
Standing at the entrance of his academy and hearing Satan's screech from afar, Diavolo tells his butler, “Do you hear that, Barbatos? It’s the beautiful sound of a young boy cheering in excitement for coming to RAD.”
“Are you sure?” Barbatos questions. “It sounds like the cries of a choking bird to me.”
“Oh, here they come!”
As the prince wasn’t hiding his excitement with that huge grin of his, Barbatos quizzes him, “Now, Lord Diavolo, tell me, what did we go over when you’re greeting the students?”
“No hugging the kids and no trying to take them home with me, no matter how cute and precious they are…” Diavolo looks to the side and grumbles a bit as he continues, “...because, apparently, that’s kidnapping.”
“Drop the ‘apparently’.”
The brothers approach in a sloppy line with Lucifer being in front. Upon seeing him, Diavolo gets to his knees, opens his arms out wide, and cheers, “Luciii!”
Instantly, Lucifer stops in his tracks and holds a hand out, ordering as if speaking to a dog, “No! Behave!”
“Yes, sir.” Diavolo drops his arms, his smile dropping sadly along with them.
‘My lord, you’re getting scolded on proper adequate by a nine-year-old,' Barbatos thinks. It’s moments like these that make him just a tad bit worried for the future of the Devildom.
Moving on, Satan walks past Diavolo and stomps right back to him when he gets ignored. “Why would you offer Lucifer a hug but not me?! Do I not deserve one?!” he fumes.
“No, it’s nothing like that. I thought you wouldn’t want one-”
Satan cuts Diavolo off by challenging, “Like Lucifer?! Do you think I’m like Lucifer?!”
“I don’t! Here you go, Satan, I’ll give you a hug.”
Diavolo holds his arms out for Satan and the boy stands and stares for a bit before responding, “...I don’t want one.”
As if their exchange never happened, Satan casually walked inside the school and away from Diavolo.
Next came Mammon, who boasted as he walked past the open arms that Diavolo was offering him, “You gotta pay big cash if you wanna hug the Great Mammon!”
“You’re selling yourself?” Leviathan asks, walking right beside him and ignoring Diavolo.
“I mean, money is money, right? I think I’d make a lot.”
“...Do me a favour and stay away from succubi.”
After being rejected four times, Diavolo has the face of a sad puppy as he looked at Belphegor and squeaked, “Belphie…? Hug?”
Belphegor rolls his eyes and scoffs, “Pfft, come on, I’m too grown up for that.”
“I’ll give you a hug,” Beelzebub offers.
Diavolo grins widely when he finally gets a hug, happy enough to shed a tear as he hugs him back. Watching the scene, Belphegor waits for Beelzebub to leave before muttering, “...One hug is fine.”
“Awwww!” Diavolo awes when the small boy squeezes his short arms around his waist, hugging him back.
It was while he still had his arms around him that Belphegor realised Asmodeus was still there, the two making solid eye contact before Belphegor let go of Diavolo.
“Urk-! It’s just because Beel did it! I didn’t want him to embarrass himself alone like that! It was only because of Beel!” he throws out his excuses as he walks away, not wanting any of them to see his reddening cheeks.
“Ah…” Diavolo stumbles a bit as he watches him leave, feeling dejected and looking like he’s fighting to keep his smile.
“It’s okay, Mr Diavolo, I’ll give you a hug with all my heart!” Asmodeus comforts, giving him a hug and rubbing his cheek against his chest.
“You’re so sweet, Asmo!” Diavolo gleams.
“And a kiss!”
Diavolo lifts Asmodeus off of him and places him towards the entrance, responding, “Now, now, no physical contact with the students.”
“Very good, young Master,” Barbatos compliments.
