i think exactly 2 people will understand this and they will be me and
@pseudonymphomania
i thought it'd also be fun to do betrayal scenarios for both but it accidentally ended up a bit more angsty than i'd intended whoops!!
i'll try to find time to draw out a good ending for them but i've been so busy this month :,D
happy day 1 of @pseudonymphomania’s dialuci week 2026 everyone!!
for the first prompt, secret relationship, I drew something semi inspired by that one chat where Lucifer was going to sneak Diavolo away to get fast food. I imagine Lucifer flying up to Dia’s balcony, but the two get a bit distracted before they can leave 🤭 also mini comic on the side because I will not miss an opportunity to put Mephisto in the cuck chair.
A private meeting to hide a secret date, all to hide a secret relationship (barb definitly knows, he’s just letting them get away with it this time). there’s layers to this shit!
The evening has arrived at Devildom. The RAD students are starting to go home, only those who want to work on their homework and the teachers are still there. Diavolo is at the head of this academy, so it’s natural that he finishes quite late despite his already busy schedule with his duties as a prince.
But it’s not a problem, not for today at least.
Barbatos gave him an hour of freedom -a rare thing-, so he intends to enjoy it with someone. Lucifer had texted him a few minutes ago, saying that he was in the lab classroom alone after helping Mammon and Asmodeus with their homework. Actually, "helping" is not really the right word to use, but rather "forcing" them to do their homework. These two demons are not known for their good grades, quite the contrary.
But well, school is not for everyone. These two excel in other specialties that are not academic.
As Diavolo arrives at the corridor where the classroom is, he sees Asmodeus and Mammon run away laughing. The Prince is sure that they must have played a prank on Lucifer, but certainly nothing bad since the Avatar of Pride does not pursue them. Without knocking, Diavolo opens the classroom door and sees Lucifer wiping his face tediously. Makeup and documents are scattered on his desk; would his two young brothers have put makeup on his cheek for fun?
"Lucifer? What happened to your face?"
“Asmo.” sighs the elder in annoyance. "I helped him with his makeup after he finished his homework, and that idiot kissed my cheek to thank me."
"It’s rather a cute thing, isn’t it?" says Diavolo with a smile. "You often complain that your brothers are not affectionate enough with you."
"I wouldn’t have complained if it wasn’t a cursed lipstick."
To show the reason for his annoyance, Lucifer stops rubbing his face to show his white cheek stained with a mark of pink lipstick. Diavolo gets closer to Lucifer, puts his hand on his cheek and tries to wipe the kiss print with his thumb: it’s no use. There is no burr, neither on his finger nor on the pale skin of the fallen angel. The only thing that Diavolo managed to do with his gesture is to make his lover slightly blush.
"Impressive. It must be Majolish’s new range of lipsticks, right?"
"Yes, and I need a special makeup remover." replies Lucifer. "Of course, this idiot left it at home! No matter how many spells I tried to hide my face, it doesn’t work.”
Lucifer sulks as Diavolo thinks, looking at the few lipsticks on the desk. So, that’s why the two demons were laughing. It was only for a cute prank. It changes from the traps of Belphegor and Satan.
Diavolo also wants to have fun.
He takes carmine lipstick and puts it on his lips, under the panicked gaze of Lucifer. Why does the Prince do that when he just told him this makeup is permanent without the right makeup remover? Lucifer doesn’t understand, but when Diavolo has finished putting on his lipstick, he can’t help admiring him and wanting to kiss him. If there is one person who knows how to put makeup on, besides Asmo, it’s the Prince of Devildom.
As Lucifer stares at him, Diavolo steps up and kisses his cheek. The fallen angel finds the act cute, until he remembers why he panicked a few seconds ago.
"Diavolo!"
The demon in red moves away from his lover to look at him with a cunning smile, the imprint of his lips now next to that of Asmo.
"I’m not allowed to kiss you? Only Asmodeus can?"
"That’s not the point!"
"What’s so embarrassing then? You’re my lover, everyone knows and I like to remind the whole world of it."
Diavolo smiles at him innocently before attacking Lucifer again with little kisses on his face, avoiding his lips on purpose. Although the Avatar of Pride is embarrassed, he does not really protect himself and even laughs at this "attack" from his lover.
But after about ten kisses, wouldn’t it be time to counter-attack? If the Avatar of Pride must go out with his face marked by love, then the Prince of Devildom too.
Lucifer asks Diavolo to stop by pushing him away, and he grabs a dark red lipstick. Before applying the cursed makeup, the Prideful demon licks his lips to moisten them and captivate the Prince. Diavolo looks at his man, with love and excitement. Seeing Lucifer’s face marked by his lips is gratifying, but watching him put on this cursed lipstick to kiss him is a real delight.
When Lucifer finishes, he puts his makeup on the desk and grabs Diavolo by his collar.
"Diavolo, lie down there."
“Yes!”
Excited by his partner’s enthusiasm, Diavolo lets Lucifer lay him down on a table. The fallen angel settles over him and looks at him with desire, Diavolo’s golden eyes shimmering.
Lucifer will devour him.
"You will pay for this affront, Diavolo."
"Show me then, Lucifer."
The Avatar gently approaches the Prince’s face, and kisses the corner of his lips. Diavolo lets himself go, the contact of the fallen angel relaxing him. He closes his eyes, sighing with ease at each kiss on his face. When Lucifer starts undoing his tie and whispers that his revenge will go further, Diavolo can’t help but moan in anticipation.
He loves it when Lucifer takes the lead.
Now that the neck of Diavolo is completely revealed, Lucifer kisses his lover’s throat. At first gently, only pressing his lips, then he becomes more passionate by tasting his slightly salty and hot skin, starting to chew it up and make hickeys. Diavolo ends up moaning when Lucifer licks his throat, making the Avatar of Pride smile even more.
Lucifer stops to look at Diavolo whose cheeks have turned dark red. He asks him to open his eyes and the Prince obeys: both are covered with kisses, the prints of their lips intact with the cursed makeup. Diavolo raises his right hand to put it on Lucifer’s cheek, where Asmodeus had kissed his brother.
There’s nothing better than a forest to hide a tree, isn’t it? Lucifer who didn't wanted being seen with Asmo’s kiss mark, now only Diavolo's love can be seen on his face.
"We match." says the Prince.
"For now." assures Lucifer. "But soon, your whole body will be covered by my lips."
"I’m waiting for that."
Diavolo keeps his hand on Lucifer’s cheek to bring his face closer to his own. Finally, their lips meet and kiss passionately, making their tongues dance and sticking their bodies together. Lucifer ends the kiss but does not let go of his lover’s lips, gently nibbling them.
As Diavolo tries to undress while Lucifer leaves his face to kiss his throat, they suddenly stop when they hear a door open abruptly. The demons turn to the source of the noise: behind them, Satan in his demonic form, petrified, while Belphegor is looking at them with disgust. They had hidden in the classroom wardrobe, with a can of paint to throw at Lucifer once his back was turned.
Unfortunately, they hadn’t foreseen that Asmodeus would prank Lucifer, much less that Diavolo would come shortly after.
And they didn’t expect any of this either.
"Satan? Belphie?" questions Diavolo.
"What the hell are you doing here?!" Lucifer gets angry.
The two young demons say nothing, paler than usual. Only Belphegor displays an expression of pure revulsion, while Satan is too shocked to express anything -although his demonic form betrays his feelings-. Without a word, the Avatar of Sloth takes his brother out of the classroom.
Upset, Lucifer leaves his place and glances at the hallway before closing and locking the door. Now, they are really alone.
"You... think they’re alright? They were very silent..." asks Diavolo timidly, seeing the anger emanating from his lover.
"I will punish them as soon as I get home." Lucifer says, taking off his gloves. "But before that, I want to finish what we started here."
The Avatar of Pride puts down his gloves and licks his lips. Diavolo swallows his saliva, Lucifer’s gaze more determined than ever.
"Undress." the fallen angel commands. "You too must be punished."
Lucifer is angry; not at Diavolo but at his brothers for ruining that moment. The Prince is more than happy to continue, especially with his lover who is going to be very passionate.

The Fantastic Three
Diavolo: Lucifer, were you able to clean your face?
Lucifer: The makeup remover from Asmodeus worked very well. For you too, I guess?
Diavolo: Yes! Even though I wanted to keep your love marks, Barbatos forced me to clean everything. At least, I took a few photos.
Barbatos: Young Master, you can’t go to bed with makeup. It's unreasonable, you know it.
Barbatos: And Lucifer, please, avoid using such makeup on Lord Diavolo in the future.
Barbatos:
Lucifer: Diavolo attacked me, I had to fight properly.
Diavolo:
Diavolo: I can’t wait to fight like that again, Lucifer.
Lucifer:
Barbatos: Enough. It’s time to talk about "that" now.
Barbatos: Lucifer, Diavolo, I am truly happy for you. That your relationship is so thriving and passionate is wonderful.
Barbatos: But I can’t go on like this.
Barbatos: Either I leave this groupchat and create a chatroom with only the Young Master, or you create one for both of you.
Barbatos: It’s "The Fantastic Three" here, not "The Lovers".
Lucifer: I understand. I’ll take care of it right now.
Diavolo: Barbatos, I’m sorry for embarrassing you so much with our discussions. I didn’t realize that we could be inappropriate here.
Diavolo:
Barbatos: It’s my fault too, I should have told you that since you are together.
Lucifer: Except that you wanted to be sure Diavolo wasn’t talking with me all night behind your back, right?
Barbatos:
Diavolo sighs, the message from Barbatos having concluded the discussion. Oh, he completely forgot to ask Lucifer about his brothers! He still remembers Satan who was completely frozen on the spot. As the Prince was about to go to bed, his D.D.D. rings and he sees a new chat appear, with only Lucifer and him.
The Royal Lovers (Lucifer, Diavolo)
Lucifer: Welcome to our chatroom, Diavolo.
Diavolo:
Diavolo: Thank you, Lucifer! Now we can talk freely here.
Diavolo: But I wanted to ask you something before going to bed.
Lucifer: Yes?
Diavolo: How are your brothers? You haven’t been too hard on them?
Lucifer: I gave a proper punishment to Asmo, Belphie and Mammon.
Lucifer: Asmo will have to do the dishes for two weeks, and I hung Belphie with Mammon.
Diavolo: Why Mammon? What did he do?
Lucifer: He knew about the cursed lipsticks and did nothing, so I punished him like the others.
Diavolo: And Satan?
Lucifer: It’s more difficult.
Lucifer: He hasn’t said a word since he got home. He went to lock himself in his room and when I entered, he was hiding under his bed.
Diavolo: To run away from you?
Lucifer: No, I think he’s still shocked by what he saw. I forced him out of his hiding place but instead of struggling or shouting at me, he was looking at the floor.
Lucifer: And then he went back to hide under his bed. I didn’t have the heart to punish him in that state, so I left him.
Lucifer: He didn’t even come to eat tonight.
Lucifer:
Diavolo: I hope he gets better tomorrow.
Lucifer: I hope so too, otherwise the others will become unbearable and blame me for his condition.
Diavolo: It will be fine, don’t worry.
Diavolo: But I think you need to use another approach with him. Why not discuss tomorrow, the three of us?
Yes, Satan will stay in fetal position all night. Yes, he tried to escape the discussion with Lucifer and Diavolo the day after. No, he couldn’t avoid it. (maybe I will write a part 2 with this lol)
Satan stopped trying to play pranks on Lucifer for a whole month and ran away from Diavolo as soon as he saw him lol
I hope to be able to write with the other prompts if I have time! <3 This is the first time I’ve participated in this kind of event! I was very inspired! ^w^
Some memes because I think it's funny. Satan and Belphie after watching their big bro and Diavolo doing "things" :
IT'S FINALLY DONE I FEEL SO HAPPY AND ACOMPLISHED!!!
Anyway~
This was written for the prompt: favorite AU but it includes other prompts in there sorta.
Anyway, yes this is my favorite au! I came up with it myself, and it's very special to me.
