Imagine...

... celebrate your birthday in the Demon Realm

You crossed out number 15 on the calendar. Your birthday had finally arrived. This time it would be the first time you would spend your birthday away from home, in the Demon Realm. You missed your family and friends a lot even though they almost always forgot about your birthday, sometimes even forgot about your gifts. This time it would be no different, you had not told anyone that "special" date, it would be one more day of school. You left your room, feeling a wave of heat hit your face. It was very hot, it was normal to be mid July. You hated the heat, it was very sticky as opposed to the cold in which you only had to put on one more blanket to be fine. On the other hand, in summer you couldn't tear off your skin. At least wearing shorts and a tank top helped a lot. The advantage of this institute is that in the summer they were more permissive and did not force the students to wear the heavy uniform they wore the rest of the year. After going through several corridors you came to your classroom.

-____ - Mammon got in your way, preventing you from entering the class- Diavolo has called you to his office. I don't know what trouble you've gotten into but you'd better hurry up.

"What?" - you thought surprised. The past few days had been extremely calm, not even an accident with Mammon or Levi had happened. You hadn't skipped any class, either. A bad feeling invaded your body as you knocked on the door.

-Pass

You entered. Your steps were slow and your legs were shaking a little. You felt very nervous, as if you had killed someone and he knew the truth. But you hadn't killed anyone, you hadn't even hit Beel when he stole your chocolate.

"Sit down," Diavolo ordered. His voice sounded deeper than usual. You'd hardly come across the devil a few times. You had seen him speak to Lucifer from a distance but now that you were much closer his appearance was a thousand times more intimidating. He was much taller than you, he passed you two or three heads (damn half a meter, at his side you seemed tiny). He was also in his demon form, revealing his muscular arms and his body worthy of a Greek god rather than a prince of hell. This was not the time for that kind of thinking. You obeyed, sitting across from him. Your heart was racing because of nerves, pounding inside you.

-I suppose you know why you're here- his inquisitive gaze fixed on you. There were no longer faces of that serious but affable demon that you saw from a distance.

- Is it because of my clothes? If it's not appropriate I can change it right here- you stammered with downcast eyes. "Change it right here? In front of him? Damn brain, always playing it in the worst moments. Now you were even more nervous and embarrassed.

-No, the regulations are very flexible for those questions- he replied with a sigh, a sigh too long for your liking- Your behavior in recent days has been unacceptable. Today you will not attend your classes, you are expelled.

- B ... but I haven't done anything, sir. I have attended all the cla-

-Do you have any objection? I have been benevolent since you are an exchange student. Any normal student would be expelled all week- his tone denoted disappointment and sadness despite the fact that a mischievous smile formed on his face- Unless you want a more severe punishment, of course

- No ... not of course not, sir- your cheeks turned even redder imagining all kinds of punishments. Great, often a birthday was waiting for you locked in your room. You hadn't even had time to greet Lucifer and Asmo.

"That's all, you can go," he sentenced looking at the door. You got up, heading towards the exit, feeling his intense gaze behind you- By the way excellent choice of clothes, ___

Once you were out of the room, you ran completely flushed, drawing air with all your might. You didn't expect Diavolo to possess that so ... "magnetic" aura. Still the news had been lousy, you were kicked out and you didn't even know why. Nor did you feel like arguing and taking a worse punishment. On the way to your bedroom you met Asmo, who was waiting for you at the door. At least it was a familiar face.

- Hel-

-I'm sorry ___- you heard Asmo's voice before feeling a strong blow to the nape of the neck and falling unconscious to the ground.

---------------------------------------------

You didn't know where you were, you couldn't even see. You were tied from head to toe in a moving place, perhaps a car. It is done. They had fed up with you and sold you to a local mob. Or maybe they would auction you off on the black market. Maybe it had been Sangwoo and you were going straight to his basement ... Too much time reading. While those surreal ideas ran through your mind, the place where you were stopped. Well, it had been pretty while it lasted. What sadness, to die the same day of your birth. You hadn't even said goodbye to your father or your friends. You felt like arms grabbed you, pulling you out of wherever you were. They walked you for a few minutes. Finally you felt a hand brush your face, reaching up to your eyes to carefully remove the bandage. You opened your eyes, afraid of what could be ...

-HAPPY BIRTHDAY _____!

Before you was a large group of people, among whom the brothers, Simeon, Luke and Diavolo stood out. You could not contain a cry of joy when observing the party that had been prepared for you. They had decorated a garden with many flowers and balloons, the pool was full of crystal clear water and a huge banner with your name was hanging between two trees, next to the largest cake you had ever seen, of about 7 floors. You would never have expected something like this, much less from them. You reached out to them, hugging them.

-Thank you guys ...- With a wide smile you wrapped yourself in a warm hug. How did you know it was my birthday?

-It was easy, Lucifer warned us. Your birthday was in your file- Asmo answered- And then we decided to surprise you all.

- Bel and I take care of the decorations- added Satan- While Belphie was dedicated to preparing the cake.

-Hey Hey! but the most important part was done by me- Mammon protested pouting- I was the one who brought ____ to the party

"You mean that you were the one who hit me and dragged me in a dark van here?" Scary- you joked making Mammon depressed.

"Mammon thats not the way to conquer ___," added Bel.

-Hey ... And Lucifer? - You asked a little worried when you didn't see him in the crowd- Didn't he come?

"Regarding that... better forget about him and eat the cake," Belphie pointed at the table.

You walked up to where Belphie was pointing and then something happened you didn't expect. Lucifer came out of the huge cake in a playboy bunny costume. His serious and embarrassed gaze locked on you, seeking a reaction. For your part, a thread of blood gushed from your nose while your face was already completely red.

-Thank God for giving me such fantastic friends

"I remind you that they are demons," Simeon murmured.

"I was going to go to hell anyway so..." You shrugged and then go back to Lucifer and give him another hug, making Mammon almost throw him a chair.

No doubt you had found a "family" in that place. They were all special and cared about you. They had not forgotten your birthday and always tried to surprise you and make you enjoy yourself. Whatever happened you would have them. And that was without a doubt the best birthday gift you could wish for.

-And now ... Let the party begin!

RETURN THIS TIME WITH A NEW CHAPTER!

The truth is that I wrote it a long time ago and I just had to finish it, but hey, its something. I wanted to try something more general and not so much of romance. I hope there are fans who like Diavolo, the truth is that I love it and it is very underrated.

(Although if it were up to me I would write about 50 shades of Diavolo, Lucifer and Satan but there has to be diversity)

I hope you liked it even if it's not my best one-shot.

Thanks for reading, see you soon!
