Secret (demon brothers x idol reader)

Y/N's POV

"Please Diavolo. This would mean a whole lot to me. I'll do anything!" I begged as I looked right in into the prince's golden eyes. He was silent for a while, making me more and more nervous.

"Well, I can't say no to that face. But please keep up in your studies when you have time. Of course, I do hope you'll get us all tickets." Diavolo winked at me, and I felt like crying out of happiness. I reached into my pocket, and pulled out nine tickets.

"I already prepared them. I was going to use them as a last resort to convince you to let me go. If you don't mind, I have a condition.

Please don't tell the others. No one's supposed to know my identity, so it's kind of important. Plus, Lucifer would be annoyed if he finds out about this." I chuckled. Diavolo nodded.

"I will take you to the human world in a couple of hours, so please get ready. I will inform the brothers about what is going on. I'll call it a "family matter" so they don't get suspicious."

After we finished talking, I hurried back to the House of Lamentation to go and pack my suitcase. I was going to the human world for a very specific reason: I was an idol known as Nijiko, meaning "rainbow child" in Japanese. I'm debuting a new song in a couple of weeks at a live performance.

The reason I don't want to be seen is because I know how crazy fans can get. They could potentially find out who I am and where I live or anything like that. No one but my manager and the people I'm working with actually know what I look like.

I always wear a different contact color for every performance. It usually matches whatever outfit I'm wearing. I also wear a wig that also matches my outfit. Since I've worn so many different colors in my performances, the name Nijiko is an extremely fitting name.

I decided to listen to the song on my MP4 with some headphones. I had recorded it for the first time before coming to Devildom, but it's taken a lot of effort to reserve a stage for my performance, so it's been a while since I've listened to it.

I started subconsciously humming along to the familiar sound of my voice as I packed up my bag. It was a little odd hearing my own voice, but it wasn't a bad thing.

3rd POV

"What?! Why does she gotta go to the human world for?" Mammon inquired. All of the brothers had assembled at Lucifer's request. He had received a text from Diavolo, telling him that Y/N had to go to the human world for a couple of weeks for personal reasons.

"Aww~ but that's so long! How will she last without me being around her?" Asmo pouted. Everyone rolled their eyes at Asmo's narcissistic thought.

"I didn't ask. Besides, if it's something personal, then we don't have the right to ask Y/N about it." Lucifer spoke in a serious tone. Everyone knew he was right, but their curiosity was eating at them.

"Screw it! I'm gonna find out!" Mammon turned around and ran out of the living room, causing the others to chase him and try and stop him. If it weren't for Y/N's headphones, she could've heard them a mile away.

Mammon was going to slam her door open, but it was already open. They all stopped when they heard Y/N humming along to some kind of music. She was also packing things into her suitcase.

The song was pretty catchy, even without any lyrics. None of the brothers could say that they've heard the song before. A couple of them were curious about what the song was called.

"Yo!" Mammon tapped Y/N on the shoulder, and she jumped back, obviously startled by the demon.

Y/N took out a little electronic, and then pressed a button. Then she took off her headphones, and gave the brothers curious looks. She was wondering why they were all inside her room.

"What are you guys doing here?"

"Mammon wanted to know why you're going to the human world. We couldn't catch up to him in time." Satan explained. Y/N tensed up a little bit, and Lucifer noticed it immediately. So he glared at Mammon, who tensed up himself.

"Just ignore him, Y/N. I guess we can say goodbye now since it looks like you're almost done packing." Belphie walked up, and hugged the human. She gladly hugged him back. All of the brothers had said their goodbyes, and Diavolo came to pick Y/N up.

Y/N's POV

"Nijiko, you're on in 15." One of the directors said, and I nodded my head silently. I looked at myself in the full-body mirror, and chuckled. I had a lot of red on.

I was wearing a red cosplay wig with red contacts. I also had on a red sleeveless dress that was pretty loose, which makes it easier to move around.

I spent the next fifteen minutes preparing myself for my performance, feeling a mix of anxiety and excitement.

3rd POV

Diavolo, Barbatos, and the seven demon brothers were standing near the front of the stage, waiting for Nijiko to come out and perform.

"Nijiko is debuting a new song tonight. Isn't that exciting?" Diavolo asks the brothers. Levi nodded with enthusiasm. This was a rare occasion when Levi wasn't acting as shut-in as usual.

"Totally! I looked her up this weekend, and she has so many good songs! Too bad Y/N couldn't come and see this."

A man came on stage, and announced that Nijiko was coming on stage. The crowd roared as she walked on stage. She made her way to the center, and she waved to everyone in the crowd.

"Why isn't she saying anything, and why is she wearing all of that red?" Satan whispered to Levi. He sighed, as if everyone should know the answer to that question.

"You're such a normie! It's because she doesn't want anyone to know her identity! She doesn't speak normally! As for the cute outfit, she wears a different color each performance to hide her identity."

Soon, the music started playing. It sounded pretty upbeat, and the girl on stage started nodding her head along with the beat of the song. People in the crowd started clapping along with the beat as well.

The girl began singing, and the crowd got quieter to listen to her voice. She looked extremely focused as she sung by herself on the stage, as if the world around her had faded away, and it was just her and her voice.

The brothers widened their eyes slightly. The song sounded a little familiar to them. But how could that be? This was the first time that the song had been heard by anyone. So why did it sound familiar?

Nijiko happened to glance in their direction, and noticed that they were staring at her. She smiled as she turned back to face the front of the stage. Levi started freaking out.

"She looked at us! OMG THE Nijiko looked at us! She smiled at us too!"

As the song went on, the brothers were slowly remembering where they had heard the song before. They all looked at each other as they realized where they had heard the song before, and then they looked back at the girl on stage.

She looked like she was having more fun than she did a few moments ago. She was positively beaming as she continued singing the song. She was swaying now, her pigtails were swaying around with her.

Y/N's POV

"Hey guys! What's going-?" As soon as I stepped through the doorway of the manor, all of the brothers were looking at me intently. I felt a chill down my spine.

"Y/N, I believe there is something you need to tell us?" Lucifer broke the silence. I felt extremely nervous.

"W-What are you-?"

"You're Nijiko?!" Levi exclaimed. It felt like a bucket of cold water was just poured over me. My suitcase fell to the floor with a thud. I looked down at it because I couldn't look any of them in the eye.

"H-How did you know?"

"You were humming the same song before you left Devildom. You also smiled at us on stage."

"I-I'm sorry..." That was all I could say. A few moments passed before I felt someone hugging me. It was Beel. The others surrounded me as well.

"Whaddya sorry for?! That song was awesome!" Mammon said with his usual grin. The other nodded in agreement.

"I understand why you had to keep it a secret, but next time you don't tell us something this important, there may be consequences." Lucifer said in a serious tone. I nodded quickly.
