Y/N's POV
"Woah!" I moved out of the way as a mountain of books came tumbling down next to me.
"I told you to be more careful." Satan shook his head.
"Maybe you could clean your damn books up more often." I sighed as I picked up a few books.
I had agreed to help Satan organize his book filled room, but it was a huge challenge with so many books around.
"Why didn't I ask to clean someone else's room? Like Belphie's and Beel's room! Well, I would be distracted by-"
"Hmm? This book looks weird." A single book stood out from the rest.
It had a light blue cover, and caught my eye immediately. I picked it up, and I was blinded by a white light.
3rd POV
Satan had noticed that Y/N had gotten quiet, so he turned around to look at her.
However, she was nowhere to be found.
"Y/N? Where are-?" Something tugged at Satan's pantleg.
The blonde demon look down to see two large E/C looking up at him.
"Why you big?" She cutely tilted her head to the side.
"Oh my Devildom....Y/N, is that you?" Satan was dumbfounded. How did she get so small?
"Yep!" She grinned. Satan noticed the book that the little girl was holding.
"Y/N, can I see that book please?" She nodded, and held the book up.
It only took one glance for Satan to realize what had happened. He sighed.
"Come on Y/N. We need to have an emergency meeting." She tilted her head to the side.
"Eme.....emermeny meeting?" Y/N tried pronouncing the word, but she had some trouble.
You see, she still kept her memories of the brother. Though her brain was like a child's.
She didn't understand big words, and didn't realize what she had exactly done.
"Heh. Yes, let's go." Satan said as he walked out the door.
The little girl tried her best to keep up with Satan as he briskly walked as he texted his brothers.
When they got to the living room the brothers were already waiting for them.
Y/N started thinking that what she did was bad. Like she was going to get in trouble.
So she stayed outside the room and peeked in front the doorway.
"What's the emergency?" Lucifer asked.
"Well, Y/N asked to help me clean up my room. She accidentally touched a cursed book..." Everyone tensed up.
"Y/N can you please come in here?" Satan looked at the doorway as the little girl shyly walked in the room.
She was looking at the ground, trying to avoid eye contact with anyone.
"Wha?! She's a kid now?" Mammon exclaimed.
"Only temporarily. The curse should wear off in a day or so." Satan explained.
"I sowwy...." Y/N spoke in her small voice.
"Aww it's fine because you're so cute! Come here Y/N." Asmo kneeled down.
"No! She's too moé! You'll taint her!" Levi cut in.
"I'm not Moe. I'm Y/N." She responded cutely.
"Hehe. You are pretty cute Y/N." Belphie spoke up.
The moment Y/N looked at Belphie she darted over to him. She climbed on the couch and hugged him.
"Hugs!" She nuzzled Belphie's chest.
"Looks like she likes you Belphie." Beel chuckled.
"Mhm. Wanna stay with Bephie today." She smiled.
"Well, that settles that. Belphegor is in charge of watching Y/N until she's back to normal." Lucifer stated.
"Yay!" Y/N celebrated.
A little grumbling noise came from the little girl's stomach, and she blushed.
"Do you want something to eat Y/N?" Belphie asked. She nodded.
"Well it is almost lunchtime. Let's head to the kitchen to find a snack for you." Beel ruffled the girl's hair.
"Oki." She got off Belphie, and everyone started walking to the kitchen to look for something to snack on.
Unfortunately, Y/N was falling behind. Everyone in her eyes were walking super fast.
"Do you want me to carry you Y/N?" Belphie turned around, and the girl nodded.
"Thank you Bephie." She thanked him.
They got to the kitchen, and Beel handed Y/N an apple. She looked at it curiously.
"Too big..." Lucifer chuckled and took the apple from her. Belphie set her on the ground.
He quickly cut it up into little slices and put them into a bag. He handed her the bag, and she ate a slice.
"Yummy." She said as she ate another slice.
Everyone else found something to munch on as well. When Y/N got down to her last apple slice, she looked up at Belphie.
To get his attention she tugged on his pant leg softly. He looked down to see her holding her last apple slice up.
"Bephie, say ahh." Belphie chuckled as he kneeled down.
"Ahh." He decided to humor Y/N and est the slice. She fed it to him.
What she did next was somewhat surprising. She took the empty bag to the trashcan, only to realize she was too short to put it in.
She tried standing on her tiptoes, but even then she couldn't reach the lid. Levi opened the trashcan for her and she tossed it in.
"Thanks Levi." She smiled up at him.
"No prob. Oh shoot! The raid is going to start soon!" Levi dashed away, leaving Y/N confused.
"Where Levi going?" She asked Belphie.
"Probably to play some video games." Suddenly he yawned, causing Y/N to do the same.
"Looks like she's tired." Lucifer pointed out.
"Wanna take a nap Y/N?" Belphie picked her up.
"Mhm." She was already resting her head against him.
So Belphie carried her to his room, and he laid down with the little girl already drifting away in his arms.
"She is cute. As a child, and as her normal self."
Belphie thought to himself as he fell asleep.
-time skip to a few hours later-
Belphie slowly opened his purple eyes and glanced around the room. Beel was nowhere to be found, so he assumed that his brother was eating.
He heard a cute mumble, and he looked down to see that Y/N was still fast asleep.
"She's too cute for her own good. Maybe I should tell her when she turns back to normal.
Should I tell her that I love her? Will she return my feelings? She might think of me as a friend, or even a brother figure.
But....I should still tell her. Just to get it off my chest. Even if she still thinks of me as a brother figure, I'll do my best to make her happy."
Belphie softly placed his hand on Y/N's head and started stroking it. She murmured a little, which only added to her cuteness.
She opened her eyes to see what was touching her. When she saw that it was Belphie she nuzzled his hand.
"Good morning." Y/N rubbed the sleep out of her eyes. She looked around the room.
"Where we at?" She was still half asleep.
"We're in my room. Did you sleep okay?" Belphie asked as he kept stroking her head.
"Mhm..." Just then, the door to the room opened, and Beel walked in.
"Hey Beel. Were you off eating?"
"Yeah. It's almost time for dinner. I came to wake you guys up." Beel was already leaving the room.
"Don't wanna move." Y/N whined.
"Heh, I'll carry you again." Belphie sat up and carried Y/N to the dining room.
The entered the room, only to see that everyone had already started eating. They looked up.
"Did you two enjoy your nap?" Satan smirked. Y/N nodded.
"Are you hungry Y/N?" Lucifer asked.
"Mhm." She nodded again.
Lucifer set down small bowl with mac and cheese.
(A/N idk if they serve human food regularly in the story, but whatever)
"Yay!" Belphie set her down, and she cautiously ate her food. She knew it was hot, so she blew on it before eating.
It didn't take long for everyone to finish their food, and the demons left to go do whatever.
"Bephie, can you take me to my room?" She asked politely.
"Sure, what for?"
"Pajamas." She was still kind of tired from her nap, and it was getting a little late.
"Alright. Let's go." Belphie picked her up, and took her to her room.
She opened her bag and grabbed her large pajamas and went in the bathroom to change.
When she opened the door she nearly fell over. He pajamas were huge on her now, and she could barely walk.
She got onto her bed, and got under the covers.
"Bephie....can you stay here?" She asked cutely.
Belphie was slightly shocked for a moment, but then nodded. He got on the bed with her.
"Hey Bephie....I have secret." She mumbled.
"What is it?" He asked.
Before he could get his answer, he noticed that Y/N had already fallen asleep again.
He chuckled, and covered her up with the blanket. He decided to stay in the room like she had requested.
Y/N's POV -middle of the night-
When I opened my eyes, I noticed that it was pitch black in my room. I glanced down, and noticed that I was back to normal.
"Oh thank goodness! Being a child again was so weird, and I almost confessed my feelings to Belphie!"
My cheeks turned red as I recalled the memories of today.
"You're normal again." Belphegor suddenly spoke.
I whipped my head and saw that he was sitting at the edge of my bed.
"Y-You actually stayed in here?" I nervously asked.
"Yeah. You asked me to." He smiled nonchalantly.
"But that was little me talking, so why did you stay?" He got up, and moved closer to me.
"Y/N, I have a secret to tell you." His face was inches from mine.
"W-What is-?" He leaned in, and kissed me.
It was a soft, yet tender kiss. I melted into it.
"I love you." He whispered.
"Love you too." I responded.
(I know I know, kind of a crappy ending. I tried lol. Anyways, I do want to say something.
I won't be doing the extended Beel and Satan one shots. It's a lot easier on my brain.
I'm sorry if you were expecting them, I'll try to do an amazing job whenever we hit 3k views to make up for it)
