[A/n: Finally, part three is ready!]
"Belphie's coming to the human world?!" You asked.
"He's putting himself in danger! My brothers might follow him here!" Said Beel.
You started shivering in fear. "I don't want him to get hurt because of me!" You cried.
"He said not to go anywhere until he gets here, so there's no point in hiding somewhere else." Said Beel.
"I'm really worried now!" You gasped, "Why is he coming here?!"
"He didn't say." Said Beel, "Please calm down!"
You were worried sick about this. Why is Belphie coming to the human world? What risky reason is prompting this? "You should probably get some rest." Said Beel, "You look uneasy."
"Because Belphie is probably putting himself in danger!" You said.
"I'm worried too," said Beel, "but he wouldn't come unless there was a majorly important reason."
You were still quivering. Beel put out the fire and took you into the cave. You ran to the very back and curled up in a ball. Beel joined you as well. The inside of the cave was very cool, but you still were a little chilly. Beel laid you on the sandy ground and he cuddled with you. "Just remember," said Beel, "I'm here for you."
"Thank you...Beel." You whispered in his chest, falling asleep.
[In the Devildom]
Lucifer was now very annoyed. "Where has Belphie gone now?" He grunted to himself.
"Lucifer, what's the matter?" Asked Asmo, "From the look on your face, something happened!"
He sighed and said, "I cannot find Belphie anywhere. I haven't seen him since yesterday."
"Belphie's gone missing?!" Exclaimed Asmo.
Lucifer's D.D.D started ringing. He was getting a call from Diavolo. "Yes, what is it my Lord?" Asked Lucifer.
"The blood drive that happened yesterday..." Said Diavolo.
"What about it?"
"The doctors went to check on the samples of you and your brothers, but something happened to the blood!"
"What happened?!"
"All of the samples are rotten!"
"What?!"
"Apparently, someone opened the bags and either stole a sample or drank it. Not much was taken, but the donations are now useless."
"What kind of monster would do such a thing?!"
"Has anything happened lately?"
"Lately...! Belphie has gone missing!"
"Belphie?"
"Yes. I haven't seen him since yesterday after the blood drive."
"My guess is that he is the one who stole the samples."
"What makes you say that?"
"One of the viles of golden reversal syrup has gone missing."
"What does that mean?"
"The mix of blood from seven demons and golden reversal syrup is said to make an antidote for a human who turned into a demon. And that could lead to a lot of problems."
"So you're thinking Belphie went to find (y/n) to turn her back into a human?"
"I imagine so. Find him, and do not let (y/n) drink that mixture!"
"Understood my Lord."
Lucifer hung up, and became furious. "What happened?" Asked Asmo.
"I'm going to find Belphie. I know what he's planning on doing." Said Lucifer angrily.
"Oh my!" Exclaimed Asmo.
[The next morning in the human world]
You and Beel woke up, and you were both covered in sand. Your stomach rumbled in hunger. "I'll go find some food." Said Beel.
You stayed inside the cave and waited. You barely saw the morning sun since people come to the beach in the morning. It would have led to you devouring human souls. And just by your pointy teeth, people would mistake you for a monster. You looked into a cracked mirror and saw your pointy teeth. Next to it was a file. A rough surface...
[Time skip]
Beel ran back into the cave with a sea urchin. "There's too many people to do a lot of hunting so...!"
Beel paused as he saw what you did. You groaned as you filed down your sharp teeth to look like normal teeth. Once your teeth were rounded, you put the file down. "Now I won't look as fearsome." You said.
"Your teeth!" Gasped Beel.
"I kinda decided to get rid of the sharp teeth." You said.
"I can see that," said Beel, "but you really shouldn't do that to your teeth! They could have gotten damaged!"
"Maybe now I won't look like a monster in front of the humans!" You said.
"But you could still lose control and wind up devouring someone's soul!" He said.
"I've been trying to learn to control myself!" You said.
"(Y/n), I know not coming out of the cave is hard, but it's the only way to keep you safe. If Lucifer or Diavolo come here and find you, they'll take you away again." Said Beel, "And I don't want that to happen again."
You paused. He's really worried about you. You didn't want to disappoint him so you said, "I'm really sorry. I didn't think you cared so much."
He stooped to your level and gave you a hug. You hugged him back in response. A buzz came from Beel's D.D.D and he got a message from Belphie.
Belphie: I'm coming earlier than I thought. Stay where you are and do not go anywhere!
-End-
"Belphie's here already?!" Asked Beel, shocked.
"He said he'd be here in three days! He's earlier than I thought!" You said.
"Well he has come here quite a few times, so I wouldn't be surprised if he found quicker ways to get here!" Said Beel.
Oh yeah, he has gone to the human world a lot. "Guess we just have to stay here until he gets here." He added.
[Time skip]
After an hour, someone was at the entrance of the cave. "Belphie!" Cried Beel.
Belphie gave a warm smile to his twin, and he gave him a hug. Belphie saw you curled up at the far end of the cave. "How's she doing?" Asked Belphie.
"She's doing good. She almost damaged her teeth though." Said Beel.
"How?"
"She tried to make her fangs look like her normal teeth so she'd look less fearsome towards humans."
"Has her craving for human souls talk to her?"
"Yeah. So I only let her out once there are no humans on the beach. And that's after sunset."
"Poor (y/n)." Said Belphie, "Luckily, the wait for socialization is over."
"Why's that?" Asked Beel.
"I have a potential cure for her!"
"A cure?!" Gasped Beel.
"Yeah. I just need a few drops of your blood, Beel."
"Why do you need my blood?"
"Because an elixir made from the blood of seven demons and golden reversal syrup can turn her back into a human again."
"Will it work?"
"I saw that for better results, we should use the power of the demon king and his lineage, but I don't think Lord Diavolo would be much help to us. So the syrup is our only hope."
The twins walked to the back of the cave where you were sitting. You saw Belphie and you both hugged. "Why are you here?" You asked.
"Don't worry," said Belphie, "You'll be a human again soon!"
Beel still looked concerned. Belphie grabbed a blade buried in the sand and he said, "Beel, your blood."
Beel was silent and had a look of discomfort. "..."
"I know you dislike pain, but you gotta do it for (y/n)." Said Belphie.
Beel looked at you and said, "(y/n), can you hold my hand?"
You smiled. You laced your fingers into his and Belphie cut a small slit in Beel's finger, allowing Belphie to get a few drops. Belphie added some blood samples to a small gold vile and gave the vile a shake. After he shook it, he handed you the vile and said, "Down the hatch, (y/n)!"
Holding the gold vile, you looked at it nervously. "Will this really turn me back into a human?" You asked.
"Don't you trust me?" Asked Belphie.
If you drank it, you'll be human again? Still holding Beel's hand, you put the vile to your lips, only to hear a voice say, "Stop right where you are!"
You and the twins looked to the cave entrance and saw a figure there. "Lucifer!" Gasped Belphie.
