(unedited obviously)
You were being carried by Beelzebub to RAD, you were scared.
Since you were isolated a bit and the only Social interaction was with your mom, it's kind of scary meeting a lot of people at once.Soon you reached the entrance and Lucifer took you from Beelzebub.
"We'll be in the Assembly Hall if you need us."
Lucifer started to walk in the direction, before anyone answered. Y/n looks at all the students who passed them, some looking at them. Y/n hides her face in Lucifer's shirt.
~~~~Soon they reached the assembly hall and Lucifer set Y/n on the ground. She looked at the surroundings, staying close to Lucifer.
The doors soon opened to be 2 people.
The first person was a guy with dark red hair and yellow eyes. He wore a red uniform with a blue ribbon accent. He pairs it with a formal black shirt with gold button down collars as well as a neat white tie with a brooch underneath.
The other guy who was following him. He has short dark green hair with fridge reaching his eyebrows. The fridge on his left is longer, reaching his nose and has a turquoise ombre. He wore the same uniform as her siblings, but his top is a six-buttoned tailcoat. Under it, he wears a turquoise dress shirt and dark green tie. Instead of a belt, he wears a white cummerbund, also sports white gloves.
"Lucifer, I didn't expect to see you here this early!" the first guy smiled at Lucifer.
"Of course I would be here Diavolo" Lucifer replied. Y/n hid behind Lucifer still.
She gripped onto his pants slightly and looks at the 2 guys, one being named Diavolo.
The second guy had noticed me.
"Lucifer, who is the person behind you." He asks looking at Y/n who quickly hid behind Lucifer again.
Diavolo looked to see the dual coloured hair (H/c and white i forgot to mention it). She was still scared.
"Hello" Diavolo said trying to calm her nerves down.
She looks at them and hid behind lucifer again.
Lucifer soon managed to push her lightly forward towards Diavolo and Barbatos.
"H-hello..." she squeaked and looked at them. She played with her hair a bit.
"No need to be shy!" Diavolo said smiling at the girl.
"This is Diavolo the future king of the devildom." Lucifer said introducing him to Y/n.
"And this is Barbatos,my loyal butler" Barbato looks at y/n.
"Nice to meet your acquaintance."
"This is Y/n, she is my sister." Lucifer said, he knew y/n would be too scared to say anything.
Diavolo's eyes widened "I never knew you had a sister... except for Lilith..."
"We adopted her 2 days ago..." He said looking at the girl in the corner of his eye.
"Well it's very nice to meet her."
Soon the bell rang signalling that class started.
"You both should get going, she can stay with you for your classes today, oh and we can get her a uniform" Diavolo said grinning.
Lucifer sighed a bit and nods. He starts to head off with Y/n following behind him.
