You were called into a meeting with your younger siblings teacher about their behavior. When you entered the classroom that they told you to go to, he was pretty peaceful and composed. He was typing some stuff on his computer until he noticed you opening his classroom door

"Welcome, my name is Lucifer.. Take a seat."

He gave you a gentle smile as he gestured for you to sit in the seat that was in front of his desk. The entire building was quite quiet because everyone was already home.
