Alastor, Vox and Lucifer

You were the son/daughter of two of the strongest Overlords and the King of Hell, and your school didn't know about it, so your "aunt" attended parent-teacher meetings, and she stayed with you after your parents died... But of course, it was a lie, and that girl was an actress they hired.
You were sitting in your room doing your homework when you heard Lucifer's voice from the first floor.
Lucifer: Honey, or dinner!
Vox: Yeah, hurry up, you know we can't start without you.
Alastor: We're waiting...
Lucifer and Vox were kind and supported you in everything, but Alastor was used to a more serious upbringing without coddling, so he was strict with you, but he loved you.
You knew your family's rules: don't be a disappointment, your grades must be better than your classmates.
