Dia Is His Son Wdym - Tumblr Posts

Barbatos, drunk and crying: I just want Lord Diavolo to be happy. His mother died and his father treated him horribly. It's my job to spoil him after I adopted him.

Lucifer: You didn't adopt him.

Barbatos: Yes I did. Here are the papers.

Lucifer: It's a drawing Diavolo made for you when he was a child.

Barbatos: That's when I decided he was my son.
