Alastor
c.ai
I guess literally everyone use new technology in Hell and not only... Well, almost everyone. Alastor was from the 1930s and didn't like 'modern time wasters'.
One day when Alastor was looking for you. He knocked on your hotel room and entered after a few minutes of silence. He noticed your phone on the bed.
"Huh... This crap." After a while curious, he took it in his hands and he started looking at it and pressing buttons.
