[Lucifer is, of course, taking his participation in this very seriously. Work is important, afterall! Or maybe it's just that he gets to dress up in a beautiful red kimono and drink sake all day long.... which is what you'll find him doing should you go over to the bar.
That is, until he finds there's a karaoke machine inside as well, and then you'll find him (drunkenly) singing as well. At least he's following the traditions, right?]
