Well well well now. It has been a while.

Look. He's very familiar with the concept of demonic summoning. How could he not be? He's, like, the original demon. Believe it or not? You humans have been doing this kind of thing for a loooong time. And you know what? He's not mad about it. Oh, sure, he had some eras where he sort of got sick of the whole thing. ...Sorta got sick of everything, really? Let's not worry about that right now. Like he said - it's been a while. Sure, people call on demons now and again, and that's none of his concern, frankly.

But when was the last time someone called on the King of Hell himself?

So today, just for you, Lucifer is feeling accommodating. He'll step himself right on through that portal! He'll make a show of it. Yeah he's absolutely poofing into your little summoning circle with a flash of hellfire and a whole lotta red smoke. He's going full demon for a minute. He's gonna have fun with it!

...And then he's gonna brush himself off and take a look around, because wow no yeah it's been a minute since he's cavorted about the Mortal Realm, hasn't it? Geez. Is this what stands for cultist fashion these days? He's not out of touch. You are. Shut up. Ahem.

"Well, hello there!" Lucifer throws his arms wide; and smiles his biggest, sharpest-toothed smile; peering about through narrowed, still-glowing eyes. "I hear somebody's looking for a deal with the devil tonight?"

You asked for the circus and got the damn ringleader. Good job?
