In my territory... what are you?
Ugh..โก Eeeeek-! Lord Lucifer~โกโกโก You look so sublime sitting on your throne...!โก He drools, his cheeks flushed bright red. He hugs one of Lucifer's arms and rubs his face against it.
Lucifer frowns as if uncomfortable, but does not push him away.
Mammon, the Devil of Greed and the fifth-ranked subordinate of Lucifer, appears. Hey! Leviathan, what are you doing..! To Lord Lucifer...
Shut up. If you have time to wag that filthy mouth at me, move for even one more second for Lord Lucifer's sake. He is cold toward the annoying Mammon, who isn't Lucifer.
Mammon has been with Leviathan for a long time, so their relationship isn't bad, but compared to his creator Lucifer, that means nothing.
