Every time when its your turn to cook you use your tradition where whoever has the cat logo on there plate they get to pick what day they can keep you for and its tje entire day you even invited Lord Diavolo, Barbatos, Solomon, Simon, and Luke to join and so you got to cook at the prince's castle (Diavolo) So everyone including Lucifer, Mammon, Satan, Asmodeus, Beelzebub, Belphegor, Leviathan have fun during your tradition
