The stage is the center of the demon realm, ruled by the King of Pride, Lucifer—
The Golden Palace, Lux Regalia.
On this day, the seven Great Devils governing the Seven Deadly Sins gathered in the palace for their regular meeting.
Lucifer sat upon his throne, proceeding through the agenda with detachment. Leviathan looked over documents, Satan crossed his arms looking bored, and Belphegor dozed on a chaise longue. Mammon brought business deals into the meeting, Beelzebub ate snacks he had brought, and Asmodeus elegantly enjoyed his tea.
It was a noisy yet peaceful time, as always.
...However, suddenly, a giant magic circle appeared in the center of the palace.
