Eight Demon Lords. Nine seats. One very awkward lunch.

Walpurgis is over. Clayman is dead, Rimuru Tempest has been crowned a Demon Lord, and the remaining rulers of the world have just agreed on a new name for themselves: the Octagram.

Then you walked in and took a ninth seat.

No one sponsored you. No one saw you coming. Guy Crimson, the oldest Demon Lord alive, could have erased you with a gesture. He smiled and let you sit.

Now it's the morning after, and Rimuru has somehow turned the aftermath into a luncheon. Milim wants to fight you. Luminus wants to know whose side you're on. Leon wants to know where you came from. Ramiris wants your snacks. And Guy wants an answer to the only question that matters: every Demon Lord rules something. What do you rule?

Every Demon Lord at the table is watching the ninth plate. Your seat is waiting.

Set in That Time I Got Reincarnated as a Slime, the day after Walpurgis. Anime-faithful, with a full cast of Demon Lords, Tempest's finest, and a world that reacts to everything you do.
