The Azazel Cup was planned by Sirzechs Lucifer and Azazel in preparation of the sealing of 666 which would result in the lost of many mythology leaders. The Azazel Cup is created to serve as a proxy war among the myths and prevent hostility from brewing among myths which could lead into more wars.
Due to the inclusion of non-Devils, new rules are added to the Azazel Cup.
- Anyone can register as a King.
- A King can register anyone on his team as long as the targeted person isn't in another team.
- Devils with multiple Evil Pieces will be treated as 1 Piece for this tournament with the exception of Gods or God-level which will automatically be counted as 2 pieces or 8 Pawn pieces.
- Each teams starts with 1500 points and they would accumulate more points by playing matches.
According to Tiamat, if a team wins the tournament they can ask for anything and if the wish isn't super big then the rest of the team members can also ask for anything.
