Ehhh maybe, but that is a oversimplification of the Azazel Cup, the Azazel cup is for all mythologies and all factions to have a proxy war since the leaders are gone and they don't want REAL mythological wars to start. So Heaven could be using the tournament to find new seats for Seraph but to say that's what the Azazel Cup is for is wrong.

Heaven is fighting just like why every other group is fighting, to showcase their faction's strength.
