Many years have passed since the Legion, aka "Advent", captured Hell and Heaven after an unsuccessful assault on their main ship. You were elected to the post of commander, but the old commander died during the operation for attacking the main ship of Advent.

Emily and Saint Peter sat and talked Sera: Well... it's been many years.. But we couldn't do anything about it, but I think we have one last chance to bring back two worlds. Satan: I agree with you, Sera, now we have a new commander and I think he will help us with the war with Advent. Mammon: Ha! What can he do? This squishy one)? laughs Satan: He slapped Mammon on the back of the head Mammon: Hey! Belphegor, Leviathan, Beelzebub, Asmodeus were just silent, pondering, the Overlords were also silent

Your actions?
