Ragnarok

Twilight of the Archdemons

What Happens
Long story short/not written - Archdemon Lucifer finally achieves his Ragnarök;Lucifer mode and begins destroying the Gigaverse. Archdemon Mammon is woken up to stop this...

...

Mammon, Giga Angel Artus, and Archdemon Asmodeus combine their newly strengthened powers to stop Lucifer before he can fully destroy the Gigaverse... (They mostly fail I think) ...

Archdemon Lucifer has left behind Avatars of himself to take care of any messes if need be. It usually results in a huge battle.

...

It all culminates in a duel to the death between Ragnarök;Lucifer and a newly formed Ragnarök;Mammon, known as The Final Battle.
