The Lunar Attack
Senki Zesshou Symphogear's Main Event.
This is the name given to the events that occurred when the Symphogear adaptors clashed against the spirit "Finè",
during her attempt to destroy the moon in order to stop the Curse of Balal from obstructing humanity's mutual understanding.
At the current moment, the crisis that threatened the Earth has been avoided,
but it's been acknowledged that this event has become the starting point for numerous paradigm shifts.
