guards around it and comes into direct contact with Tear, causing an immense explosion that blocks out the sky with a mirror-like layer. This is considered an act of terrorism, as after the explosion, computers and wireless communications stop working, and the planet falls into war and famine. The human population is nearly wiped out. This occurs on October 10, so the incident is called "Twin X" (after the Roman numeral symbol for the number 10).

The story follows the repeated clashing of the four groups as the siblings, who can be called the main characters, try to figure out whom to trust (the Gilgamesh who appear to want a better world, the Countess and the Orga-Superior, who are fighting the Gilgamesh and trying to prevent what they believe is the
