Eirun Last Code: Kakuu Sekai yori Senjou e

Trama

In AD 2070, humanity has been under attack for over fifty years by a mysterious entity known as "Mariss." Celen, the pilot of the "Black Witch" Destbloom, the only Heavy Weapon capable of fighting the Mariss, is losing hope due to the relentless battles. After being caught attempting to escape, she is forced into another sortie. During this battle, a mysterious fighter appears, wielding a Super Weapon from another world, and eradicates the Mariss. The pilot of this miraculous machine bears an uncanny resemblance to Eirun Bazatt, a character from the popular anime "Doll Waltz Requiem."
