The current world and Sekkai are constantly connected by a portal called "Prism," and sometimes, matter and energy flows between the two worlds.

One day, monsters known as "Eights" come through Prisms that have opened up across the world and attack! Humanity rises up in opposition to face this unprecedented crisis using a strange power called "Skuld" which allows them to manifest the power of tomorrow, today.

The government gathers proficient Skuld users to send them into battle. Establishing the elite government soldier organization for annihilation called "Norn," the elite annihilation military operation is simply called "Eightraid."

After years of fierce fighting, the attacks from the Eights have left capital cities in ruin. In the middle of all of this, Norn finds a young boy who can wield an ancient weapon known as Ragnadragoon. His name is Asuma and they are successfully able to bring him into the army.

Considered humanity’s ace in the hole, can he properly protect the world from the Eights?
