Lucas Alhamera, a scientist, attempted to terraform a planet resembling Earth called Antroseda but continuously failed.Overwhelmed by despair and the crushing weight of loneliness, Lucas attempted to end his own life using a euthanasia capsule. However, just before his life could be taken, he was abruptly awakened by a notification.[As the last of the dominant species, you have been chosen as the new Overseer of this universe.][The cycle of life must continue to preserve balance.][Select planet as the birthplace of the new species (default)][Select another planet...]With the Overseer System he had obtained, Lucas began what he had failed to do for hundreds of years: reviving a dead planet and creating a new race to succeed humanity.

Heaven and Earth serve as the guesthouse for all living things, with Time being the sojourner since time immemorial.

As with the difference between dreaming and awakening, the distinction between life and death is diverse and confused, and changing.

What awaits us beyond time, once we have transcended life and death, heaven and earth?

You shall become king—

Ruling over all “serpents” in the world…

Become the man who bears the brunt of dragonkind’s fear and hatred.

A modern era when humanity is threatened by attacks from giant dragons flying from beyond the sky.

Controlling “leviathans”—serpentine spiritual beings created through magic—humanity is locked in a protracted war of resistance against the dragons.

Fortunately, there exist witches known as “magi”—battle maidens of salvation who formed covenants with “serpents” in order to combat dragons.

Nicknamed Hal, the young man called Haruga Haruomi makes his living through facilitating the covenants of these girls.

At the (partially coercive) request of his childhood friend Asya, one of Europe’s top witches, Hal returns to Tokyo New Town after an absence of three years.

Accompanied by the beautiful Asya whose appearance rivaled a fairy’s, Hal is running all over the place to secure his base of operations and taking care of matters related to school transfer when the elite dragon Soth suddenly attacks—!?

Life has been breathed into a brand new myth between dragons and dragonslayers.

A grand opening to the “birth” of a top-class battle epic!
