In the year 2139, the world changed. Fundamentally and irrevocably.

Everything happened too quickly. The sky cracked like an egg and armored dinosaur-like monsters lurched out of the fissure. The split, though small at first, quickly widened. Within a few short hours, these beasts had overrun the world.

Countries, even those who had been enemies for centuries, sounded a global alarm. Political differences were cast aside as humans scrambled to find a solution—any solution—to what became known as the Great Disaster 1.0.

Human experimentations began, first in reluctance, then in earnest. As days turned into weeks and weeks into months, failure rates remained high. Desperate for results, global authorities started turning a blind eye to how experimental subjects were sourced.

Countless victims were kidnapped and trafficked to state-run laboratories. Shi Tian was but one of them. But unlike those who died nameless, in pain, and unrecognizable, he had the fortune of surviving after being injected with humanity’s last hope—an integrated chip.

Except… the chip remained dormant. It seemed that certain circumstances must be met before the chip could be activated. What those circumstances were, even the scientists in charge could not answer.

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.
