Ability Summary
Intro
It has been 16 years since the Gates appeared in this world. It hasn't even been that long. How did the world end up like this...
Before the Gates appeared, people lived peacefully, repeating the cycle of commuting, working, resting, and eating. Until the day before—
That day. That was the day the Gate opened for the first time. Monsters began to emerge from that blue portal... that rift in space.
Giant insects, mangled hybrids, living plants, humanoid things... and then, a few months later.
People capable of defeating those monsters began to emerge in this world.
