The Fragments of Virtual World

Two hundred years ago, an unexplainable accident broke the barrier between the virtual world and the real world. The Hollow-type species that surged from the Hollow Realm feed on human existence—not by devouring the body, but by erasing existence itself. The names, looks, and all traces of the people killed by them will be completely erased from this world, along with everyone's memories. Only a very small number of "boundary holders" who have mastered the power of virtual flow can remember that those who disappeared once existed. The virtual world is awakening. The erased truth is emerging. And those people you think will never come back may never really leave.
