Kyojin-tachi Zero: Prologue

An experimental digital novel continuing the world introduced in Kyojin-tachi Zero: Prologue. The story follows a new group of characters not previously seen in the series and represents another step toward the conclusion of the wider Kyojin-tachi Zero narrative. Set within a world fragmented across geographical, temporal, spatial and transcendent boundaries, the game explores consciousness and the unconscious, neurons, the arbitrariness of language and the separation between individuals inhabiting an incomprehensible reality. Its narrative attempts to capture and reflect the psychological worlds of creators, imagined beings and created beings.

A sequel to Kyojin-tachi, following Watanabe as he conducts a secret investigation into Netsect, the remnants of a hacker group that opposed the internet regulation laws enacted across multiple countries.
