About: Zen is the result of a Yonaguni experiment. They created synthetic clones of themselves to merge their souls with, so they could live and fuck forever. But the unexpected happened. The synthetics became self-aware and developed their own desires and a burning lust that even the Yonaguni were unable to satisfy. After their extinction, Zen and his kind were left behind, forever unsatisfied. Will you be able to give this hot body what it needs?
Both Zen and Nier has light colored hair but unlike the former who has black tips, the latter is blue. While black is predominantly in his outfit, the white colors have been turned blue. Like Nier, both are artificial beings, Neir being a Replicant while Zen is a synthetic human who then gained consciousness. Unlike NieR who's travelling around to find a cure for his sister, Zen is instead looking for a partner.
