Joe Shimamura and other cyborgs face a hidden threat: the Bresudo, a secretive group with extraordinary abilities and intelligence who have secretly shaped human history. Their motives are unclear, but they exert a powerful, unseen influence on the world. While most dismiss the Bresudo as myth, American journalist Lucie Davenport travels to Texas seeking a specific family connection and encounters the cyborgs. Having been relieved of their duty to protect humanity with the creation of the UN Guardian troops, the cyborgs now strive for peaceful lives.
