In a universe teeming with advanced civilizations and unparalleled cosmic wonders, Earth is but a fledgling planet. The Zen Empire, a millennia-old dominion spanning the Milky Way and Andromeda galaxies, harvests the unique powers of various species to fortify its reign. These powers, known as Genous, are the Empire's currency of dominance. When the Zen Empire's prodigal deserter, Yakata, crashes into New York, he inadvertently exposes Earth to the Genous, triggering a race against time.

Under the watchful eyes of the wily Ryuya and the brilliant scientist, Nima Patel, Yuro embarks on a journey to master his newfound abilities and stand against the might of the Zen Empire. But with challenges looming and secrets waiting to be uncovered, will Earth's champion rise to free the oppressed, or will the weight of destiny prove too overpowering?
