Shogo Yahagi, a grey-eyed human male, begins his journey as a motorcycle-obsessed youth navigating a city mirroring 1980s Tokyo. His existence fractures upon discovering the Garland—a sentient, shape-shifting mecha motorcycle—revealing his reality as a simulation governed by the supercomputer Bahamut. Drawn into escalating clashes between militarized forces and the insurgent Dezalg faction, he retreats underground for months, evading authorities while aligning with the outlaw biker gang Trash. There, he reunites with Yui Takanaka, a fellow member, and battles adversaries using the Garland’s power.

His quest intertwines with a desperate pursuit to reconnect with Eve Tokimatsuri, a celebrity singer and TV host secretly linked to Bahamut. Bonds with Yui strengthen through shared trials, contrasting his yearning for Eve. A seismic twist unveils Shogo as Bishop Won Dai, the clandestine architect manipulating Bahamut, forcing him to confront dual identities and the ethics of control.

Driven by rebellion and a hunger for truth, Shogo’s evolution weaves resistance against oppression, fractured loyalties, and the paradox of wielding power within a fabricated world. His narrative arcs through defiance, self-discovery, and the volatile intersection of freedom and destiny.
