The universe has been subjugated under the harsh military rule of the despotic Ventika empire. However, a rebel police state known as G.P.P. has discovered the existence of a young girl named Muma, who may hold the key to toppling the Ventika empire once and for all.
Despite her terrifying potential, Muma suffers from amnesia and is imprisoned in a maximum-security facility. Tasked with breaking Muma out and safeguarding her, the G.P.P. dispatches one of their most elite operatives, Agent Kate.
After successfully completing her mission, Agent Kate is immediately given another assignment. This time, she must rescue a second individual who will prove crucial in overthrowing the empire. His name is Bavi Stock, a young man of extraordinary ability, but he too is currently incarcerated on the Ventika's specially constructed prison planet. Can Agent Kate free him? And what exactly is Bavi Stock capable of?
Bavi Stock is a two-part OAV series. The first film is titled "Bavi Stock 1: Endless Target," and the sequel is called "Bavi Stock 2: The Revenge of Iyzeman."
