Commander Lu Jin received the experimental subject Zero. The face is like his lover who died in battle, but the fighting instinct is like his lost opponent.
They are each other's perfect stand-ins for the dead. In their performances and trials, they touch upon the cruel truth hidden by the empire: they are created memory fusions and ordered to eliminate each other.
From using each other to relying on each other for life and death, they chose to defect. Among the stars, the commander and his weapons broke free from the shackles of the past, gave birth to true love from lies, and became the "Twin Star Ghosts" who fought side by side against the empire.
(This is a powerful interstellar story about double doubles, memory fusion, and the creation of real bonds on a false starting point.)
