Rui Li spends her days at a screw factory in Satellite City No. 9, tightening bolts in an endless cycle that feels increasingly hollow. Something about her surroundings doesn't add up. The repetition, the sameness, the way reality bends just slightly at the edges where she isn't looking directly. When a figure called Anull appears with cryptic answers and impossible promises, Rui Li accepts a dangerous gift: the ability to transform. Armed with this power, she becomes Sirius, a thief operating in the shadows, stealing clues to the nature of her world and her own existence. What starts as a bid for escape spirals into something far larger. Each heist peels back another layer of deception, revealing that freedom from Satellite City No. 9 is just the beginning. The real conflict waits beyond, and Rui Li must decide how much of herself she's willing to risk to uncover the truth beneath everything she thought was real. A blend of heist thrills, mystery, and existential stakes wrapped in vibrant action sequences.
