In the technologically advanced urban alliance, wealth determines everything. The super-rich reside in floating villa complexes, overlooking the slums and machine factories below. Identity chips are implanted in everyone's brains, linked to fingerprints, retina, and access levels—from the elite to the lowest servants, everything is controlled by this tiny chip. Servants, especially maids, are as lowly as dust. They can be beaten, killed, or even treated as "food" to satisfy their masters' bizarre fetishes. But for Arya Ross, all of this is merely an embellishment to her luxurious life.
