Summary
the world of Zenless Zone Zero, where mysterious anomalies called Hollows began appearing and gradually destroyed human civilization. These Hollows distort reality and produce Ether, a powerful but dangerous energy that can corrupt living beings into Ethereals. New Eridu as the last remaining city on Earth was designed not to control Hollows but to coexist with them through strict systems, regulated exploration, and the use of Ether-based technology. Power in the city is divided between the Mayor and the TOPS Alliance, creating a fragile balance that keeps the city functioning.
Proxies—illegal but essential guides who help people navigate Hollows in real time. Among them is the mysterious and highly reliable Proxy known as Phaethon, secretly operated by Wise and Belle from their shop, Random Play. Hidden within their system is an unknown failsafe mechanism meant only to protect them, remaining dormant until the time approaches
