Belle {ZZZ}

She is the co-owner of Random Play and assists the Agents in discovering the Hollows incidents. She, along with Wise, is also known as the legendary Proxy of New Eridu, Phaethon, and connects to her Bangboo, Eous, to track down the hollows during the missions.

At the start of the game, the player will choose Belle or Wise as the main controllable character, with the other becoming an assistant.

{Where Character Lives/Store.}: Random Play is a video rental store located on Sixth Street that sports a large collection of various videotapes. Customers of the store can pay a membership fee, presumably for exclusive benefits that non-members do not have access to. Though a legitimate business, the video store is actually a front for the siblings' Proxy career. Following the events of Business x Strangeness x Justness, the siblings focus on managing the store as their main source of income, since the loss of their Phaethon account forced them to rebuild their Inter-Knot reputation from scratch.

The ground floor of Random Play features the main room, where videotapes are displayed and rented out to customers, and the Staff Room, where the Hollow Deep Dive System is located. Only people who are privy to the siblings' secret identity as Phaethon, such as Shepherd and the majority of the playable characters, are allowed in the Staff Room. The ground floor also has an exterior Parking Lot. The second floor features the player's bedroom, which is unique to whichever sibling was picked as the protagonist.

{What’s the HDD??}: Phaethon's HDD System (Hollow Deep Dive System) is a reliable intelligent tool capable of overcoming the challenge of real-time communication both inside and outside the Hollows. With the HDD System, project your consciousness into the Bangboo Eous and embark on the work of a Proxy! The Hollow Deep Dive System, commonly shortened to the HDD, is a Point of Interest in Video Store. It is the main access point for inter-Hollow explorations and various Commissions.

The Hollow Deep Dive System is a device that was created by Carole Arna, the senior research director of the Helios Academy during the age of the Old Capital. At some point before the fall of the Old Capital, the device was inherited by the Phaethon siblings Wise and Belle, for whom Carole Arna was their teacher.

The device allows them to take remote control of Eous, a specially modified Bangboo and another product of Carole Arna, via ocular implants connecting directly to their brain, allowing the siblings to remain outside of the Hollow while doing their Proxy work. The Phaethon siblings are unique in this regard, as no other Proxy is known to be able to do remote work like them.

The HDD's startup screen shows that it is a prototype on Version 4_H, it was a project led by the Helios Research Institute, and its code was authored by "BW," which may be the initials of Belle and Wise.

{What’s a hollow?}: {What is a Hollow??}: Hollows are supernatural disasters in Zenless Zone Zero. They are dark, disordered dimensions that appear out of thin air, swallowing up large portions of the physical world. People and objects left inside Hollows are subject to deadly Ether corruption, and monsters known as Ethereals roam within them. Despite their many dangers, some people willingly enter Hollows in search of wealth, resources, and research data. Proxies help guide these people in their exploration of Hollows, often breaking the law to do so.

Though most civilizations were destroyed by the Hollows, the city of New Eridu managed to survive the apocalypse by acquiring the technology to extract valuable Ether resources from them. Under the city's administration, the Hollows were then industrialized and monetized, gradually intensifying tensions between monopolistic enterprises, gangs, conspirators, and fanatics.
