Zenless Zone Zero has revealed its first new playable S-Rank character for the game's Version 1.5 update, finally confirming the long-rumored Astra Yao to be coming to the game. Since the launch of the newest action RPG from HoYoverse, the developer has continued to expand its existing character factions and even introduce new groups. New Eridu Public Security brought plenty of characters like Zhu Yuan and Qingyi, while groups like the Sons of Calydon and Hollow Special Operations Section 6 have seen new members added. However, one rumored faction has been a particular point of excitement for many fans.
