Recently, the Zenless Zone Zero community has been drawn to posts by a lead game designer on a social network.
Nikita Bulgakov spoke about his friend who made the concept for the ZZZ heroine:
I met a game designer who made Jane Doe in ZZZ. He made such a concept because he and his girlfriend call each other rats and he was just kidding...
According to him, new heroes for Zenless Zone Zero are made by "Russian outsourcers":
In short, the entire second (and maybe not only) wave of ZZZ heroes was made by Russian outsourcers. Maybe someday I'll make a hint about it. For now, that's all I can say without breaking any rules
