>why are /zzz/ devs so invested on NPCs?
Because they went the extra mile to design cool NPCs and players get attached to them (Venus is an outlier in that she became kinda popular despite having a generic design)
>will we ever get to see Venus or Orchidea again?
Definitely. But since Venus 2.0 didn't get that much attention and Sweety is absolutely dominated the game's art trends and tags, I don't expect to see Venus again for a while, and probably not in as big a role as being the closing act of an event.
