It takes some real detective work to figure out the mystery that is Zenless Zone Zero, the upcoming action (roguelike?) game from Genshin Impact developer MiHoYo.
A Persona-style calendar icon showed up in the latest trailer for the game during Gamescom Opening Night Live. Different times of day seem to affect which characters will be hanging out in its urban environments. You can choose to chill with them and presumably earn their trust, but I have no clue what it has to do with the roguelike parts of the game. Maybe it'll unlock new attacks or outfits to wear.
