Mystery shapeshifter girl is alternately called Daisy or Himawarii depending on which one of us is speaking (Himawarii meaning sunflower, the flower that's repeated most often in game, and we're told she's named after Sensei's favorite flower).
There are three gods. Each of them has been given a C word to describe them (Callous, Calm, Concerned).
Nozomu was the Callous one, but he's dead. Sort of. HOPE seems to be taking his place.
Wire is the Calm one, and may also be dead, or at least dying.
Peredolia is the Concerned one, and introduced himself in one of the happy events in late chapter 2/early 3 (can't remember). He's been talking to us for a while -- whenever the narrator speaks only in lower case, that's Peredolia. I can't remember if his formal introduction was in late Chapter 2 or early Chapter 3, but it was in a happy scene from that period, and he's talked to us quite a bit since then. He's warned us an all-new season (Spring) is approaching.
