For example, when can the main five from Princess Principal appear in the Metacontinuity?

• Never, because the series didn't exist on the Metacontinuity's origin date, September 7, 2016
  
• July 9, 2017, because that's when the first episode first aired in Japan
  
• September 24, 2017, because that's when the final episode first aired in Japan
  
• February 11, 2021, because that's when the first movie was first screened in Japan
  
• not yet, because the final movie hasn't been produced and screened yet
  
• Other (fill in the blank): _____
