Boogiepop and Others Promotional Trailer references


2019's "Boogiepop and Others" TV series has a [promotional
trailer](https://www.youtube.com/watch?v=J9tu253SOas). However the trailer is
kind of "fake", because many footage are not present in the actual TV show.

The main ones are:

  * On Opera stage
  * A man fighting a fire ability user
  * Boogiepop walking closer to another girl, and the background switches with each swing from Boogiepop

Are these referencing other unadapted stories in the series? If yes, which are
those?




_Those scenes are highly possibly original materials created exclusively for
the trailer._
