The Daily Record of a Certain Actor.

In a certain world, a daily record of an "actor" performing a certain play. At the request of Sazanka, a university student, Erika borrows her body to open the curtain on a "play." What exactly is this "play"? What lies behind the scenes of this "play"? Please enjoy the "play" woven by these two, shrouded in mystery. ※All stories here are fiction. They have no connection whatsoever to any real people, organizations, places, or anything else. ※Since this takes the form of a "daily record," there is no "ending." ※There is one element I have added based on the developments I'm currently considering.
