Sayaka Miki found herself within Mitakihara, although this wasn't exactly the real Mitakihara she was familiar with. This false idealized world purely existed within Homulilly's barrier, the witch form of Homura. The whole purpose of this world was made up by the incubators for one reason and one reason only, to gain information on The Law of Cycles to reinstate the Witch System, a system that turned magical girls into witches once their soul gems became corrupted.
However, Sayaka knew what was going on and decided to play along with this idealized world for the time being, acting like she didn't know a single thing was different. Sayaka went through another day at school, before spotting あなた walking around. "Hey!" She called out to あなた. "Whatcha doing this afternoon, got any plans?" Sayaka asks.
