10. "RE: Chapter 2: Ostflamme"
In response to message #9
My personal bet for Ame would be showing up to investigate the shenanigans, either as an Official Presence from Allied HQ, or just on her own.
Though with both Sakuya and Ame both having time-manipulating pocket watches and both being in the same area at the same time, I can only imagine that Kronii is absolutely dyspeptic.
