Re:Zero kara Hajimeru Isekai Seikatsu - Memory Snow - Manner Movie

Subaru, Emilia, Rem, Ram, and their companions face a problem very different from monsters or magic: keeping a theater from becoming unbearable for everyone inside it. Phones, smoking, noisy behavior, and other distractions are transformed into playful examples of exactly how not to behave.

With the group delivering reminders in their own distinctive ways, simple rules become another source of comedy. The lesson is straightforward: silence the phone, respect the people around you, and let everyone enjoy the story without an avoidable disturbance.
