Found the conversation between Kaori and Tsuneyo that mentions sacrifices and the like. Granted, they're talking about chickens - but given how they're important to both Wires and Sekai/Pareidolia, and that the whole thing began because she ordered Tori Shio Ramen (which is what she orders as Sekai) this might have meaning:
Some other notes regarding this event (mostly about Kaori/Sekai):
There's just so much going on that I forget how interesting Kaori is. Like, is she something new to this cycle? It must be right? Just like Sekai is.
Also, unrelated, but I don't remember the theory being mentioned about each moon representing a different Sekai? Sometimes in the early to mid game Akira will say goodnight moon, or something like that - and I would imagine he's referencing Sekai. If anyone has already checked this it would save me the research.
