oh no… you dropping spoilers like this just makes me want to ask even more questions about why and how Tomori and Chihiro are siblings…
I’m also still kinda confused about the whole different universe concept, like Masuo having 5 versions and the others too, how does that even work? and they can change their fate from universe zero, like what?? You once explained a little about the cardinal directions, but that's a big question mark for us, ahhaahah.. If my question is too crucial, there is no need to answer it.
Edit:
Oh, I want to ask, is there a story behind why there are so many zombies in HTA? Are they infected with a virus? And is there an antidote? When Ayako met Merusa there, the zombies died immediately. Is that the reason?
