hmm, I see volume 1. Methinks every volume is going to have it's own little group of people and the most important thing for the characters is to get through their volume alive. With Tokiko at the center of it all everytime.
My theory that the deaths are caused by negative emotions seem to be falling through though, I don't doubt there is still something supernatural at play but it seems to go deeper than initially thought.
That would be a plausible theory, but Voume 1's over and we still have three survivors, at least one of which is unlikely to remain that way (sorry Rina), and the investigation/sensational article isn't finished yet either.
So while we could see new "expendables" being added to the cast and introduced to the "end of chapter roster", I do think it'll be a continuous narrative rather than discrete volumes.
Idk, I'm still on board with negativity towards Tokiko being causal to the deaths, Rina not having died yet doesn't really go against that theory.
It's gonna be a great month if we keep getting a chapter a day :D
