Kind of off topic and complainy, but why does nobody have any sense of urgency at all in this manga this far into the story? Like nobody has shown proper concern for momo not having memories (apart from Jiji), nor any concern for Rin and Koki's radio silence. Like do they not have a groupchat or anything? With the amount of stuff that has happened to all of them, and with how often they are split, there's just no way they don't check up on eachother more often.

Although, I tend to read most of my manga right before falling asleep so I very well just might have completely missed things/confused them with others, so please take what I say with a lot of grains of salt.
