Okay, I'm gonna try my best to explain this Manga that I read but I can't find it anywhere after the website deleted my lists, but it was about this girl who experienced this earthquake when she was visiting her uncle or something and then they continuously traveled through different time dimensions, and they encounter these group of kids who also been going through the same time loop that's all I can remember. I think they were also running away from this black substance but I could be be wrong

Does anyone have any tragedy/horror recs???
