Hang in There, Kogasa-san 2151
I imagine there's all sorts of people there, since it's a festival, but somehow this just...yeah. (^^;) Some old guy was even ranting on the train back.
All sorts of stuff has happened for the onbashira before now, so safety is securely confirmed, and it seems they don't drop the logs if someone doesn't raise the white flag. And so, it took some time before they were able to confirm all was safe.
