Artist's commentary
Hang in There, Kogasa-san 2143
Once you understand it, it's no big deal. They're dragging around the pillars, so it's just a chart that tells you "These logs will be passing by this point about this time." I started off like, "What the heck's 'Anayama'!?" so this is what happened.
Today is Hakurei Shrine Fall Reitaisai 3 at Tokyo Big Sight. My regards to everyone who'll be attending!
