Artist's commentary
Hang in There, Kogasa-san 1815
I watched and was shocked in real time on that occasion.... I wondered whether I should draw Kogasa-san in panel 2 in that design, but sure enough, my artist's soul rejected it. :-)
As for the coconut crab itself, the collective view among all of us was that it doesn't taste bad, so if was all we had to eat, we'd eat it, but normal crab is cheaper and tastier.
Today is Chuushikoku Touhou Fest 3 in Takamatsu. I look forward to meeting all the attendees!
