Re-posting with a few minor edits. Part 2 arriving shortly.

As of chapter 140, the audience has finally gotten a look into the backstory of Shiguma the 6th, Issho, and their teacher, Kiroku, aka Shiguma the 5th. But still lingering are the questions of the what and why of the tension between Shiguma and Issho, why Kiroku passed down his art only to Shiguma, and the actual story within Shiguma's Art.
While we’ll likely learn more plot-wise about this conflict, I want to speculate on why Kiroku had Shiguma inherit his art / didn’t pass it along to Issho thru an emotional lens, and why Akane may succeed in bringing Shiguma’s Art to life again. It comes back to the heart of the question in the panel above: “Does a rakugoka have to be strong?”
( In the present day, Issho is a strong, stubborn man... )
