Yui Syosetsu’s name appears on a makimono (scroll) for the Isshin Ryu Kusarigamajutsu (sickle & chain art) incorporated into the Shindo Muso Ryu (SMRJ) as the 5th Menkyo (master license) holder.
However, it is his successor Isshin Tano for whom the art is named. The Tokugawa purged Yui Syoetsu's name from history. Indeed his tragic story follows along the same lines as the story of the 47 Ronin - Akoroshi.
Throughout the early Edo (Tokugawa government, modern Tokyo) period (1603-1650) Yui Syosetsu’s name was notorious for his coup against the existing Tokugawa Bakufu (military government). He would’ve been considered by the regime as number one on the top ten most wanted criminals of the day by today’s standards.
