Tsumeai no Kurai is the 2nd set of Koryu kata practiced in Muso Jikiden Eishin ryu.
I came upon this accidentally on Youtube, it was not listed as Tsumeai no Kura, but simply as a demonstration at Nagoya Castle on May 5, 2010.
The way it is demonstrated here is somehow different from what I was taught, but it is the best video I have ever found about it.
