Bujinkan Budo Densho Libro 5: Shinden Fudo Ryu Dakentaijutsu de Carsten Kuhn
-Chi no Kata
-Shizen Shigoku no Kata
The books in this set are an excellent resource for Bujinkan training. The only problem that I sometimes have with them is that I believe they are written in German and then translated into English, which sometimes leaves some ambiguity in the descriptions. Highly recommend though!
I received the books I ordered in the expected condition. New and properly packaged.
