This is the Ninjutsu Black Belt home study course by Richard van Donk.

There are other copies of this course floating around but to my knowledge, this is the first time the complete
package has been offered:

1. All videos from 9th Kyu to 1st Dan, ripped from DVD. Note that these were originally 1980s video productions, so don't expect blu-ray quality. However, I think they're a little cleaner than the VHS rips in circulation.

2. The "Learning Japanese Phrases" audio CD.

3. The complete 270-page Shodan manual, scanned into PDF.

Enjoy!
