OVAs bundled with the 15-17th volumes of the Mushibugyou manga.

The film's story centers on Musashi Miyamoto, one of the most famous swordsmen in Japanese history. He pioneered the Hyouhou Niten Ichi-ryuu style of two-sword fighting and wrote The Book of Five Rings, a book that has been compared to Sun Tzu's The Art of War for its insight on tactics and strategy.

"A man with arms which can kill people like puppets is not aware that he himself has already become a puppet." In this short hand-drawn silent animation, a wandering samurai learns this lesson firsthand. Along his travels, the samurai comes across a straw dummy at the base of a tree, with a sword lodged in its body. Upon drawing it out, the samurai learns that the blade is imbued with magic, and immensely powerful. The power comes at a price, though, and wielding the blade begins to slowly drive the warrior mad. He now has a choice to make: remain himself, or sacrifice his sanity for ultimate power?
