This is the weirdest portrayal of Miyamoto Musashi you didn't ask for.

There's not much to be said about this manga, you will follow 4 short stories (the title means 4x4, meaning 16 guardian deities of Buddhism) revolving around Musashi's dealing with tragedies of different women who reminds him of his trauma of losing his older sister, with who he had some level of an incestuous relationship (yes you read that right, Miyamoto Musashi the warrior with onee-san fetish complex).

If you are not for the art, which is a decent Gekiga art, this manga may be a huge letdown. And yet on this matter, it is not all that amazing because the author uses a lot of repeated panels with the exact same facial expressions.
