Anthony Bryant, A.K.A. Tony, A.K.A. Baron Edward of Effingham of the S.C.A., A.K.A. Eddie Effie, is the closest to a real life Miroku that I've ever met. He's a friend of friends and I got to talk to him once years ago when he came to visit. It was interesting to put a face to all their stories. Heh. I swear the man has more appendages than Naraku but somehow it's not possible to get mad at him. I found myself wordlessly removing his hand while continuing our discussion without a break.
The man knows his stuff about Samurai culture though. He has published history books as well as a source book for gaming in the feudal Japan. At this site you will find useful essays on Heian society, arms and armor, clothing, and links to other useful sites. The illustrations can be very detailed.
The site hasn't been updated since 2004 and some pages were only partially done at that time. Some of the entries have a picture and some text but also something like "Place holding text" or "Blah, blah, blah" indicating that he planned to add more to it. I'm hoping that he does, it's good stuff.
