I have two Koinosuke cels. Really good ones up 
close too somewhat, and a Sai fabulous one. Taro 
or is it Taor? They hvae about 50 of them for 
pretty good prices and this one of Sai licking' 
Mr samerai? Hmmmmm...

I have not seen any art books, and the story 
comes from a magazine thing or something I read a 
while back-not even manga-or something...I could 
be wrong, but from my research in the series, 
never heard of those items. I know about other 
items and forgot the place...darn it...
