Tenchi Muyo! Ryoko's Setting Materials Collection, released in 1995 by AIC Club. It's in good condition for its age, with the obi (sash), but please understand that there is some deterioration due to the passage of time! Please forgive any oversights. This item seems to have not been handled by general bookstores, and it's a rare book that can't be found even when searching online. For those who were looking for it, how about this opportunity?
