Someone was asking me if there's a list of all Tenchi works. I know some stuff is fairly easy (if time consuming) to piece together, but do we have an entire list that would include all of Kajishima-sensei's doujinshi and such?
There is a google sheet with the current list of scanlations concerning Tenchi GXP light novels, Kajishima Onsen doujin and such. It is pinned to the Ryo-Ohki thread top level. Here to save you the trouble: https://docs.google.com/spreadsheets/d/1PNm5pbUYgGDyu0N4xu28ErnaGIHHKsvssjxb05PjWpg/edit#gid=0
The other item to bring to your attention would be a comprehensive list of Kajishima side projects: please check with Jibril, their profile https://www.uselesstenchi.org/Forum/index.php?action=profile;u=6
