Comiket 84 saw the release of two more doujinshi from Kajishima-sensei — Tenchi Ban 13.08, which features War on Geminar, and Kamidake Onsen 11, which features Paradise War.
From Yahoo Auctions:
As has been pointed out, the cover of 13.08 is similar to the cover of Tenchi Ban 10.8.
And here are some bonus Paradise War images sent to me by AM.
H/T: Useless Tenchi
