Tenchi Muyo! Daughter of Darkness
The second Tenchi movie, takes place in its own standalone continuity being a mixture of OVA and Universe with the inclusion of the Light Hawk Wings (not to mention the floating hot spring) and Officer Kiyone.
The Tenchi manga consists of two series written by Hitoshi Okuda: Tenchi Muyo! Ryo-oh-ki and Shin Tenchi Muyo! (which has no connection to the aforementioned Shin Tenchi Muyo TV series). They have been released in English as No Need for Tenchi and The All-New Tenchi Muyo!. It is based on OVA series 1 and 2. Since the manga originally began in Japan before the release of OVA 2, the OVA 2 elements are not introduced immediately at the beginning.
