Hitoshi Okuda's Manga Was Its Own Continuity, Not an Extension
Fujimi Shobo's Comic Dragon Junior, 1994-2000 · "No Need for Tenchi!"
Hitoshi Okuda's manga, published in English as No Need for Tenchi!, ran in Fujimi Shobo's Comic Dragon Junior from December 16, 1994 to June 9, 2000, 12 volumes. It wasn't an expansion of the original OVA continuity, it was Okuda's own separate reinterpretation, known among fans as the "Okuda Universe," running in parallel to the original Kajishima-created OVA storyline rather than inside it. Early manga scanlators digitized imported tankōbon before official English volumes existed, hand-typesetting translated dialogue years ahead of Viz's commercial release.
