Don’t look now, there’s a new spinoff of Tenchi Muyo! coming, called Isekai no Seikishi Monogatari This time it’s based around his half-brother we somehow never knew he had.
I’m with the guy on ANN’s forums who said “I’d prefer him to apologize for the third one and do another one that ignores it completely. With my luck, though, it’d end up worse.”
Sigh.
