This is great but, I thought that Toei own the rights to AIC material and I'm not seeing that mentioned anywhere here?
I think Kajishima-sensei owns the copyrights to Tenchi stuff now. He gets credited as a copyright owner, and that was true for the True Tenchi Muyo! novels I adapted. I'm pretty sure that doesn't mean that AIC loses the rights over the stuff they produced. Subsequently, Toei owns 50% of that. However, if Kajishima-sensei outright owns the Tenchi Muyo! copyright, and he no longer has an agreement with AIC, then he can get any company he wants to produce his stuff. And considering how bad things were for AIC, I'm not surprised he went elsewhere.
Also, Kajishima-sensei may not have wanted to deal with Toei.
Hope the main Tenchi cast is going to be a decent part of it seeing as they're featured pretty prominently in the trailer. Sasami looks to be a teen again so I guess we know the time period it takes place in.
In anime terms, between OVA 4 and OVA 5 is what I'm hearing. All of the anime clips in the promotional video were taken from both of those series. That too suggests that Kajishima-sensei has copyright control over Tenchi in order to use AIC video.
While I'm still excited for this new GXP series, as I mentioned in a video on my other YouTube channel, expect a high entry bar, especially if the GXP series is set after the entire novel run.
