On May 6th, Gainax held their second Talk Live Animated Event. Basically what happened was they showed the Yoko music video in full, showed the new mecha designs from Lagann-hen, discussed animation stuff and anecdotes from when they were working on Lagann-hen, and showed fan videos submitted for the event as part of "Gurrepala: Origin" (one of which can be watched here).
Guests were given different badges (with the staff all wearing badges of Anti-Spiral drinking beer) and the Rakugaki Core Drill 2.75. New posters drawn by the animators were also on the walls. DOWNLOAD THEM HERE.
So far the Rakugaki Core Drill 2.75 hasn't been scanned in full yet (that I've seen), and folks on 2ch are citing the notice banning unauthorized copying as the reason, but since that hasn't stopped them from scanning this stuff before, I suspect that this time it has more to do with the sheer volume of the book (40 pages).
Some pages have surfaced though, and I'll put those under a cut along with some more details since they have spoilers for Lagann-hen.
And various 2ch threads.
-Kamina appears in Yoko's music video, which made Kamina/Yoko fans happy and teary-eyed. They had a video letter of Marina Inoue giving her thoughts on the video and calling Nishigori Yoko's father.
-They said that if the Yoko box sells well, they will make one for Nia too.
-Yoko W Tank has three forms: Space Yoko W Tank, Tengen Toppa Yoko W Tank, and Tengen Toppa Yoko SP. Yoko SP is just 14-year-old Yoko in mecha form, and the "SP" stands for "suppadaka" (stark naked). Nakashima improvised the name in 5 seconds. Also, the boob missiles were Imaishi's idea.
-Super TTGL and Super Anti-Spiral have no designs; they were all drawn by Yoshinari himself.
-Apparently Yoshinari has been surprisingly energetic recently (he's usually a very shy, quiet guy).
Specific scenes animators were in charge of-
Kenichi Yoshida: Solvernia
You Yoshinari: Giga Drill sequence
Sushio: Simon VS Anti-Spiral fist fight
Rakugaki Core Drill 2.75:
Front cover, drawn by Nishigori.
Back cover by Yoshinari, featuring Tengen Toppa Solvernia and Tengen Toppa Yoko SP.
Fist fight by Sushio.
Akemi Hayashi thinks beat-up Simon in prison is sexy and wishes she could have gotten to draw that part.
Tengen Toppa Enki Durga/Tengen Toppa Gurren Lagann OTP...?
Another Tengen Toppa Gunmen, not sure which.
Hopefully the rest will be scanned eventually. D:
