A while ago, I was lookup up info about Gunbuster VS Diebuster Aim for the Top! The Gattai, a compilation of Top O Nerae! and Top O Nerae 2!. Turns out the Japanese DVD release of the film came in two versions: one comes with a figurine set.
I didn't know how easy it would be to find said DVD set with figures, I only assumed the domestic release of the DVD wouldn't include them.
I'm glad I was wrong; Bandai Visual Planning 2 Gunbuster Gattai DVD Editions.
Hard work and guts!
