The science lessons interrupt the chaos to teach you actual physics, then immediately go back to panic. Noriko and Kazumi explaining relativity while deformed and yelling is funnier than it has any right to be. This is what happens when a series loves its own premise so much it can't help but explain why the premise actually works.
The Coach returns with Noriko and Kazumi to break down more of the science hiding inside Gunbuster's universe. These two extra shorts maintain the same silly energy as their predecessors, shrinking our heroes down to super deformed proportions while they tackle concepts that actually matter to understanding how giant robots fight in space. The first focuses on additional principles the show introduced, while the final chapter wraps up the science lesson series entirely. Running just a couple minutes each, these episodes work best for viewers who already caught the original shorts and want more of this specific comedy angle. The humor leans entirely on the contrast between the show's actual scientific detail and the goofy, exaggerated way the characters present it. If you enjoyed watching the main cast stumble through explanations while the Coach barks corrections, these bonus features double down on that formula. Consider them extended credits sequences that reward series completionists with two more chances to laugh at how earnestly they explain relativistic time dilation.
