Cute little omake shorts that are, as usual, easily skippable, but are still a neat little time if you like the idea of telling some jokes with the characters from the main story. The bulk of these ones are fake science lectures with the characters playing straight-man and the fool together. I didn't think any were particularly clever until the "Shin" ones that released several years after the first two volumes of "Gunbuster" came out. In the very last one, there is a delightful shout-out to "Sailor Moon" that feels like a payoff for 90s anime culture generally as well as a running gag fromthese shorts. I dug it.
