Well, this episode moves on to the 'sports' aspect of otaku culture, though it twists it with the sheer size of the 'conflict' between the dwarfs and elves. (poor goalies...) And of course, the innocuous high-five at the end illustrates the difference Shinichi tries to bring in, though Matoba is his usual tight-lipped self which continues to indicate possible agendas on the side of the government.
It's hard to tell if it's the Japanese government wanting to 'conquer' Eldant or more of a conservative "don't rock the boat" approach for stable relations, but there does seem to be inevitable conflict on the horizon between the two main governments, as well as Shinichi & Co.
But yeah, so far this show's been entertaining.
