I’ve seen my fair share of ecchi shows. I haven’t seen many ecchi action shows, though. Most of the ones I’ve seen have been set in high school or been otherwise harem- or romcom-centric, like Oniichan dakedo Ai Sae Areba Kankeinai yo ne! and Oniichan no Koto Nanka Zenzen Suki Janain Dakara ne!!(A pattern? What pattern?!). This is kind of surprising when I think about it, because there are a bunch of ecchi action shows out there, like Seikon no Qwaser and Maken-ki. But the only one I’ve seen is Hyakka Ryouran: Samurai Girls, which I wasn’t very fond of. I didn’t even bother watching the second season. The reason I haven’t been interested in these shows is that it seems that they all basically use the same formula: The girls, many of whom are very… well-endowed, either get their powers by taking off their clothes or their clothes fly off when they use their powers, and that’s basically all that the shows have in terms of writing.
