The sales weren't exactly bad, just moderate, about 1.5-2k sales per blu ray. In fact I think the company earned back what it was they spend on the series. On the othr hand the light novels quadrupled in sales around the time of the anime's airing. From 10,000 copies per volume to now 45-58k per volume.

So it was ok, and right now the part 2 series Last Embryo sold about over 30k on its first volume. Even so its still pretty good in the light novel sales. Though the years go by and a season 2 is becoming more and more unlikely. If Diomedea does make a season 2, its usually after 3 or 4 years since the first season airing, and the company RARELY does a second season unless the sales were good, like with Squid Girl.
