Fridge Logic: How in the world do Emaan keep their population up when their females become barren by the age of 18? Leads into Fridge Horror when you form suspicions as to how...
Actually pointed out in-universe; the social stigma placed upon women who choose not to bear children is extreme, to the point that adult women who refuse to bear children aren't even considered women - showing any kind of desire to one is so unheard of that Shaya actually strips in front of Kei and is confused by his embarrassment. It's actually quite surprising that Poputei's twins are only infants, implying that she squeaked in right under the wire just like Mimsy does with Kei.
Narm: The Emaan recognize Kei as a "tokuiten" soon after his arrival. The word can be translated as "singularity"; Imagin Asian used "Idiosyncratic Point". US Renditions, the original English-language licensee for Orguss used... "Differentiated Idioblast" — a translation choice that would live in infamy.
One for Orguss 02. The one line used to finally convince someone to get on a train to safety? Rendered in the dub as "GO BEFORE I THROW YOU DOWN ON THE GROUND AND RAPE YA!"
