Simoun, Yuri Kuma Arashi Recommendations
Yuri anime with an emphasis on speculative sci-fi, social commentary, and serious weirdness. A surface layer of sexy character designs and suggestive scenes belies the thoughtful, introspective nature of both series. Common themes include violent conflict between societies, the political and social effects of organized religion, and a criticism of the idea that girls will have clandestine romantic feelings toward other girls but grow up to be heterosexual. Yuri Kuma is more aggressive on that last point; Simoun explores a broader range of themes.
Social commentary is explored in both shows, and both use the idea of lesbianism with sweet romances at their core. Simoun details their characters significantly more than YKA's short runtime allows, however.
