Unfortunately; this is one of those fabled "Good Shows That Are Too Short / Ended Too Abruptly." It was based on an h-manga; and it featured too much material for the h-anime to run this short. So yeah. It follows the same formula as Ikkitousen and Koihime Musou; being based on China's Romance of the Three Kingdoms. Only, WITH SEX. "So we can make enough children to create an empire!" So says the Ryuubi Gentoku of this series. Takaaki, who's name looks like "Shokatsu Koumei," gets forced into becoming a "member" of Ryuubi's group. I'd make a better recommendation for this h-anime if it didn't cut itselfoff at episode two.
