Darker the Black S2 OVA 4! the last one... Fills in Yin's capture. Excellent action and overall pretty awesome episode. These gaiden episodes were more entertaining than the Suou-centric season which was pretty good in itself. I liked seeing so much of the Hei x Yin interaction. The production and bgm were impressive as always.
Shiki 3! The new family of creeps introduce themselves around town...at night...cause they are obviously vampires..but nobody notices.
Denyuuden 4! Still progressing from the previous episode, Ryner is imprisoned for two years, and spends the time writing about his ideal country; a country where afternoon naps are possible. The end of the episode was very cute as Ryner is taken out of his cell thinking that he is going to be executed, but finding Sion has been made king. Lucile via Sion orders Ryner and Ferris to undertake a journey.
Hotaru no Hikari S2 3! is about goya which Hotaru loves and Buchou hates. Very, very entertaining.
