The OVA takes place in a nonspecific timeline in Darker Than Black. It’s basically a comedic side story about Hei and the police looking for a stolen item with a police agent who writes fan fiction unintentionally getting thrown into the mix. It’s a simple story to keep track off. Due to the fate of a certain character a fan of the series can immediately tell it takes place before the finale of season. The comedy is built around three things; love, some sort of association with the season of spring (allergies, mating seasons for cats), and character reactions to a situation. With knowledge buildup on the cast it makes the following events hilarious. However, it's all rather convenience how all the events are tied together within the special.
Bones Studio gives this OVA the same treatment they give the first season. Looking and sounding like an an episode in the main series. Background are drawn in detail and the animation is smooth. The voice acting from the Japanese cast and English dub cast are on par with the main series. Music remains the same with the second opening and closing songs in place. If you enjoyed the comedic episodes in Darker Than Black than this is a fun diversion.
Like stated in the opening paragraphs it doesn’t add anything or show what occurred after the finale. Let alone offer an explanation on events after the finale. It’s not essential to see this OVA, but if you it do it’ll be a good final reminder that Darker Than Black was also a fun series to see whenever it wasn’t serious.
