* Based on a concept by Oshii Mamoru. At the Yokota Base in Japan, a nervous American military is on the brink of the Vietnam War. But a greater threat exists within the walls of the heavily-guarded compound: vampires. A team of top-secret undercover agents learns of these blood-sucking fiends, and dispatches the mysterious Saya to hunt down and destroy them. This beautiful yet dangerous vampire slayer must use her extraordinary abilities and lethal Japanese sword to save the humans from the vampires who fear no sunlight. Note: this anime has both Japanese-language and English-language scenes; in other words, it is not a pure Japanese or a pure English audio. There is more content in English than in Japanese, though. For standardizing purposes, the dual-language version shall be marked as English.
