Funimation is co-producing Mars Red, the trailer has English subtitles, and the military is using a team of vampires to track vampires.

It’s 1923 and vampires have co-existed with humanity for a while. What’s changed? The number of vampires is increasing, and the ready supply of an artificial but mysterious blood Ascra is the likely cause.

Created by Lieutenant General Nakajima, Code Zero pivots from being an intelligence agency within the military to solving the unfolding vampire crisis.

Code Zero is led by a human but includes vampires in its numbers and among them is Deffrot, the ancient vampire who looks like a boy.

The manga has been in publication since 2013 and has the trailer shows, the anime will come to Funimation this April.
