Hellsing (2001)

While few actually realize it, demons and vampires have secretly prowled among humanity for ages. Fortunately, the Hellsing Foundation exists as a way to safeguard humanity against these dark threats. They're led by the daughter of the legendary monster hunter Abraham Van Helsing, but a new invasion of dark monsters has forced her to take more extreme measures than she otherwise would. She's recruited the help of a vampire named Alucard and his vampiric childe. They may be hard to trust, but they're also the last thing standing in the way of a sinister and relentless army of darkness.

Hellsing is an action show featuring Jouji Nakata and created by Umanosuke Iida.

Hellsing is currently streaming on Crunchyroll, Crunchyroll Amazon Channel, Funimation Now and Hulu.

It is also possible to buy Hellsing on Apple TV and Microsoft Store.
