Japanese Voice Actress
Sakakibara Yoshiko Integra's Japanese seiyuu (voice actress) is Sakakibara Yoshiko. She does an amazing job as Integra. Her voice perfectly suits Integra's anime temperment - mature and no nonsense; distant and cool, but also passionate and even scary when necessary; female, but not like the standard, high-pitched anime girls.

Other Anime Roles:

English Voice Actress
Integra's voice actress for the North American Hellsing dub is Victoria Harwood. Like many of the dub voice actors, Harwood is British, but I don't know anything else about her. She's very good as Integra and is, in my opinion, the most on-target voice in the dub. She sounds very mature, aloof, and collected. Her acting is excellent although she occassionally sounds flat, and she's sometimes not quite as passionate as she should be. For voice clips, click here.
