This one i traced this and did watch a lot of anime especially a few that were vampire-related like Vampire Hunter D from 1985 and the far superior Vampire Hunter D: Bloodlust. I think the artist did the video game artwork cover for the Final Fantasy series and did the manga for Vampire Hunter D. I think this series influenced Castlevania since It was made in the same decade, who knows maybe It's a coincidence. I do want to watch the Castlevania series on Netflix when I have the time. I heard It's a pretty well-done series.
