Hellsing manga series from writer and illustrator Hirano.

English-language issues and special compilations from the series were subsequently picked up by Dark Horse.

Hellsing follows a reimagined version of the
Dracula mythos that adds an extra “L” to the esteemed doctor’s name, while placing female protagonist Integra Hellsing the great-granddaughter of Abraham Van Hellsing at the center of the action.
