Hellsing: Volume 1 is the first volume in the Hellsing manga series. Originally it released in Japan on September of 1998 and then released in English on December 1, 2003.
Ten years ago, young Integra Hellsing ascended to the head of the Hellsing Organization after the death of her father Arthur. Her jealous uncle, Richard Hellsing, attempted to kill her, but awakened a dormant Alucard in the process, who proceeded to kill Richard's men. It is Integra who shoots and kills her uncle, thereby becoming the last descendant of the Hellsing bloodline. Alucard declared his allegiance to Integra and became her loyal servant. In present day England, Alucard is called to duty to eradicate a vampire and his ghouls. However, a female police officer named Seras Victoria is gravely injured in the process, and upon her saying she's a virgin, Alucard turns her into his vampire servant. Alucard then teaches her how to fight like a proper vampire by letting her take out Jessica after Alucard had already killed Leif. Later, on a mission to hunt down a vampire in the town of Badrick in Nothern Ireland, Alucard meets and fights Father Alexander Anderson for the first time.
