Hellsing: Volume 6 is the sixth volume in the Hellsing manga series. It was originally released in Japan on November 14, 2003 and released in English on March 1, 2005.
While Alucard remains trapped on the Eagle, Millennium starts attacking London. Zorin Blitz is told to head toward Hellsing HQ with a small group of soldiers, while the rest of the vampires attack London. They kill thousands of civilians and attempt to capture Integra. She manages to escape the vampire SS soldiers only after Walter tries to hold them off, ending up getting captured by The Captain. When the vampire soldiers manage to corner her, she is saved by a large group of pistol-wielding Iscariot priests, led by Alexander Anderson, Heinkel Wolfe and Yumiko Takagi. As Alucard uses his powers to steer the Eagle towards London, back at the Vatican Enrico Maxwell, the head of Section XIII Iscariot is given a major promotion, and with it he begins to mobilize the Vatican's fighters. Meanwhile, in the heart of London, while Integra is busy convincing the Iscariot members to escort her home, the Hellsing Mansion is under siege by Zorin Blitz and her forces. The only line of defense against this assault are Captain Bernadotte, his Wild Geese, and Seras. As the battle wages on, they must deal with not only the vampire Nazi forces strength, but Zorin's mysterious powers of illusion that almost destroys the Geese from within. The quick thinking of Seras frees them from Zorin's grip, but the battle is not over. After an attempted stolen kiss, the group splits up, Seras in one direction and the Geese in another, but not before promising each other they'll come out of this alive.
