Volume 9 covers chapters 69-79
Alucard sheds tears for his rival Anderson, a devout Christian warrior that became a monster of God to clean up the messes left behind by Millenium and fulfill his duty by facing off against the Lord of Vampires. He weeped for him because only a human can kill a true monster, he committed the same mistake that Dracula once did by sacrificing his humanity for unlimited power and mortality which ended up bringing him nothing but misery and ruin. Ever since Alucard was defeated by Van Helsing many years ago, he's been longing for the dream to die as a human, something that was robbed of him and then stolen from Anderson right in front of him. Though Anderson became a monster in the end, he was still a hero in his own twisted way, fighting to rid the world of ultimate evil and give the children of tomorrow a better future.
After Alucard and Anderson settle their score in the midst of the final battle for London, the Hellsing butler Walter betrays both sides he was working as a double agent for, swearing to face off against Alucard in a long awaited grudge match to end the suffering of the immortal monsters they have both become now that there is no longer any reasons to remain a faithful servant charged with hunting the supernatural.
The war is nearing its end. The nazi army has been toppled, the protestants and warriors of the church are no more. The undead vampire menace has been vanquished. All that remains is for the final adversaries left standing to settle their old grudges and take down the Major who orchestrated all of this madness to manufacture the greatest war between monsters that the world has ever seen.
