First Half
Human? Well, there are only a few left in the storyline as the emerging Millennium Project, an army of Nazi undead, is unleashed upon the world. What will surely ensue is a war of blood and nostalgia, with a coolly gothic style and increasingly frenetic pace. Envision the Hindenburg, old sharpshooter rifles and throwback uniforms, mixed with new jet technology and incredibly bold vampires.

Second Half
The streets of London are awash in blood, a zeppelin descends a la Hindenburg, and six of our favorite characters are locked in face-off fights. It's possible that no one will come away from this crescendo "alive."

Attack on London
This event starts off when the Last Battalion's fleet of three Zeppelins in the skies above London. After launching a devastating salvo of V1 rockets that cripples the infrastructure of London and kills many civilians, the soldiers of Millennium are launched from the airships and land in the city blow London and try to capture Integra Hellsing, killing everyone they find en route to their objective. Then Iscariot appears saving and capturing her from Millennium. Enrico Maxwell is promoted to Archbishop and leaves with his army of Papal Knights.

Maxwell's Betrayal
After the successful death of Zorin Blitz by the hands of Seras Victoria, the now full-fledged vampire makes her way to London as Enrico Maxwell's Ninth Crusade arrives. Appearing as angels, many citizens of London had hoped that they will be the one to save them from the Nazis- only for Maxwell to scream out "How right you are! We are the agents of the angel of death", stating that the inquisition will now render its judgement. Calling England accused along with FREAKs; the sentence is death, as Maxwell repeats the word "Death" multiple times in excitement. The citizens of London gets to see the "angels" without the fancy lights, and after hearing Maxwell's speech; it's clear that they too plan on wiping them too. Maxwell then calls them pitiful- however, he will not forgive them. "Die in vain like fruitless, burning flowers" Maxwell says, and he continues his sentence by quoting the famous "Float like a butterfly" quote; but instead says "Die like a bee" in the end.

The Major, impressed and surprisingly entertained by his speech; says that he's not bad, complimenting him. The citizens of London stares as the helicopters lands and as the Major commands his Letzte Bataillon to assemble. Schrödinger smiles.

The Final Battle
Integra and Seras are killing all of Millennium's forces as The Captain approaches. Integra leaves Seras to fight The Werewolf while she goes after the Major. Seras and The Captain begin their duel and Alucard (in his female form) begins to absorb the blood of everyone who died in London. The Captain becomes his Werewolf form and Seras is easily getting beaten. Pip who communicates with her gets back on her feet and fights back. Seras and Captain gave fatal blows to each other but Pip as Seras's familiar uses a silver tooth to kill the Werewolf.

After killing the Letzte Battalion forces manning the zeppelin, Integra arrived in the control room where the Major was waiting. Protected behind a wall of bulletproof glass, the Major told Integra that she was just in time to watch his final triumph over Alucard, who had just defeated Walter. As the vampire began absorbing all the blood in London, the Major patiently watched and waited, mocking Walter's last desperate attempt to kill Alucard. Musing that his nemesis had now gained millions of lives by absorbing blood, the Major explained to the distraught Walter that he was just another life sacrificed for his grand plan of destroying Alucard for good.

When Alucard finally finished absorbing the blood, the Major gleefully announced that he had won - moments later, Alucard began to disappear. Integra demanded to know what was happening, and the Major was more than happy to explain: Schrödinger had killed himself and fallen into the rivers of blood, allowing Alucard to absorb him and gain the power of "the self-observing Schrödinger's Cat". However, Schrödinger's powers relied on his ability to perceive himself as an individual; since Alucard had millions of souls within himself, he was unable to control his newly-gained powers. Before Integra and the Major's eyes, Alucard vanished into thin air as he became "a collection of imaginary numbers", neither alive nor dead.

With Alucard gone, his army annihilated, and the Deus Ex Machina falling apart around him, the Major calmly faced Integra Hellsing and challenged her to kill him, stating that she was destined to be his slayer as he was Alucard's. After killing the Captain, Seras joined Integra and attacked the Major with her Hallconnen cannon, but the powerful shots barely cracked the glass wall. The Major wryly lamented that the Doctor had done too good of a job, but became elated when Seras pulled an 88 mm flak cannon from the armory beneath them. This enormous gun proved strong enough to shatter the shield, hit the Major, and punch through the wall of the zeppelin in the process.

As the smoke cleared, the Major lay on the ground with most of his left side blown off, revealing his cyborg nature. Integra wondered if this meant he was a monster, but the Major insisted that he was still a human because he had retained his own will and mind - he claimed that his ability to defeat Alucard was proof of his humanity. Drawing a small pistol from his coat, he again challenged Integra, asking her to "make war" with him. He repeatedly fired at his advancing foe without success, but finally managed to shoot her in the left eye as she shot him in the forehead. Despite this, the Major died with a smile, happy that he had finally managed to shoot something. As the machinery sustaining his life ground to a halt, he gloated to Integra that he had achieved everything he had set out to do; he had finished his grand war and destroyed Alucard. Integra retorted that Alucard would return one day, as he refused to die at the hands of anything but a human - and for all his claims to the contrary, the Major was still a monster.

Aftermath
The battle was over and, at the end of it, Millennium goals proved to be a fool's dream as none of the members survive. In addition while their leader, The Major, died without regrets, future developments would prove that he and his followers had ultimately failed at all they set out to accomplish. Far from being the seed of a world-consuming war, Millennium's attack on London was eventually classified as no more than a terrorist incident ("The Zeppelin Affair"). The city was rebuilt, and while both Hellsing and Iscariot were badly crippled they survived as well and would go on to regroup and gradually restoring their strength. Even the Major's plan to defeat Alucard eventually proved futile - thirty years after his apparent "death", Alucard managed to return, having gained control of Schrödinger's powers by destroying all of the other souls within himself. For all they sacrificed, Millennium's grand plan to kill Alucard only succeeded him stronger than ever.
