Hellsing

Integra Hellsing leads a Hellsing unit to Cheddar after reports of disappearances linked to a mysterious priest prompt investigation. A D11 team is sent, but several agents are killed, leading to the deployment of Alucard. During the conflict, Seras Victoria, a D11 operative, battles her former colleagues turned ghouls, and after she is wounded, Alucard saves her life by turning her into a vampire.

Seras begins a challenging new chapter as a member of the Hellsing Organization after being declared "lost" during the Cheddar incident. Struggling to adapt, she faces limited patience from others despite some initial tolerance. Her opportunity to prove herself arises with the emergence of new threats in the form of Rafe and Jessica.

A surge in vampire activity prompts concern, especially after an Italian student is discovered with a computer chip that has transformed him into an artificial vampire. Despite the chip's removal, he rises again, driven to find his lover and kill those who interfered. Hellsing becomes involved to stop the threat, but others also have interest in the boy.

The Hellsing Organization investigates disturbing snuff films circulating online, including one showing one of their own being killed. At the same time, Seras participates in an operation led by a harsh former SAS officer to clear an apartment infested with ghouls. The mission risks exposing the organization's existence when a mole leaks live footage of the raid to television.

Seras continues to struggle with her transformation into a vampire, though she is gradually adjusting to her new identity. Meanwhile, the Hellsing organization faces a serious threat when the deranged Valentine Brothers launch an attack by infiltrating their headquarters with a large force of Ghouls.

The Valentine Brothers, Luke and Jan, launch an attack on the Hellsing organization's headquarters, unleashing a horde of ghouls that kill and devour many humans. Victoria and Walter retaliate by wiping out hundreds of ghouls using deadly threads and heavy weaponry. As Arucard confronts Luke, he is devoured by a monstrous dog summoned by Arucard, while Jan chooses to commit suicide rather than reveal the mastermind behind the attack to Sir Integra Hellsing.

Following a massacre that claimed more than half of the Royal Order of Religious Knights, Sir Integra Hellsing, Arucard, and Seras investigate the Valentine Brothers and their connections, leading them to suspect the Vatican's Iscariot Organization. Arucard is drawn into a confrontation with the powerful exorcist Alexander Anderson.

Victoria investigates the origins of the "freak chips," a mysterious substance that transforms humans into ghouls, seeking to uncover who is behind their creation.

Alucard faces a formidable new adversary, the ancient vampire Incognito, who proves to be a powerful threat. The situation escalates when Sir Integra's life is placed in danger, forcing Alucard into a desperate battle.

Integra undergoes a life-saving operation after a near-fatal incident, during which flashbacks reveal her rise to power within the Hellsing Organization. Her uncle, seeking control, attempted to assassinate her while Walter was away, but Integra survived by retreating to a hidden prison cell where she encountered Alucard. After being wounded and using her blood to awaken him, Alucard defeats her uncle's men and acknowledges her as the rightful successor. The episode ends with Integra recovering successfully, greeted by Walter with afternoon tea.

As the threat from the freaks escalates, the Royal Knights convene a meeting with Integra at Westminster, with the Queen's involvement planned for a ceremonial event. To mislead the public, the meeting is announced as taking place at the Tower of London, while Integra's actual ritual occurs at Hellsing Castle. Meanwhile, Fargason and his men await the freaks at the Tower, only to be ambushed by Incognito and his forces, while Alucard abandons protocol to engage in battle.

A violent conflict erupts at the Tower of London, forcing Integra to cancel a meeting with the Queen. The Hellsing forces engage S.A.S. ghouls at a decoy location while the organization is falsely accused of terrorism by an unknown media source, prompting the British military to intervene. As Fargason sacrifices himself to mislead the public, Seras Victoria arrives at the tower just in time to witness his death before joining the battle, while Alucard heads toward a final confrontation with Incognito.

The episode features a intense battle between Incognito and Lord Alucard, during which Incognito seemingly defeats Alucard using bullets imbued with the power of the human God. Earlier in the fight, Ceras Victoria is injured and learns she must drink blood to recover, experiencing it for the first time through her fallen master's blood. Offended by her inexperience, Incognito departs to summon a demon from Hell.
