Born into the prestigious and mysterious Hellsing family, Integra has been sheltered and educated all her life to take the place of her father as Bureau Director of the Hellsing Organization. Integra's Mother does not appear in her flashbacks, suggesting either that Integra never met the woman or that she died when Integra was very young. When she was 12 years old, Integra's father passed away and entrusted her with their family's mission to lead the Royal Protestant Knights and protect England against the vampires.
Immediately after Arthurโs death, Richard Hellsing, jealous of Integra for inheriting the family headship, attempted to hunt her down and kill her. Integra escaped her traitorous uncle and managed to reach a dungeon in the mansion's sub-levels, where her father had said she would find her salvation. Hoping to find a knight, she stumbled across an old, dried-out corpse instead. Richard found her, cornered her, and shot her in her shoulder, spilling her blood across the floor of the room. The corpse, who ended up being a vampire whom Arthur had imprisoned 20 years earlier, awoke and licked up Integra's blood. Rejuvenated, it proceeded to kill her persecutors, thus saving her. Richard desperately attempted to kill Integra one last time, but the vampire blocked his bullet. Picking up a gun, Integra shot and killed her uncle, becoming the last descendant of the Hellsing bloodline. The vampire, whose name was Alucard, became her loyal servant.
Not long after, Integra was knighted and introduced to Vice Admiral Sir Shelby M. Penwood, a former friend of her father. Upon seeing Integra for the first time, Sir Penwood said that she was far too young to fulfill her duty. He revised his opinion during the actual storyline, in which he admitted that it was an honor to have met and served with her in his farewell message, prior to his death. His sacrifice was just one of the many examples that helped solidify Integra's resolution about humanity's worth and continue her duty.
Integra as a child was more timid than she is now, yet a very willful girl, being brought up with a commanding presence that even Alucard respects. When Alucard became her servant, she grew more confident and comfortable with her position as head of the Hellsing family and a Knight of the Round Table. Much like Seras Victoria, Integra experiences a coming of age, gaining experience and losing her remaining innocence as events unfold and the war begins, transforming into a leader with an iron resolution who does not flinch at the first signs of danger and who gains wisdom through dire losses and betrayals. The Major recognizes her change from a "beautiful Frรคulein" (he goes so far as to apologize for calling her this) to the most dangerous enemy who stands in the way of his plans, calling her forth into his Zeppelin. Inside, she and Seras slaughter the remaining forces and then approached the Captain, Integra leaves Seras to go fight the Werewolf while she goes for the Major.
When Integra reaches the Major, she attempts to attack him but is stopped by a glass dome. There, she witnessess Alucard's dissapearance when he unknowingly drinks the blood of Schrรถdinger. After defeating the Captain, Seras arrives and uses her cannon to break the dome. In the process, she ends up blowing off half of the Major, revealing that he is a cyborg. Integra approaches the Major and guns him down, but a shot from the Major hits Integra in the eye. Integra and Seras escape from the giant Zeppelin.
After the thirty year transition, we discover that Integra is still the head of the Hellsing Organization but has accepted the fact that family-run agencies are a thing of the past and that government agencies will someday take over her organization. She and Seras have grown considerably close over the course of thirty years and the two anxiously await for the day when Alucard will return (though Integra has her doubts). In the final chapter, Alucard returns and attempts to bite her, but she shoots him before he has the opportunity. Once she realizes it was him, he explains his thirty year absence and says that he has not had blood in all that time. When Integra reminds him that she is an old woman now, he doesn't seem to mind. She bites her finger enough to draw blood and allows it to drip into his mouth after welcoming him back.
Family
Integra's known family includes Abraham Van Helsing, a Dutch metaphysican and philosopher and one of the main characters of Bram Stoker's Dracula, who was either her grandfather or her great-grandfather. Her father was Sir Arthur Hellsing, who died when she was 13 years old (12 years old in the manga), in 1989. Even though Integra had a far from normal childhood and did not go to school or a daycare, it was obvious that Arthur loved Integra very much, and wanted the best for her. It was from him that she inherited her current position as Bureau Director of the Hellsing Organization and her seat in the Convention of Twelve. Her uncle, Richard, sought to kill her and take the headship of the Hellsing family for himself. This was prevented by Alucard, when he blocked the bullet that was fired at Integra's face. Richard's exact motivations are unknown, though it is possible that he coveted the power and prestige of a seat in the Convention of Twelve. Another reason is hinted at in the OVA, in which her uncle continuously calls Integral "Frรคulein". This indicates a possible connection to Millennium. Integra herself fired the bullet that killed Richard.
There is a general assumption that Integra is not of full European descent. Her skin color is a creamy brown, darker than that of many other characters. In a flashback in the anime(Order 10: Master of Monster), there is a photograph of โan infant Integra being held by a woman wearing a sari, suggesting that her mother might have been Indian or of Indian descent.
Skills & Abilities
Integra is a superb fencer with fast reflexes and speed and is even able to block an attack from Alexander Anderson and behead a Nazi vampire after a car crash that shook her. Later, she met a head on attack by another vampirized Nazi soldier, cutting him down as he leaped at her.
Her aim with a pistol is almost superhumanly accurate. The anime displays her skill in Order 02: Club M, where she is seen shooting through the same hole on a practice target with what looks to be a Walther PPK (she also uses a Beretta 93R at one point). Another example of her prowess was her ability to shoot Jan Valentine six times with the same pistol, with the bullets forming a cross on his face (more impressive, considering the recoiled and was sent backwards from the force of each bullet), although this is demonstrated only in the original anime. However, she demonstrates similar abilities in the manga during Volume 6. Perhaps the best example of her shooting skills is in Volume 1 where she emptied a modified Sig-Sauer(Page 226) into Alexander Anderson's blessed bayonets, shattering them just as he was about to kill Seras Victoria despite the fact that the bayonets were moving.
Very intelligent, Integra was able to determine the route Leif and Jessica would take and who their next targets would be by following their patterns, and she devised a strategy accordingly. She was also the first to guess what Jan's mysterious clue, "Millennium", was actually referring to. In spite of her talents, she is still fairly young and inexperienced as a leader, and thus unable to grasp or deal with the full extent of the Major's plans. However, she makes up for that in her stern and unbendable will, not backing down no matter the situation. This clearly shown where she was able to order members of Iscariot, the organization that wants the Hellsing Organization destroyed, to follow her orders and protect her on her way back to her mansion.
It is also speculated that, just like her father and grandfather, Integra was educated in occultism and alchemy to be able to control Alucard's releases and to finish the process of building him into the "ultimate undead" (in the anime, this was made more obvious when Integra performed a ritual with Masonic imagery in Orders 11 and 12). However, there is virtually no evidence of such abilities on her part in the manga, and she seems to control Alucard through simple respect and force of will.
Integra seems to have a very strong presence and charisma, able to intimidate and scare Heinkel Wolfe by ignoring her intimidation with a gun and convinces her, (see episode 6 OVA) despite strong protest to light her cigar, the other Iscariot priests seem very scared by Integra's intimidation and will.
