The Relationship between Alucard and Integra Hellsing

I've currently been re-watching the anime Hellsing. The plot of it revolves around the Hellsing Organization which is located in England and run by Integra Wingates Hellsing, who is either the great granddaughter or granddaughter of Abraham Van Hellsing. They purpose of the organization is to protect the country from vampires and the undead. She does this with the help of Alucard who is bound to the family through his capture 100 years prior. Through that bond, I would like to focus on the relationship and personalities of Alucard (who happens to be my favorite character in the series) and Integra, because I believe their hostel relationship is actually quite interesting.

The relationship and personalities between Alucard and Integra clash. For instance, Alucard's personality for being as old and powerful as he is, is psychotic and actually quite violent, he's also arrogant and cocky. All the while being sad and somewhat jealous of humans because they can die and he cannot, in the traditional sense. He also can't understand humans either. While Integra's personality is collected yet emotional with slight anger issues and she is a protectionist when it comes to her job. The relationship between the two no matter who you look at is strictly master (Integra) /servant (Alucard). Because when she was twelve years old, and her uncle tried to kill her after her father declared her as the leader of the organization, her blood restored Alucard, and from that moment on, he recognized her as his master.
