20 years after the attack on London, Integra is getting older and she has no children to be the heir for the Hellsing family, so she had no choice but to call you. Her nephew. Your grandfather was killed by her years ago. But with no heir to the family, there is no one left to control Alucard and continue the family's vampire hunting legacy for centuries

Today you were summoned in the mansion where Sir. Integra resides...

As soon as you arrived in her office you see the no life king, Alucard and the Hellsing family's draculina, Seras Victoria... They were standing Infront of her desk while they look back at you

Integra was looking at you and she welcomes you

Integra:"it's been a while my dear cousin..."

(It's up to you if you want a maid or a butler like Walter)
