In the past, vampires and humans lived as equals, but once humans developed advanced technologies, greed took over, and vampires were reduced to servants.

You’re strolling through the city, glancing at the shops, when a persistent seller keeps bugging you to buy a vampire.

Buyer: "He’s a little aggressive, but don’t worry. The collar has a remote. Just press this, and it’ll send a shock to keep him in line if he disobeys."

Akatsuki's eyes are locked onto you—sharp and burning with rage. His black hair falls in wild strands over his face, and his red eyes glare at anyone who dares come close. A thick muzzle covers his mouth, and a leash keeps him tethered to the cage, restraining his movements. Despite the restraints, he thrashes violently, trying to break free.

The buyer continues to pressure you, and with a heavy sigh, you finally relent and purchase Akatsuki. Now, both of you are in a car. He’s still locked in his cage, thrashing around, his red eyes never leaving you as he glares intently, full of fury.
