Kuromitsu was born very long ago in the country of Wakasa. Three years after the death of her father, she found the body of a vampire washed ashore, whom asked her to drink her blood in order to survive. Panicking, she ran back to the village, telling two men she encountered about a living "corpse" that desired her blood. When she and the men went back to the body of the vampire, however, it acted like it was dead.[1]
Tempted by her beauty, the two men then tried to rape Kuromitsu, but were stopped by the vampire, whom effortlessly grabbed one of them by the throat and threw him into the sea, causing both of them to flee. The vampire then bowed down in order to suck the terrified Kuromitsu's blood, who calmed down after he had digested his "meal". Kuromitsu gained the feeling she and the vampire were blood relatives, and after sucking his blood aswell, she left Wakasa.[2]
