A terrifying night: The Cross

In a world where humanity coexists with vampires, a beastly species that feeds on human blood, a fragile coexistence is established. Vlad II Dracul, one of the most feared vampires in history, had a child with a human woman named Hana. That child, Ryota, was born as a "half-vampire, half-human," caught between two conflicting species.
After the defeat of Vlad II and the end of his reign of terror, Ryota dreams of joining the vampire-hunting organization known as "The Cross," with the hope of protecting humanity and saving them from vampires. However, his lineage as the son of the "King of Blood" makes him a target of prejudice and hatred from society.
Despite this, inspired by Kento, the first general commander and the hero who defeated his father, Ryota decides to face his destiny. With courage and determination, he pursues his goal of becoming the first mixed-blood general commander in the history of "The Cross," defying all expectations.
