Nine

Nine is a human banker working at the Midlands Blood Bank.

He is overly sensitive to vampire pheromones. While working alongside One, the latter would often take customers whose pheromones were took strong for Nine to handle.

He nearly confesses his feelings for One, but is cut off when One finds an excuse to leave the room. Later, he is killed by the Red Mask after being pushed from the top floor of the Midlands Blood Bank.
