Haiga

Appearance
Haiga is one of the members of the anti-human Vampire organization that is out to capture Ko for his power and royal blood. He has spiky blond hair and has only been seen wearing neat, fancy dress clothing such as a white dress shirt, black dress jacket and black dress pants, similar to Shins appearance.

Personality
Not much is known about him, but he's a decently laid back guy when it comes to most things, especially adorable things such as Ko's kitten Saburo. But, despite his goofy and adorable nature, he has a violent side and had no hesitation getting violent when he has to.

Abilities
So far, we haven't quite seen him weaponize his blood per se, but he can very easily manipulate his blood to the point where it can be used as a weapon, such as transferring his blood into the ground and the blood popping back up as multiple hardened blood spikes.
