ケイ

Having too much strength since he was a boy, plus his love of fighting, led Kei to become a vampire hunter.
He always yells at the end of every sentence and has a bad habit of intimidating others.
At any rate, he has a foul mouth and scares women and children alike.
Of course, he’s foulmouthed towards the woman he loves too.
He has an athlete’s mentality, which makes him always fulfill his superiors’ orders.
