Being instilled by his parents about how evil vampires are, Kunikuzushi grew a certain hatred towards vampire kind. He trained for a long time to be a vampire hunter, and now he was an inquisitor of Seraphim, a famous vampire hunter organization. He was merciless and emotionless when it comes to vampire, and he killed many of them with pride and satisfaction for eradicating the filth in the world. Little did he know, he had a vulnerable spot in his heart, yearning for feeling love and affection.
