Vampire Hunters
Vampire Hunters are the enemies of vampires. They were created ten thousands year ago by one of the progenitors of the vampire race who desired to give humans a chance to defend themselves against the vampires that were turning the human race into their slaves. By drinking her blood deeply, she poisoned the humans, those who survived became Vampire Hunters who developed accelerated healing, the ability to sense vampires. They also are capable of using magic to detect and detain vampires. Only Vampire Hunters are capable of wielding anti-vampire weapons, such as swords and guns, that will only harm vampires and are the only weapons capable of killing the immortal Pureblood vampires. Their abilities were then passed on to their children, however as a result of sharing some vampire instincts, twins are rare, normally devouring each other in the womb and are stillborn. They set up an association of hunters with rules and regulations that they must follow in order to hunt vampires. The hunters maintain a list of vampires who have become dangerous and violated the rules as defined in the treaty with the vampires.
Headmaster Kaien Cross
Kaien Cross is over 200 years old, the oldest and most powerful known Vampire Hunter, nicknamed "The Fangless Vampire". In spite of being a vampire hunter, Kaien maintained friendships with several Pureblood vampire families, especially the Kurans. Kaien adopted Yuki and also took Zero into his home after he his parents were murdered by a Pureblood. Kaien retired as a vampire hunter and became the Headmaster of Cross Academy, he established the Day Class and Night Class with Kaname Kuran with dreams of promoting peace between humans and vampires. Kaien is an eccentric character who often provokes Zero and irritates other characters with his silly mannerisms, though he is a serious character when it comes to matters he cares about. He carries a hidden anti-vampire weapon in his cane which he uses to fight against the President of the Hunter Association who had turned corrupt from drinking Rido Kuran's blood. It is also pointed at, although never said directly, that he was in love with Juri Kuran.
After the one year time skip, he is not impressed by Kaname's rebellion against the rest of the Purebloods, and tells Zero that he will go to stop him. The hunters later reveal to Zero and Yuki that they think that he should just let Kaname do what he wants. Kaien and Kaname fight with swords, and Kaien tells him that he will never return Yuki to him, though she still believes in him somewhere in her heart, and that it is his turn to change her back into a human. When Kaien slashes Kaname, he is revealed to be Toma, who has been used by Kaname. Kaien carries Toma back to the Hunter's Association. When Zero brings Sara to the Hunter's Association, he thinks that Sara and Kaname killing each other is a sick joke.

Toga Yagari
Toga Yagari is currently the top ranked vampire hunter, as well as the one who trained Zero to be a Vampire Hunter. He lost his right eye trying to save Zero long ago when Zero's old school nurse turned out to be a Level E Vampire and tried to attack both Zero and Ichiru. Yagari told them to leave but in an attempt to help his teacher, Zero refuses and stays. It is during this time that the nurse goes for Zero, that Yagari stands in front of him and gets a blow to his face, losing his right eye. He appears at Cross Academy in the guise of being a new Ethics teacher for both the Day Class and the Night Class, but he's really there to see if Zero's become a Level E. One night when Zero tries to drink Yuki's blood, the two fall in a swimming pool and when the emerge from the water Yagari shoots Zero in the shoulder with an anti-vampire gun.
Later when Ichiru returns to confront Zero, they get in a fight. Yagari steps in, and to avoid Ichiru having his sword fall through his face Yagari stands over him and lets the sword fall through his own shoulder. Yagari is shocked to learn the Senate's decision to punish Zero for the death of Shizuka Hio and later reappears to arrest Zero. Yagari subsequently joins the Kaien Cross to protect Cross Academy from the Hunter Association. When Kaien goes to Kaname to stop him after the one year timeskip, he is angry at him and tells him that he should let Kamame kill the Purebloods.

Kaito Takamiya
Kaito Takamiya is a young hunter and a teacher-in-training. According to Kaien, Zero and Kaito share Yagari's attitude because they trained under him. Kaito was trained by Yagari with Ichiru and Zero after his former teacher was wounded. During that time, Kaito picked on Ichiru for his physical weakness and Zero for his soft heart. Later, Zero and Kaito become more friendly. He is a ruthless vampire hunter and trusts no one. His elder brother was bitten by a Pureblood and on his first mission with Yagari, he insisted on killing his brother himself. Kaito is invited to the academy by Kaien to be a student ethics teacher, while they are relying on his competence as a skilled hunter to assist the Hunter Association's organization. Kaito makes his own plans, inviting Yori to sneak into a vampire soiree, later revealing to Zero that it was to stir up the vampires as an excuse to hunt and as a test on Zero's control around them. He later reveals that his role is to observe Zero and invites Zero to rely on him as Zero once did on Yuki.
Zero orders Maria to take Hanadagi's servant to Taito, and he guards her with Hanabusa and Maria. Handiagi's servant is angry that the Vampire Hunters are letting Sara do what she wants, and Kaito agrees. At the Hunter's Association, she is angry that Sara is there with Zero, and Kaito tells her that she would get killed if she tried to attack Sara when Handagi's servant asks to be let free to kill her.
