Kazuma Himura

Human Form
Kazuma is an eighteen year old boy with a fairly athletic body. He has long silver hair that is usually worn in a loose pony tail. His bangs are parted in the middle and go down a bit past his eyes. Close behind his bangs a couple of strands of hair stick out to the sides. His most noticed physical trait is his bright golden eyes and his one inch long fangs.

Half Transformation
Kazuma's demon form looks relatively the same except for a set of horns, two tails, a pair of wings, and dog-like ears. His horns are shaped kind of like rams horns and they are black in color.

Demon Form
In terms of size, Kazuma is known to be one of the biggest demons when he is in his demon form. He towers over humans like a strong and unyielding mountain. The combination of his two venomous snakes as tails and his razor sharp fangs is enough to frighten most humans.

In Kazuma's demon form his eyes are blood red and coming out of the corner of each eye are red lightning shaped-like marks. Above the lightning shaped markings are a pair of black dog ears. Behind the ears, are a pair of ram horns. The underside of the ram horns are black while the top of the ram horns is red.

Personality
Legends of Kazuma describe him as a bloodthirsty demon who will kill anyone who gets in Zeref's way. This is completely untrue for two reasons. The first reason is that Kazuma's job was to guard cattle, not Zeref himself. The second reason is because of the fact that he was overshadowed by his sister. This caused him to develop a rather lazy and carefree personality because he believed that no one was looking out for him to begin with. This of course means that his sister and his childhood is a very sensitive topic and a sure way to anger him quickly.

History
Most of what is known about Kazuma's past is simply dismissed as a myth or a legend. Kazuma was born in Kimotama City in the year of X673. During his childhood, Kazuma had few friends. His giant demon form and quick temper caused most kids and their parents to stay as far away from him as possible. On top of his quick temper, his magical power was very unstable, especially when he was angry.

His anger would always be followed by a tiny outburst of magical power. This outburst wasn't strong enough to do serious damage, but some kids were hurt. He did have a sister known as Cerberus, but by the time he was five she was already a mage and was only home once a year. As far as his parents were concerned, they treated him the same way everyone else treated him.

When Kazuma was ten years old he met the first person that was not afraid of him. Little did Kazuma know that this man was Zeref. The man never told him his name, but he instead he taught Kazuma how to control his magical power. Finally, Kazuma mastered the art of controlling his magical power when he was fourteen years old. When that happened, the man took Kazuma to a giant room that is hidden underground. He pointed to a cluster of red cattle and told him to make sure no one harmed them. Kazuma agreed as thanks for helping him control his power and giving him the resources to learn the magic he now knows.

Throughout his years of service he has fought a lot of enemies. Occasionally Zeref would send a mage to help Kazuma, but for the most part Kazuma fought alone. Everything changed for Kazuma four years later when he was eighteen years old. What started this change was a strong Devil Slayer named Hercules who said he would defeat Kazuma and take the cattle.

With that, the legendary battle began between two very powerful mages. In the beginning they looked equal in strength, but as the battle continued it looked as if Kazuma was actually going to win. He was too focused in the battle that he didn't sense a powerful Winter Magic mage sneaking up on him. When Kazuma had finally noticed the mage, it was too late. The mage had already touched him and put him in a cryostasis state.

As time passed on, most people began to view the story of Kazuma as only a myth. The few people who knew he existed, were power hungry and wanted to free and then tame Kazuma. Every one of those power hungry mages died a mysterious death. Many rumors were started regarding Kazuma's supposed death. Some believe that the Celestial Spirit King admired Kazuma so much that upon entering Cryostasis the Celestial Spirit King turned Kazuma's soul into a Celestial Spirit named Sirius. A lot of Celestial Wizards tried to find his key, but the key was never found. This fact caused many historians to believe that that rumor is false.

One day, 170 years later a man and a woman found a path that leads to the room where Kazuma was sealed. There were a lot of obstacles in the way, but they were able to get to Kazuma's location with ease. Once, they were there, the man used his powers over ice to unfreeze Kazuma from his long sleep.

His speed is incredible and it is speculated that he can run at speeds of up to 80 miles per hour or even a bit faster.

Demon Form and its seal
Kazuma's demon form is so big and powerful that his mother placed sealing tablets all over Kazuma's body when he was a child. These tablets restrain Kazuma's demon form and part of his power, if Kazuma were to ever try to enter his demon form, he would feel a choking like sensation around his neck. The only way Kazuma can enter his demon form is if he asks a Devil Slayer for permission. It also has been noted that no matter how strong Kazuma gets, it is impossible to take the tablets off of his body.
