About
Blamuro is a vampire hunter who hunted Boris' ancestors 500 years ago, believing them to be, as descendants of the Count Dracula, to also be vampires. However, eventually they had enough, and the family succeeded in capturing him. They then tortured him until his sense of right and wrong was completely destroyed, and in turn also eradicating his personality, before killing him to serve as a Guardian Ghost to the family, who had learned to use shamanic abilities to become vampires.

History
500 years ago, the descendants of Vlad Tepes were still being hunted by people believing they were vampires. One of these hunters was Blamuro. However during this time Asakura Hao came and taught the family how to become real vampires by using Shamanic abilities.

The family succeeded in capturing Blamuro and kept torturing him until his senses was completely broken and there was nothing left of his spirit but a humble servant. It was then he was killed and became the guardian ghost of the family. 500 years later, the child Asakura Hao sought out the 22 year old Boris Tepes, the now living descendant of the Tepes family and the inheritor of Blamuro, who instantly swore him loyalty.

After a long fight with Yoh and his friends, Amidamaru was finally able to release his personality, which in turn made him stop serving Boris and he would eventually pass on to the afterlife.

Oversouls and Attacks

 * Possession: Boris bites an opponent and changes Blamuro medium to blood entering the new wound. This allows Blamuro to control the opponent's body anyway Boris wishes.

Anime/Manga Difference
In the anime, instead of being a spirit from 500 years ago, Blamuro is a now-living person who alongside other vampire hunters that hunt the last decedents of the Tepes Family, being Boris and his parents. Boris was able to escape with the help of his mother, however Blamuro succeeded in killing his parents who did not turn to dust, like a vampire should have. It is then that he finally realizes that they were plain humans and he started to search for Boris. However when he finally finds him, the now fully grown Boris, is together with Asakura Hao, and Blamuro is killed and stabbed. Also in the anime he serves Boris as a way to atone for his sins of killing humans.

In the 4Kids dub, his death was edited out because of the stabbing by Boris
