Bram has a vampire-like appearance which includes having fangs. He has long wavy hair that reaches below his shoulders. He also has a distinctive triangular-shaped pointed ears similar to elven ears. Two scars can also be seen on his face, one on each side of his face, and there are distinct markings beneath his eyes. He has no lower body ever since Ōchi Fukuchi severed his head from his body, but a Holy Sword can be seen attached to his lower body.
Bram appears to have a disdain towards insolent people. After being dubbed as a calamity eight years ago, he decides not to add any more to his kin and finds no interest whatsoever in joining Fukuchi's scheme of inflicting the world with chaos. However, when threatened, Bram ends up obeying Fukuchi's orders regardless how much he does not wish to go against his personal vow of turning no one else into his kind.
Bram's ability name is currently unknown. However, it is an infection-type ability which turns whoever he bites into a vampire. It also makes the victim the next aggressor. The infection rate of the ability is fast, in which it surpasses the speed of the South American werewolf incident. According the governments of the world, Bram's ability is counted as one of the "Top Ten Calamities to Destroy the World", making his power one of the ten capable of destroying the world and causing wide scale death, destruction and chaos.
As seen with Akutagawa, it is possible that his ability also allows him to bring back the dead back to life by turning them into his "kin". 
In the past, Bram was an earl in Northern Europe. Despite formerly being a human, his cells had been mutated due to an ability, which then resulted in him being transformed into a blood-sucking species and known as "Dracula" (
Eight years ago, Bram became known as one of the "ten calamities to destroy mankind". At some point, he encountered and clashed with Fukuchi, resulting to the latter severing his lower body.

He is brought by Fukuchi, contained in a coffin, after Ryunosuke Akutagawa's death from their battle at the ship. After waking up, he asks Fukuchi how long has he been sleeping to which Fukuchi replies that it's been only two weeks. Just as he was about to go back to sleep, he is stopped by Fukuchi saying that the next time he wakes up, he will be busy. Bram replies that he doesn't know about it and tells Fukuchi that he is a being that sleeps much and recites that the insolent ones must be cursed. However, he is suddenly pulled up by Fukuchi, revealing that he has no lower body and only a sword is attached to him.
Fukuchi then cuts their conversation and tells Bram that he even prepared a meal for him as a sign that they are comrades. Hearing this, Bram glances at Akutagawa's body, but he declines. He tells Fukuchi that, eight years ago, he was dubbed as a calamity and for this, he no longer wants to add to his kin and will no longer drink his blood. He then further tells Fukuchi that if he wants to burn the world, he should do it himself instead.
Bram is then told by Fukuchi that as you age, you start to use people. Bram is seen struggling after Fukuchi tighly holds the handle of the sword which can make Bram's brain turn into ashes. Bram then shows his fangs and proceeds to bite Akutagawa.
Bram is seen again, waken up Fukuchi and orders him to bite Deputy Commissioner Yasui. However, in exchange of the plan being successful, he demands Fukuchi to give him a thing called "radio" since he states that it grows tedious in the coffin but before he even finishes his sentence, Fukuchi closes his coffin.
Michizō Tachihara catches Fukuchi's hidden identity and clashes with him, which ends with Fukuchi blinding Tachihara. Bram is later pulled out of his coffin once again by Fukuchi, who enlightens Tachihara about the Decay of Angels' primary targets, the politicians, whom Fukuchi deems must die painful deaths similar to angels. As such, their next step requires control over half of the world's nations, a feat which Bram estimates can be accomplished within four more days.
Tachihara believes it is not possible, only to recall that Fukuchi's ability can increase any weapon's efficiency by a hundredfold and thus make such task possible. As Fukuchi bids Tachihara to serve his commander again as a vampire, the mafioso slides out a blade and attempts to kill himself, but Fukuchi instantly stops him with his hands. Bram then bites Tachihara and turns him into his kind.
Later at an airport, Fukuchi shows Bram in his coffin to Saigiku Jōno. Bram reports to Fukuchi that half of the guards have now been turned into vampires, much to Jōno's confusion. Per Tachihara's previous words about how the Agency believes that a mastermind framed them, Fukuchi reveals to Jōno that he is the mastermind. He then invites Jōno to join him in carrying out his plans.
