Valkenhayn is one of the Six Heroes and Rachel's elderly butler and trusted adviser who has served the Alucard family line for generations. He possesses a sharp wit and is concerned for Rachel's well-being. Valkenhayn seems to be worried about Rachel associating with things below her class (particularly Ragna, although others might apply), but he always acts in a sophisticated and gentlemanly manner. Before Ragna devices his final plan to save the world from looping itself in Central Fiction, Valkenhayn bids his ally a farewell and good luck. At the end of the series, Valkenhayn is last seen pouring a tea for Rachel's return. Valkenhayn was once partnered with Relius Clover as an assassin in the past, and initially tried to kill Rachel's father before changing his ways and working under him. His Drive, Werewolf, enables him to transform into a wolf.

Valkenhayn is a noble gentleman: polite and courteous in all situations. Being a butler, he is extremely devoted to Rachel and does whatever he can to assist and protect her. His demeanor, however, belies a savage side which is only seen during battle or when he is pushed to the brink of his anger. He uses a fighting style that, while awe-inspiring, is unbelievably brutal, utilizing slashing attacks and blows so powerful they look like they are intended to break the enemy’s bones.

Despite his calm behavior, he tends to lose his temper every time Terumi is concerned, whether it be when Rachel talks about it or when he fights him. He also holds such animosity anyone who dares to be rude to Rachel, especially Ragna the Bloodedge; however, it was shown that he eventually puts trust in him along with the rest despite his prior doubts during the events of Central Fiction.
