Personality
Jakob is a dutiful butler who serves Tsubaki. On top of being great at housework and other chores, he is an excellent fighter. According to Tsubaki however, this was not always the case. It was because of Tsubaki's strong belief in him that he continued to remain in services. He is dutiful, kind, and courteous to Tsubaki when speaking to her. He has an undying loyalty towards her to the point he often ends up getting into verbal spats for Tsubaki's care taking. Due to this relationship,he ends up developing feelings for but thinks to himself that such a thing is wrong, because Tsubaki is his superior and Lady.

However, around other characters in the series he can be rather unsociable, speaking very rudely and bluntly to them. He sometimes speaks to others purely for the sake of making fun of them. He can be petty. Nonetheless, he still helps others when needed as part of his duty as Tsubaki's butler. He hates mornings.

History
Although born into aristocracy, Jakob lost connections with both of his parents, a fact that stems from them never loving him, never forging happy memories with him, and eventually abandoning him. Electing to follow Tsubaki regardless of the choices that she makes, Jakob attributes this to the kindness and compassion that she displayed towards him when he was alienated during his induction into the service of the Vampiric royalty, keeping him around despite his initial blunders.
