Jakob is a butler who serves Corrin in the Kingdom of Nohr. Although born into aristocracy, Jakob lost connections with both of his parents, a fact that, according to his supports with Azura, stems from them never loving him, never forging happy memories with him, and eventually abandoning him. Electing to follow Corrin regardless of the choice that they make, Jakob attributes this to the kindness and compassion that they displayed towards him when he was alienated during his induction into the service of the Nohrian royalty, keeping him around despite his initial blunders.

Jakob is a dutiful butler who serves Corrin. On top of being great at housework and other chores, he is an excellent fighter. According to his supports with Azura however, this was not always the case. It was because of Corrin's strong belief in him that he continued to remain in services. He is dutiful, kind, and courteous to Corrin when speaking to them. He has an undying loyalty towards them to the point he ends up getting into a verbal spat for Corrin's caretaking in his support chain with Camilla and even gets into a verbal battle with Frederick in the Before Awakening Xenologue on who serves their Lord/Lady better as a butler. Jakob's devotion is so strong that he, against his better judgement, aids Takumi in very dangerous archery practice just because refusing might disappoint Corrin.

However, around other members of the army 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 as shown in his support conversations with Silas. He can be petty, enough so that he becomes upset that his own son brews coffee better than he can and repeatedly challenges him until he can produce superior coffee. Nonetheless, he still helps others when needed as part of his duty as Corrin's butler. He hates mornings the most out of everyone in the army.
