Jakob

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. If he achieves an S-Support, Jakob will have a son named Dwyer.
