Reiner's father

A Marleyan. He had a relationship with Karina, who worked at a certain barracks, resulting in the birth of Reiner. He appeared at the parade after Reiner inherited the "Armored Titan" and later met him, but he had already established another family outside the internment zone. He fiercely rejected his own child, Reiner, claiming that Karina had turned Reiner into a "Marleyan Warrior" for revenge.
