Holger has light hair which hangs down in front of his eyes. He can be seen wearing a dark coat over a light dress shirt, and long pants.
Following Eren Yeager's arrest for disobeying orders, Holger is among the soldiers who leak the news of Eren's detainment to the press to pressure the military into releasing him. After they are caught, the perpetrators are all arrested and Hange Zoë says they will be prosecuted.
The rebels are freed from their cells by guards who have also sided with Eren and rendezvous with Eren himself outside of the city. Eren declares that their next objective will be to find and team up with Zeke.
The group receives word from a Marleyan that Hange has arrived at the restaurant he is working at and storm the restaurant to capture her and the other Survey Corps officers that are with her. When Hange refuses to tell them where Zeke is, they take all of the officers captive and depart for Shiganshina District.
