Fritz (Figurehead)

Fritz (フリッツ) is the king, the person of officially the highest rank in the society within the Walls. However in reality he is just a puppet king who acts as a substitute for Lod Reiss, the real king.

The Uprising arc
Even though he has been talked about a lot before, his first appearance is during a conference with four other people, among them a member of the Military Police Brigade. Fritz does not wear his crown during this conference, but instead leaves it on the table beside him along with a bottle of alcohol.

Trivia

 * His first name is still unknown. He is only referred to as "the king from the Fritz royal family" (フリッツ王家).
