Fritz, a seasoned senior soldier in the Wahrheit Imperial Army’s Zeroth Platoon, commands Leocadio Wöhler as his direct subordinate and shares a familial bond with his late brother Seitz. Answering to platoon captain Helman, Fritz navigates military obligations with disciplined precision. When their mission to transport a prisoner intersects with the smuggling organization Headkeeper, a violent clash ensues, resulting in Seitz’s death. Subsequently, Fritz and Leocadio are tasked with tracking down Sissel Grauer, sister of Innumael Grauer—a key figure tied to the smuggling operation.

Fritz’s actions consistently align with imperial protocols, prioritizing hierarchy and duty above personal sentiment. His brother’s demise introduces a private stake in his service, though his grief remains unvoiced. The character’s identity is anchored in his military role, shaped by tactical assignments and interactions within the Zeroth Platoon, without deviation into personal backstory or external narrative exploration.
