Mitabi Jarnach was a team leader and member of the Garrison Regiment stationed in the Trost District. He was one of the Garrison's top three elite soldiers, alongside Ian Dietrich and Rico Brzenska, and played a critical role during the Battle of Trost District when humanity made its desperate attempt to recapture lost territory. 

Mitabi was a soldier of medium build with a short crop of brown hair and a very short beard that framed his face. His tannish, light-colored eyes gave him a somewhat weary and tense look, fitting his cautious nature. Like his comrades, he wore the standard Garrison uniform, accompanied by a green undershirt beneath the jacket. Though not as physically striking as Ian or Rico, Mitabi’s hardened expression reflected his years of service on the frontlines. 

Mitabi’s demeanor was marked by nervousness and caution, often making him appear doubtful in tense moments. He was usually seen alongside Ian and Rico, forming a trio of experienced soldiers tasked with guiding the mission to retake Trost. Despite his fearful exterior, Mitabi was not a coward. In fact, he displayed courage in the face of death, willingly luring a group of Titans away from Eren Yeager as the latter carried the massive boulder to seal Trost’s gate. This act revealed Mitabi’s selfless resolve—his fear was real, but so was his determination to protect humanity. 

Battle of Trost District (Year 845):

When the Colossal Titan breached Trost, Mitabi was among the elite soldiers chosen by Commander Dot Pyxis to carry out the dangerous mission to seal the gate. As Eren transformed into a Titan to move the boulder, Mitabi and his comrades were responsible for distracting and holding off incoming Titans. Though initially hesitant and terrified at the scale of the task, Mitabi rose to the occasion. He risked his life by shouting at Titans, diverting them from Eren’s path. His contribution, though less celebrated, was vital in ensuring the success of the mission.
