A graduate of the 104th Cadet Corps wherein he graduated sixth of his year ranking below Eren. Hailing from the Trost District, he hopes to join the Military Police Regiment and earn the privilege of living in the Interior. While at the Cadet Corps, his belief that humanity cannot defeat the Titans constantly placed him at odds with Eren who fervently believed in the complete elimination of the Titans. Among the 104th, he is especially close to Marco who has a similar goal of joining the Military Police Regiment. While he is seen to be conceited and selfish at first, certain events will allow his skills as a leader to bloom.
