Appearance
Nac Tius had dark brown hair, which was styled back in a somewhat spiky pattern. He had medium brown eyes and was somewhat tall when compared to the average of the other trainees from his squad. He wore the typical uniform of a member of the 104th Trainees Squad with a grey shirt underneath.

104th Trainees Squad arc
Nac Tius is among the recruits of the 104th Trainees Squad. He is seen briefly talking to Jean Kirstein.

Battle of Trost District arc
Nac Tius graduates training as a member of the 104th Trainees Squad. After the second attack by the Colossus Titan, he is assigned to the middle guard including Eren Yeager and Armin Arlert in the Trost District. Shortly after the squad's deployment, the group is attacked by a Deviant Type Titan, which results in the death of Thomas Wagner.

This causes Eren to attack the Titan in a rage, which in turn causes his squad to pursue and try to help him. Another Titan jumps up and bites Eren's leg off and when Nac and Mylius Zeramuski are distracted, Mylius is grabbed by a Titan, which then eats him. Caught by another titan, Nac was then squeezed in its hand so hard in such a way that his lower body explodes. Armin would later report his demise to the remaining members of the 104th Trainees Squad, saying he died valiantly in the line of duty.

His death would later be avenged by Eren in his Titan form, who kills the Titan responsible for Nac's demise by punching and repeatedly stomping it into the ground after it attempted to kill Mikasa.

The Uprising arc
While speaking to Historia under the Reiss chapel, Eren mentions Nac as being among the victims he and Grisha Yeager are responsible for killing by stealing the Coordinate power.
