Appearance
Ulklin was a tall young man in his late teen years at the time of his death, with shaggy black hair and bright eyes just as his father had. He could be seen wearing a simple, light-colored robe, a dress shirt and a pair of black pants, as was common among men during Reiss family gatherings.

The Fall of Shiganshina arc
In the year 845, after the Fall of Wall Maria, Grisha Jaeger invaded the Reiss chapel, turned into a Titan, and killed most of Reiss family members, including Ulklin. According to Rod Reiss, he was "finally squeezed in Grisha's hand", while reaching out for his father.
