On the surface, Zanka maintains a calm and composed exterior, a stark contrast to the chaotic, emotional turmoil he often experiences within. While he strives to present a placid demeanor, his volatile inner state of anger, disgust, or excitement can erupt in sudden outbursts. Despite his efforts to suppress emotions, he frequently gets caught up in the antics of his more playful teammates. As a former member of the noble Nijiku Family, Zanka carries a strong sense of pride without arrogance.
