Zanka Nijiku would describe himself as an "average joe" who was once arrogant but was humbled by a defeat, leading him to now rely on hard work to overcome those he sees as "geniuses". He is mentally strong, refuses to blame others, and dislikes pity, preferring to be cordial to "geniuses" while masking his deep-seated resentment towards their natural talents. Despite his past, he is driven and believes that "average" people can still become outstanding through sheer effort.
