He is characterized by his gentle, drooping purple eyes and his 'Magical Purple' to ashen grey gradient two-tone hair. Unlike Kaiser, whose hair is dyed, Ness has had natural two-tone hair since childhood. Generally, he is a kind and gentle character who speaks politely. However, as a fervent follower of Michael Kaiser, he will threaten anyone who insults or obstructs Kaiser while maintaining a smiling face. His personality is very fragile, deeply affectionate, and he tends to cry easily. He is also somewhat naive and prone to trusting others easily, which is why he became Kaiser's loyal subject. He easily fell for Kaiser's seduction, which utilized applied psychology. Since childhood, he showed a childlike side with a rich sense of wonder and fantasies about magic. However, to his family, who pursued only scientific and realistic facts, Ness was an incomprehensible mutant-like existence and was constantly ignored and ridiculed. Perhaps because of this, even now that he is older, he still shows a childlike side that believes in magic. Separate from his fragile heart, he seems to have clear convictions or perhaps good mental resilience; despite being ignored by his family, he pushed through with what he wanted to do, and even after being verbally abused by Kaiser and losing heart, he quickly becomes lively again, showing a persistent and steadfast side.
