From a young age Naoya was always praised told by others that he was a genius. He is severely spoiled as the youngest and most promising of the Naobito's children, conditioned to view himself as his father's successor. As a result, Naoya's arrogance grew to unbridled levels. He looks down on all those he views as weaker than him. He confidently pursues strength. He is haughty, reckless, arrogant, assertive, prideful, traditional, practical, realistic, misogynistic, dominant, and conceited.
