Nobuaki Zenin is a deeply conceited, vain, and opportunistic individual who strictly enforces the rigid, traditional hierarchy of the Zenin Clan. As the captain of the Kukuru Unit, he displays an arrogant and condescending attitude, frequently looking down on his opponents—particularly Maki Zenin—due to his overinflated sense of superiority. Despite his stern, disciplined exterior and position of authority, Nobuaki is inherently self-serving; he routinely forces his subordinates to handle the hazardous, exhausting legwork of their missions while reserving key actions for himself so he can safely steal the glory and claim the credit.
