Nabiki is the second daughter of Soun Tendou. Her primary focus is on money, and she will go to great lengths to obtain it, even if it means blackmailing her own family members. In various stories, she plays a significant role in attempting to extort money or placing bets purely for her amusement.
Her personality is characterized by sarcasm, materialism, egotism, manipulation, sadism, and a complete lack of moral principles, which sharply contrasts with her older sister.
She can indeed be considered one of the most intelligent characters in both the manga and anime series.
