Nami is the true power broker behind the Shimazu clan, operating covertly through a puppet bearing a young girl's appearance despite her status as a grandmother figure. Possessing unrivaled strength within the family, she delights in playful pranks and teasing her juniors—even resorting to video games as an unconventional test of character. While she prefers to pull strings from the shadows, her influence shapes every major development, including actively nurturing the bond between the protagonist Shinichiro and her two granddaughters.
