Natsuki is Fuuka's closest friend and a source of emotional support throughout the game. A Ganguro, Natsuki has an extremely tanned complexion and orange-ish hair, typical of most ganguro or gyaru styles. She displays a rather sadistic side and has a talent for analyzing people, knowing exactly what to say to make them feel worthless.
Initially, Fuuka was Natsuki's target due to her own insecurities. Drawn in by Fuuka's calls for help, Natsuki ventured into Tartarus. There, Fuuka saved her from a Shadow by summoning her Persona, which encased them in a protective shell. After this incident, Natsuki lost her memory of the event but apologized to Fuuka. The two quickly became best friends, with Natsuki's attitude positively influencing Fuuka, making her more confident.
Natsuki's father fell ill, and her family lacked the funds to cover the expenses, forcing them to move. Natsuki revealed that she and Fuuka were more similar than they thought, as her parents also neglected her, acting like she didn't exist.
Natsuki provided Fuuka with the resolve to earn her more powerful Persona by sending a text message saying, "No matter how far apart we may be, we will always be connected," which gave Fuuka the determination she needed. She also advised Fuuka, "If they don't accept you for who you are, then screw 'em."
Throughout the game, Natsuki remains the closest person to Fuuka, despite their differences. Natsuki also expressed, "I like you, even if you don't like yourself."
