- "Empty texts are annoying, you know. If you've got something on your mind, I'm here to listen. Because you and I are always connected."
- —Natsuki to Fuuka in a text message, Persona 3 The Movie
Before the full moon mission, she is a rough, cruel, and mean student. Natsuki and her friends had taken up bullying Fuuka Yamagishi, locking her in the school gym at night.
After the Full Moon mission is complete, Natsuki is remorseful of her actions and changes for the better, and befriends Fuuka out of genuine kindness.
Natsuki Moriyama first appears as one of a group of girls who have been bullying Fuuka Yamagishi. Shortly before the third full moon on June 8th, she relates to the party and Mr. Ekoda that the girls had locked Fuuka inside the gym overnight, but when they went to to retrieve her, Fuuka had disappeared. A rumor spreads between Natsuki's group that Fuuka escaped and killed herself by suicide, and in fear of being in trouble for potentially bullying Fuuka to the point of suicide, Natsuki's group searches for Fukka to no avail.
During the Dark Hour on the night that SEES went to rescue Fuuka, a Shadow's voice in her head called out to her, luring her to Tartarus. The Shadow summoning Natsuki is the reason why Natsuki wasn't transmogrified. After the shadows are defeated, Natsuki apologizes to Fuuka for harassing her. The two later become friends, though Natsuki had forgotten about Fuuka saving her life in Tartarus.
Thanks to Natsuki, Fuuka becomes stronger and more optimistic, which her fellow dorm mates notice quickly. Natsuki often studies and goes shopping with Fuuka, and they go to the movies together during the Film Festival. Later in the game, Mr. Ekoda announces that Natsuki is transferring because her father is ill and they cannot afford to stay in town. She tells Fuuka that no matter how far away they may be from one another, they will always be friends. Fuuka's Persona then evolves into Juno, and Yukari and the others find her on the school roof after Natsuki leaves. She compares Junpei's situation with Chidori to hers with Natsuki's: even if they are apart, they are together.
Near the end of the game, Natsuki is seen encouraging Fuuka during The Fall as she remembers Fuuka had saved her in the past.
- Strangely, in the game she is always seen wearing her summer school uniform in school, but in the manga and movie adaption, she wears her winter school uniform during the spring and fall.
