She is a silent protagonist, as is the case with most Megami Tensei protagonists, although she does technically speak in battle when summoning a Persona and such.

Unlike the male protagonist or Megami Tensei protagonists in general, she is very bubbly, funny, upbeat, and cheerful. Her dialogue choices exhibit a broad spectrum of emotions, ranging from sarcasm, joking tones, utter seriousness, and otherwise depending on the player's choice. She is a sharp contrast to the male protagonist who is very reserved and concise where she, on the other hand, is not afraid to interject into conversations where her male counterpart would remain silent.

She is also said to be dependable and tough, just like how a leader should be. Although she seems to be always in high spirits, she hides her suffering and burden, which is why everyone, mostly Junpei Iori and Akihiko Sanada, worries so much about her.
