Personality
Timid and kind, Anzu is a hard-working, self-sacrificing young woman with a mischievous and tomboyish side to her. While she was made into a producer on a whim, she takes her job very seriously.

Coming from a strict and corrupt prep school, Anzu has a strong sense of justice, a quality that left her with no hesitation to help Trickstar carry out their revolution. Sharing their same desire for freedom and fairness, she’s rightfully described as their Goddess of Victory. Though she had turned into a gloomy, dejected person after the events of Paradise, she found new hope upon meeting idols, especially Trickstar. Her gratefulness towards idols manifests as the hard work and dedication that she puts in supporting them, sometimes to a fault; she often has to be reminded to take a break, and has gotten hospitalized from overworking multiple times.

Possibly as a consequence of the bullying that she suffered during her first year of high school, Anzu has a quiet presence and rarely speaks; when she does, it’s in a soft, gentle voice that often has people repeat what she just said. She remarks that she was never good at being self-assertive.

During Ensemble Stars!, she tends to have a playful attitude when interacting with other characters, often teasing or pranking them. She can sometimes go too far and resort to violence, something that the idols tend to point out.

Anzu doesn’t care much for her physical appearance, especially during her second year. She is usually seen wearing her school uniform or her PE clothes, and doesn’t wear make-up or perfume.

Appearance
Anzu is a girl with short, shoulder-length brown hair and light blue eyes. In the game, multiple characters imply that Anzu is of below average height, and Mitsuru notes that she is shorter than him. In the anime, she is shorter than Hajime.

During her second year, she wears a pink cardigan and Yumenosaki Academy's blue blazer over her Kimisaki Academy uniform, and wears tights. Although she wears a blue ribbon bow in the game, in the anime and the second manga, she wears a blue tie.

In Ensemble Stars!!, her hair is kept up in a ponytail.

Etymology
Anzu is the default name for the player. It is possibly derived from the game's title, "Ensemble Stars!" (Ansanburu Sutaazu), taking the An from Ansanburu and the zu from Sutaazu.

Similarly, her nickname in Ensemble Girls! was Angie, taking the An from Ansanburu and the G from Garusu.
