Hiana

(ヒアナ) was a new recruit for the Survey Corps in the live-action film Attack on Titan. She was portrayed by Ayame Misaki.

Appearance
Hiana was a young woman with black hair, held in a ponytail that flows past her shoulders. She sported bangs that were parted to the right and cascaded down the sides of her face.

Personality
Hiana appeared to care very much about her daughter, as she joined the Survey Corps as a way to obtain child support and was saddened she was taken away. She was curious, running away from the squad to find the source of a cry she assumed was a baby. She appeared to have had a crush on Eren as she attempted to seduce him prior to her death.

Story
Hiana joined the Survey Corps as a way to obtain child support and first appears as a new recruit. She says goodbye to her daughter, but the two are separated. When the Scouts move out to Omatechi, she hears a cry and assumes it to be a baby. She wanders off, Eren accompanying her, and they discover the cry to be of an Infant Titan. When it fails to grab them, it lets out a scream that alerts Titans to their position.

Later, Hiana finds Eren screaming after he talked to Mikasa and Shikishima. She jokes if he is trying to call the Titans, but Eren apologizes. She says she should be the one apologizing. She takes him to an abandoned building to hide in for the night. She asks about what happened between him and Mikasa, and jokes that Eren acts like a little kid when he does not respond.

When Lil and Fukushi arrive and make out, Eren wonders if they'll marry, but Hiana says that its not right they need to seek permission to marry. Hiana says the reason she joined the Survey Corps was because she would be provided with child support. She attempts to seduce him, but as she tries to, a Titan breaks through and grabs Hiana, swallowing her whole. Her final word was "Riko," her daughter's name.

After Eren is swallowed by the Bloated Titan, he finds Hiana's dead body in its stomach. He is angered and horrified, vowing to kill them all. This awakens his Titan Shifting powers and allows him to burst out of the body of the Bloated Titan, exploding and killing it, avenging Hiana.
