Description
Aoi Miyasato is a character from the anime Valkyrie Drive: Mermaid, where she holds the position of a C-Class Liberator on Mermaid Island and serves as one of the Wärter Knights, a group tasked with maintaining order. Her physical appearance is notable for her deep tanned skin, shoulder-length black hair that hangs to one side, and brown eyes. She possesses a slender and toned figure, which contrasts with the more curvaceous build of her partner, Momoko Kouzuki.

In terms of personality, Aoi is remarkably laid-back and jocular, sharing a very relaxed attitude with her partner, Momoko. She has a playful nature, demonstrated when she was among the first to tease Mamori Tokonome about the misunderstood translation of her name. Aoi seems to enjoy shirking her duties, though she does so in a lighthearted and joking manner. For instance, when called to duty by Captain Kasumi Shigure, she answered the call but jokingly pretended not to be there. Despite this lackadaisical approach to her responsibilities, she does not fundamentally resist taking orders and dutifully reports when summoned. Her playful and teasing demeanor is also evident in her intimate interactions with her partner, Momoko.

Aoi's primary role in the story is as an initial obstacle for the protagonist, Mamori Tokonome. She and Momoko are the first pair Mamori encounters upon arriving on Mermaid Island. Initially appearing friendly, they soon reveal their aggressive intent, with Aoi, as a Liberator, stimulating Momoko, her Arm, to trigger their transformation. This encounter leads to a brief battle from which Mamori is rescued by Mirei Shikishima, resulting in Aoi and Momoko's defeat. Following this failure, they are shown being punished for their loss.

The core of Aoi's character is defined by her relationship with Momoko Kouzuki, who is her designated Arm. As a Liberator, Aoi's function is to arouse her partner, an Extar, to initiate a Drive, transforming Momoko into a powerful weapon, specifically a large gun. Their partnership is built on a shared, exceptionally relaxed and playful dynamic, and they are almost always seen together. They also have a professional relationship with Captain Kasumi Shigure, who has expressed displeasure with both of their attitudes as Knights, though they still respond to her commands. Aoi does not undergo significant development or change in the series, remaining a consistent secondary character with a defined, unchanging personality.

Aoi's notable ability is her role as a Liberator. This means she carries the A-Virus, which grants her the power to excite an Extar. Through intimate physical stimulation, she can trigger the Drive phenomenon, transforming her partner into a specialized weapon called a Liberator Arm. In combat, her function is to support by activating and likely wielding Momoko in her transformed state as a firearm.
