Anya

Anya is a short young girl with fair skin and emerald green eyes. At the time of their first meeting, Loid describes her as appearing about four to five years old at the oldest. Anya's eyes are large and oval-shaped, with prominent eyelashes. She has shoulder-length, light pink hair that curls inwards with a fringe that reaches just above her eyes and a small strand of ahoge at the top of her head. Anya is noticeably shorter than most of her peers, and many of the insults that Damian and his friends direct at her target her small size. However, in Damian's view, she gains a prettier appearance.

When Loid met Anya for the first time in the orphanage, she wore a simple black dress with a white ribbon at the front, along with white folded-down socks and black shoes. Anya usually wears this outfit when at home. She also wears two black hair ornaments with bright yellow embellishments resembling small horns on the sides of her head. Anya is rarely seen without her hair ornaments, even wearing them to sleep. The only other times where she is shown to not be wearing them were in her past and at the end-of-class gala, in which her hair is tied into small buns in place of the ornaments.

At Eden Academy, Anya wears the standard uniform with white knee-high socks and black Mary Janes. She carries around a brown schoolbag with a sheep keychain attached. During physical education class, Anya ties her hair back with a red headband when wearing the school gym uniform, along with white socks and gym shoes.

When she was younger, her hair was slightly shorter and wore clothing that resembled scrubs. As a young child, Anya is very impressionable towards the people around her. For instance, reading Loid's mind and attempting to mimic him, and learning how to punch from Yor. Given her telepathic ability, which ostracized her from people and her many foster homes, Anya instantly took to "Twilight" for being a real spy. Since being adopted, she wanted to go wherever he was going in hopes of seeing the spy stuff she always sees on TV. However, shortly after being adopted by Loid, she learns of the harshness of espionage and does her best not to interfere with his spy work. Despite this, Anya enjoys spy cartoons, her favorite being Spy Wars, and is often seen watching it whenever she can. Anya also finds excitement in Loid and Yor's secret jobs and identities. Anya is quite clever, being able to spell long words by herself and helping Loid out as best she can, even nudging Loid and Yor together. Anya is shown to understand complex certain situations and what solutions are necessary but not the more abstract parts of it. For example, she comes up with clever plans to befriend Damian, the second son of Loid's target, in order to help Loid's mission. She has attempted to help him with an art project and use her dog, Bond, as bait for an invitation to his house after reading his mind and learning he loves dogs. However, she failed to realize that her lack of art skills was not only not helping him but actually making him hate her more, or the fact that a kid who has repeatedly expressed his intense disdain for her would effortlessly become her best friend because they both have dogs.
