Anessa is a supporting character in the anime My Daughter Left the Nest and Returned an S-Rank Adventurer, where she serves as a member of Angeline's adventuring party. As an archer, she provides ranged support for the group, complementing the combat styles of her companions. Her appearance is that of a teenage girl with brown hair cut to neck length and brown eyes, and she is often seen wearing a coat along with a bow accessory.

Within the party dynamic, Anessa naturally takes on the role of an older sister figure, particularly toward the beast-kin Miriam and the protagonist Angeline. She is portrayed as someone who is free from the prejudices common in her world, treating beast-kin like Miriam with the same respect and fairness as anyone else. This open-mindedness is a defining aspect of her character, allowing her to form genuine bonds with her adventuring companions without the social barriers that exist in their society.

Beyond her immediate party, Anessa holds a deep respect for Belgrieve, Angeline's adoptive father. She sees him as a father figure, drawn to his characteristic kindness and his gentle yet steadfast dedication to the well-being of those around him. This perception speaks to Belgrieve's far-reaching reputation and the warmth he extends to his daughter's friends, who become part of his extended family in turn.

In terms of abilities, Anessa is a skilled archer whose talents are crucial to the party's success in the field. She is more than capable in combat situations, as demonstrated when she effortlessly defeats a self-proclaimed strong adventurer named Gort the Thunderbolt. This victory not only showcases her individual combat prowess but also serves to highlight the high rank and considerable skill level that her entire party possesses. As the story progresses, Anessa, along with Angeline and Miriam, prepares to officially expand their party into a quartet, indicating her ongoing role as a core member of the adventuring group.
