Neyka is a member of the secret organization Libra in Blood Blockade Battlefront. She serves as the assistant to Patrick, Libra's arms craftsman and dealer. Neyka is a young woman with green eyes and light brown hair that she ties into a ponytail with an aqua-colored ribbon. She is the shortest member of Libra. Her background involves meeting Patrick during a conflict in an unspecified country; recognizing her talent for mechanics and weapons, Patrick offered her the chance to escape the conflict with him, and she accepted. As a character, Neyka is not shown to speak much, often remaining quiet and observant. She is highly skilled in her work, particularly with weapons and machinery, making her a valuable support member of Libra. A notable trait is her gluttony; on one occasion, she spent an entire Libra office party simply eating food. Her motivations are tied to her role as Patrick's assistant and her place within Libra, though her personal goals are not deeply explored. Her key relationship is with Patrick, whom she assists faithfully, and she interacts with other Libra members during missions. Neyka does not undergo significant personal development over the course of the series but remains a consistent and competent background figure. Her notable abilities include her mechanical and weapons expertise, which she uses to aid the organization.
