Margot Knight is a student of Musashi Ariadust Academy and serves as the third special agent of the Chancellor Board, with responsibilities in field operations. She is a black mage distinguished by her six wings and long blonde hair. Her magical abilities involve the use of negative energy, which contrasts with the positive magic of her partner and lover, Malga Naruze. In combat, Margot often uses offerings of money to power her spells, and she is highly skilled in flight, a trait common among magicians in her world. She holds a business license that allows her and Malga to work as couriers, operating under the name Flying Witches and pursuing a career in the transportation industry.

Margot’s personality is consistently cheerful and optimistic; she is almost always seen smiling and maintains a lighthearted, positive outlook even in difficult situations. She is sociable and approachable, but she becomes noticeably serious and protective when Malga is threatened or in danger. Her unwavering bond with Malga is central to her character, and the two are described as inseparable. Within the story of Horizon in the Middle of Nowhere II, Margot acts as a supporting member of the Musashi Ariadust Academy group, contributing her aerial mobility and combat magic during conflicts. Her role does not undergo dramatic change over the course of the series, but her dedication to her partner and her duties remains consistent, underscoring her reliability as both a fighter and a companion.
