Misuzu Asahina is a character from the anime Bondage Game, also known as Bondage Game: Shinsou no Reijoutachi, and its sequel Shinsou no Dorei-tachi. She is a teenage girl with very long blonde hair, blue eyes, and a height of approximately 1.60 meters. She comes from a wealthy and influential financial family, a background that initially sets her apart from other characters.

Her role in the story begins when she is sent to a sadistic house of bondage, where she and other young women are forced to serve a master named Renji under strict and often cruel conditions. Within this environment, Misuzu undergoes training as a slave, adapting to the harsh rules and expectations placed upon her. Her motivations are largely shaped by her circumstances: survival and obedience become primary drivers, though her aristocratic upbringing sometimes contrasts with the degradation she endures.

In terms of key relationships, Misuzu is notably connected to another girl named Yayoi. In the narrative of the original game on which the anime is based, she can be obtained by trading Yayoi with a friend, indicating that relationships among the captives are transactional and that individuals are treated as commodities. This dynamic underscores the powerlessness and isolation she experiences.

Misuzu appears as a supporting character in the first Bondage Game OVA and takes on a more central role in the sequel. Her development is largely one of capitulation to the system; she becomes conditioned to her role as a trained slave, with her personality shaped by the constraints of the bondage house. She does not demonstrate any extraordinary physical or supernatural abilities; her attributes are primarily tied to her background and her transformation within the story. Her presence adds to the depiction of the series' themes of control, submission, and the corruption of privilege.
