Masami Shimomura is a supporting character in the anime ASaTTe DaNCE. She serves as the leader of an avant-garde drama troupe named Bondage Horse, a role that places her at the center of the theater activities that the protagonist Suekichi Terayama is involved with behind the scenes. Early in the story, Suekichi harbors a crush on her, though this initial romantic interest does not define her character beyond that point. Masami has a long-standing friendship with Daisuke Ikezu, a fellow character, and according to Ikezu, she is a twenty-seven year old virgin. This detail hints at her personal life and age, but little else is revealed about her background or motivations within the series. Her primary function in the narrative is as the leader of the theater troupe, and she does not undergo significant development or display notable special abilities. The available information about Masami Shimomura is limited, and she remains a relatively minor figure in the overall story.
