Muchisute is a disfigured performer in a traveling circus, lacking both arms with his face entirely covered in bandages due to leprosy, though some adaptations depict him as a burn victim. This condition necessitates his reliance on his feet for daily tasks and specialized performances, most notably archery. His background prior to joining the circus remains largely undefined, though his arm loss occurred before his affiliation. Within the circus, he develops a predatory sexual fixation on Midori, a 12-year-old orphan forced into servitude. He participates actively in her near-daily physical, psychological, and sexual abuse alongside other performers. This includes molesting her, being present during a graphic threesome involving other circus members near her, and ultimately raping her, resulting in the loss of her virginity. His sadism is evident through his visible enjoyment when witnessing Midori subjected to violence by associates. His primary relationship outside this abuse is a consistent camaraderie with Akaza the Giant. Following the circus's financial collapse and the owner's abandonment, Muchisute attempts a manipulative reconciliation with Midori, offering a superficially apologetic plea for renewed friendship. This shift is motivated by a possessive desire to undermine her bond with the magician Masamitsu and regain control, not remorse. His actions directly lead to his demise; Masamitsu subjects him to a terrifying illusion before killing him via forced sand suffocation. Posthumously, Muchisute appears in Midori's hallucination alongside other deceased circus members, collectively mocking her descent into madness. His legacy is marked by his significant contribution to her psychological destruction. This characterization remains consistent across the original manga source material, the 1992 anime adaptation, and the 2016 live-action film regarding his core narrative role, physical attributes, abusive actions, and ultimate fate.
