The youngest daughter of the Yamashita family, after losing her parents, grew up living alone with her four siblings, becoming a sexual plaything for her three older brothers from an early age. This documentary-style work was recorded and submitted by the second son, meticulously capturing the incestuous acts that occur in everyday situations—after shopping, in the bathroom, during bath time—all under one roof. The girl's development in this deeply twisted family environment is portrayed with raw realism. While addressing familial dynamics and social issues, this production faithfully recreates actual events. No performers under the age of 18 are featured.
