“A wrestling match turned forbidden: When a sibling rivalry meets a chemical mistake.”

A brother tricks his strong-willed older sister into drinking an aphrodisiac, claiming it’s just a standard energy drink. When the effects begin to take hold, she confronts him, leading to a heated physical struggle. However, as they wrestle, her chemically sensitized body begins to react to his touch. This 150-minute feature directed by Masahiro Kasahara explores the transition from a sibling conflict to an intense, uncontrollable climax.
