Ienai Koto The Animation

Rena Hayakawa is a responsible and exemplary school counselor. By chance, she catches her younger sister, Mina Hayakawa, engaging in a carnal relationship with a male teacher right at school. Intending to intervene to protect her sister, Rena ironically falls into a cruel blackmail trap herself.

Backed into a corner to protect her family’s honor and her sister’s future, Rena is left with no choice but to submit and become a ‘plaything’ for corrupt men. These unspeakable secrets begin to submerge the Hayakawa sisters into a downward spiral of humiliation and sinful pleasure.
