Onna kyôshi to oshiego: Zaimei, fujo, bôkô nari

Synopsis

A male student named Kenji Yamashita commits suicide at a high school in a town dominated by the local powerhouse Samejima family. It appears he was driven by overwhelming guilt after failing to stop his classmate and girlfriend, Kotaki, from being raped right before his eyes. However, Saki Kozai—Kenji’s homeroom teacher—finds the circumstances suspicious and sets out to uncover the truth. (Warning, exists in two different versions: the theatrical release is a pink film but the DVD release is an AV).
