Post Description

A horrible murder has been committed on the grounds of Nankai Academy. Professor Yuko, 
one of the school's most popular teachers, died when she was pushed off of the roof of 
one of the school's buildings. Her death has left her students with feelings of confusion, 
pain, and above all else... anger. Four of her male students, Masayoshi, Daisuke, Mitsuru 
and Shinya, are determined to uncover the truth. They soon discover an important clue: 
Professor Yuko's planner had been marked on the very night she was killed... marked with 
the names of seven girls.

With this evidence, the boys begin their investigations... and they'll use any method 
required in order to find the murderer. Through rape, manipulation and torture, they 
uncover important details, but piecing the puzzle together won't be easy. And the longer 
their search draws on, the more they feel themselves being overtaken by their own dark 
desires... Will they ever find out the truth behind Yuko's death?
