In 1990, There was a church college called St. Michael Private College. This church was controversial. The sisters were extremely strict and would whip anyone who would talk behind their back. One of the sisters, Sister Yumiko was talking about Christianity and there was two girls who were whispering, Yamato and Aochi. Sister Yumiko heard them and whipped them. Later, there was a new transfer student that was late, Aiko Mimura. She ran to the college and ran inside of Sister Yumiko's classroom. Sister Yumiko was mad and slapped Aiko. Aiko then snickered. One of the girls in the Girls' Crusade team, Rika Ikeda, got a rope and told Aiko she violated the school rules. Aiko then got grabbed by the whole class and the class went somewhere else. The class then put her into the punishment room. It was dark. Aiko then got tied up at the ceiling. Will Aiko survive this evil private college? Let's see as we go back weeks earlier to St. Michael Private College.
