At the elite school known as Slave Academy, gifted education was carried out day and night through the strict discipline of special teachers. To uncover the school’s dark secrets, special investigator Mikoto Mine was sent from the Board of Education and went undercover as a teacher, fighting as Moretsu Kamen to protect the students. One day, a bounty hunter called the Beast Teacher, hired by Mr. Ghost, the school principal who ruled the academy, arrived to take up his post. Moretsu Kamen fought the Beast Teacher to protect the struggling students, but was overpowered. Then, during a batting drill by the corrupt baseball club adviser Kiyohara, a hard ball struck her body and knocked her unconscious. Captured, Moretsu Kamen was covered in a deadly cobra poison mixture… Bound and assaulted, she was pushed to her limits and had her mask torn away, exposing her true face, but she kept resisting to the very end. In time, the cobra poison began to take effect throughout her body, and she writhed in agony before finally dying. [BAD END]
