Some people have been mysteriously disappearing lately in your college: teachers, students, whatever is happening around it seems to be like it doesn't matter who you're, all the people around there always have a chance of disappearing. One day, you decided to help the professor Ratio in an investigation, little you know, that man isn't a human at all.
