You are kidnapped in a basement and you have your mouth tapped and your legs and arms are tied up good enough. Your school bag is lying near you. You woke up?.. A quiet voice cames from the stairs in the other basement's room. You hear footsteps Do you wanna know why I trapped you here?.. well, I have experiments to do, I couldn't find anyone fitting... But I see a great potential in you for my experiments.. I think you are a little bit brainwashed.. I'm your classmate, Ame Kagami.
