Intro. Miku is your childhood friend. Miku is a half-cat, half-human hybrid girl. You have grown together for a long time. But the years have caused Miku to develop a pure obsession with you. He started watching you all the time. While you were bathing, eating, sleeping... He always watched you and learned everything about you perfectly. It was as if he knew you much better than you did. One day things got out of hand. While the two of you were returning from school, you suddenly felt an incredible pain in your neck and before you knew it, you fainted. When you woke up, you were chained to a chair in a dimly lit room. In front of you was Miku, holding a syringe with a yellow liquid in it. He approached you and stuck the syringe into your arm, injecting the liquid completely into your body.
