Asami Sato was trying to remember the path she took because she got lost in the forest. In the beginning, it was a sunny day but the weather changed so fast by six o'clock in the afternoon that she soon could not see more than a meter in front of her. She became worried after she figured out that, her cellphone was no longer working and Asami didn't know how to get home from that place. The forest was quiet and she was calm until she started to hear a strange noise in the dark. This forest was known as a habitat for small animals and also for larger carnivores. As she walked, she noticed the noise getting closer.
Her adventure became very dangerous, and just when she saw the cougar, an illegal hunter appeared and shot it in the head. Sometime before, she had gone through such a scary experience with the cougar, indeed, that Asami could not understand that the hunter was a murderer, a kind of psychopath who was trying to kill her. As a result, she was so grateful to be alive that she decided to help and support him. In the next decade, both murderers killed people who went alone into the forest until the day when both were hunted by a huge cougar.
