When school was over on the weekend, high school student Ayako walked out of the campus. After breaking up with her classmates, she walked home alone. Ayako couldn't hide her happiness at the thought of not having to go to class tomorrow. She could finally have fun for two days. She had to read the comics and TV series she needed to watch in these two days. When Ayako was about to reach home, she stopped suddenly when she passed a crossroads. Standing at the crossroads was a young woman with disheveled hair like a hungry wolf squatting on her prey.
