In the mountains, rumors spread among high school girls about a series of scissor-wielding serial killers. Never did she expect to become a victim herself. The scissor-wielding attacker, eyes fixed on Yumeru, says, "Sorry, but anyone would have done. You just happened to catch my eye. I'm going to test-cut you." The sound of scissors cutting through fabric echoes. Her favorite uniform, her scarf matching her friends', everything is ruthlessly cut away. Fear grips her, wondering what precious item will be cut next. "You're really scared, aren't you? That's good." Her uniform, pantyhose, underwear are all cut off.
