浅葱一子は悪喰である。

Furusawa Yuuka plays Kokkuri-san with three of her friends.
From that day on, her friends stop coming to school --
and she begins to hear footsteps creeping up behind her.
Amidst the growing unease, she encounters an upperclassman she has no memory of meeting before -- a mysterious figure with an uncanny presence.
“Shall I save you?” they ask.
