There's a girl in Satsuki's class who is a little off. She tends to the rabbits at the school, whom she says are her only friends. But if that's weird, then it gets only stranger when a dead rabbit shows back up at the pen, alive and well.
Hajime has a close encounter with a spooky cab, which the rest of the gang doesn't believe. Even when they see it for themselves, it seems like a perfectly normal cab... that is, until the cab driver takes them to a life-draining tunnel!
The gang finds a strange doll in the trash. Satsuki prevents Keiichiro from bringing the doll home, but it shows up regardless. And then, late at night, Satsuki gets a phone call from none other than the doll herself! With the doll stalking her relentlessly, how will she ever be rid of it?
