In a Corner

A brief, ominous prequel that establishes the origins of a vengeful curse through an ordinary moment of schoolgirl vulnerability and abandonment.

Two schoolgirls, Hisayo Yoshida and Kanna Murakami, who are tasked with caring for their school's pet rabbits, are sweeping the cages and feeding the animals when Kanna cuts her hand, so Hisayo leaves her alone to go get bandages. (A prequel to the first version of Ju-on, 2000.)
