The curse started when, due to the Extra, class 3-3 was carrying on as if there were more students in the class than there should be. This caused death to take notice of this seeming excess of living people and begin killing them. By shunning one classmate for a full school year the class goes back to acknowledging the 'correct' number of students, thus avoiding death's notice.
