San Watanabe

San Watanabe is a student of 9 Grade Class 3 in 1998. She sits behind Izumi Akazawa in the classroom. She seemed to be a girl with a boyish, serious and mature personality. She is good friends with Kazue Satou. San was a minor part of class 3-3, not taking part in discussions about countermeasures and rarely involved with Kouichi Sakakibara or Izumi Akazawa's groups. San was one of the students present when Shoji Kubodera killed himself ( "Sphere Joint"), and was among those who fled the room in terror. Nonetheless, San decided to go on the class trip, willing to risk her life to break the curse; she shared a room with Yumi Ogura at the inn. San was among the students who heard Takako's broadcast, and left the room along with with Yumi. She was horrified when her roommate attacked Kouichi, but still caught her when he and Mei knocked her over while escaping. Unlike Yumi, San did not pursue the duo, instead attempting to escape the burning inn.
