Blood Type: B Zodiac Sign: Taurus Rebecca, also referred to as "Becky" by her class, is the homeroom teacher of class 1-C and a mathematics teacher. She was born to an American father and a Japanese mother, although she keeps her mother's last name. Rebecca enrolled at MIT at the age of nine and graduated at ten with a triple major. She then entered Peach Moon Academy at age eleven as a teacher. Normally lethargic and halfhearted, she dons a cool face to keep her genius reputation. However, when confronted with a frightening or uncomfortable situation, she immediately reverts to her childish state, weeping uncontrollably (called the "hau hau" by the students in episode 21) and often hides behind a curtain. She is extremely popular and a confidante to the students.
