The eleven-year-old advisor of Class 1-C and the school's mathematics teacher. Becky was born to an American father and a Japanese mother. She's often cool and collected, but in scary or uncomfortable situations, she acts like a kid her age — immature, spoiled, and quick to hide behind a curtain and cry like the little kid she is at the first sign of trouble.
Cry Cute: Whenever she gets scared, pressured and/or scolded by her students (usually by Rei), she becomes Super-Deformed, and hides behind a curtain and breaks down crying like the eleven-year-old kid she is; so cute indeed that Himeko even called it the "Hau-Hau".
Jerk with a Heart of Gold: She frequently threatens bodily harm to anyone in order to enforce order. She's often the first to try to put Becky in her place should she go too far, but is also the first to try to lure her out should she end up going Cry Cute.
Mega Twintails: Sometimes Becky refers to Sayaka as "ribbon-head" due to her hairstyle - giant pigtails tied with two large white ribbons.
Mistaken for Gay: She likes Igarashi-sensei, and the girls of Class 1-C initially assumed she was in love. Turns out her feelings were more about admiration. Then Episode 15 shows a brief moment with Himeko, and Episode 17 shows her handcuffing Miyako so they won't get separated, although some of her classmates suspect something else.
Na´ve Everygirl: To the point that some of her classmates exploit her naivete.
The Generic Girl: Average in both appearance, academics and sports, although leaning more toward the latter, evidenced by her participating in a basketball tournament in the manga, as well as running in Episode 8. Rebecca calls her "boring girl" when she can't remember her name.
Genki Girl: Definately has signs of this, as she's seen only trailing Himeko in being quite happy.
Meido: Works at a Maid Cafe... whose sales aren't doing well because of her presence.
Murder Is the Best Solution: In the first episode, she repeatedly tries to poison Becky, insisting that this will solve everything. Rei, being Rei, picks up on this immediately and decides to have Ichijou taken out of the episode. She ends up killing Mesousa instead. In another episode, it's also implied that she killed a girl who was spying on Becky.
