I like Sengoku-sensei. I liked that part of the 2nd Gatas magazine where she was tasting foods with Konno.
After seeing her in that Berryz vs. Berrys show as the robot 1059 "sen-go-ku" (going "PI-RI-RI" all the time), I was surprised at how short she was compared to the other members. She really fit in well.
