A girl who always fights and teases Suzume a lot. She has an aggressive attitude, as she has a mixed martial arts and professional wrestling background. But she aspires to be a singing star, just like her idol, Hatoko Daikan'yama. Her Pata-Pi is Tetsurou or Tetsu for short, an equally aggressive one who has built-in microphones, whenever she has the urge to sing, and a camera; it transforms into the Diva Athena. Tsugumi's name literally means thrush.
