Higashijuujou, Tsugumi

東十条つぐみ

A girl who constantly fights and teases Suzume. She displays an aggressive demeanor, stemming from her background in mixed martial arts and professional wrestling. However, she dreams of becoming a singing star, following in the footsteps of her idol, Hatoko Daikan'yama. Her Pata-Pi is Tetsuro (テツロー Tetsurō), or Tetsu for short, who is equally aggressive. He features built-in microphones for when she feels the urge to sing, as well as a camera, and transforms into the Diva Athena. The name Tsugumi literally translates to thrush.
