Chiriko Tsurumi  

Tsuruko, 鶴見 知利子

As a kid, Chiriko was reserved and part of the Super Peace Busters club. Now she attends an exclusive school with Matsuyuki, where she ranks fourth in her class. She's serious, composed, and confident. When she first met Naruko, she belittled both her and her companions. However, after apologizing to Naruko, Chiriko has made amends. Despite the dissolution of the Super Peace Busters group following Menma's death, Chiriko and Matsuyuki have maintained their friendship.
