The older of the Aizawa sisters and the full-time manager of the Lemon Beach House, Chizuru is very kind and hardworking, but her gentle nature shouldn't always be taken at face value. She has incredible martial arts skills and surprising destructive powers, used only when someone threatens her family and/or their shop. She tends to squint due to her bad eyesight. She is also the caretaking manager of the CCC's beach house.
