An underclassman of Nee-san, Hazuki is one of the members of the Model Club, nicknamed "Okappa" (オカッパ, "bob cut"). She is a classmate of Makimaki and sits next to her in class. She is generally levelheaded and calm but is prone to getting really violent and monstrous when it comes to Nee-san's antics. Still, she is shown to have a gentle and caring side when Makimaki was experiencing a heartbreak. She is weak against insects, especially large cockroaches. She has a model of a train on her head.
