Himawari

A mysterious girl with a distinctive daisy-shaped hairpin. It's okay if you don't know who she is, you probably wouldn't remember her even if you met her. Her distinguishing feature is her ability to mimic other characters. She likes to work as a salesperson and watch what's going on from the rooftops. For unknown reasons, she sometimes helps Sensei with minor actions, indirectly influencing the course of events.
