Huang Lingyin♀

Lingyin is a 1st year transfer student student in Class Two at IS Academy, the 2nd childhood friend of Ichika Orimura, IS Representative Candidate of China, and Class Representative of Class Two. Lingyin is depicted as a very energetic girl with a slight competitive streak. In her middle school year, she was usually the target for pranks due to her nationality. However, Ichika helped protect her from these situations (e.g. when he protected her from four school bullies). Because of this, she developed romantic interests for him and made him promise that if she became an excellent cook, he would become her boyfriend. When she meets Ichika again at IS Academy she becomes disappointed and extremely hostile to him because he had forgotten the details of the promise.
