Lingyin Huang

Lingyin is depicted as a very energetic girl with a slight competitive streak. This is seen when Houki and Cecilia were arguing with Linying about her relationship with Ichika. She effectively answers them while hinting that she has an advantage over them (e.g. when Houki said that she has eaten and slept with Ichika when they were kids, Lingying said that he has been coming over to her place to do the same when they were in grade school). 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. When he asks what she means, she just says that it means she will give him free meals, hoping he would not understand the meaning. She can become extremely jealous when there are other girls around Ichika who are trying to get his attention, to the point of showing the stereotypical lifeless eyes of a "yandere" girlfriend (this trait is shared with Cecilia in episode 9 and at the end of episode 12). This trait is also showed at the end of episode 8, when Charlotte revealed that she was a girl. Lingyin crashed into the classroom and was immediately about to shoot Ichika with her Shenlong's Ryuhow without giving him time to deploy his own IS. To a certain extent, Lingyin has also become close friends (but still heated rivals) with Cecilia, compared to all the other girls. This relationship is analogous to Charlotte and Laura's close relationship in the light novels. This was proven in the anime when Lingyin (in a jealous state) offered to place sun tan oil on Cecilia's body in Ichika's place, and when the two worked together to spy on Ichika and Charlotte's "date" with Laura later tagging along with them. Lingyin is very sensitive when it comes her bust size. She can become easily enraged when her size is mocked or pointed out by others. Her friends are aware of this and don't talk about it (in the LN, Houki made it a point not to ever' complain about her large breasts in front of her). Strangely, she usually brings up this topic when she starts thinking about it or notice other girls' breasts. In Season 2 Episode 5, she became enraged and jealous when she saw Ichika look at Charlotte's breasts, believing he was only focused on them (Charlotte's breasts).
