Love Live: Nijigasaki High School Idol Club: Rina Tennoji

 Rina is not good at conveying emotion and compensates for this with her "Rina-Chan Board", a sketchbook that she draws her emotions on.  When on stage she uses an electronic face mask that expresses the emotions for her.  She can be a bit shy but, is also very supportive.  Rina is very good with technology, math, and science; but, struggles with Japanese.
