Alright, here goes. I hope you don't mind me using Karina again, I sort of ran out of ideas by this point, derp. ^^;
Name: Karina Poirot
Personality: Karina is a shy one and prefers to stay out of the way, but she is friendly to those who actively try to get to know her, though her disability leaves her with a self-esteem problem. She's also something of a pervert, judging by the kind of manga she keeps hidden in her closet.
History: Karina was born Mute, so she always had trouble communicating with others and made it hard for her to make friends, especially when she had to move to a new city at an early age. However, she soon found people who were willing to be her friends and she's been grateful ever since.
Club: Electronics Club
Plans after highschool: She hopes to one day open an electronic's shop
Misc: Because of her problem, she usually communicates via text messaging.
