J-ker is from lomando and a schoolgirl. She looks like an ordinary schoolgirl with long black hair, wearing a yellow shirt (it could actually be white, with the lightning) which has rips on her left arm, a red tie, a blue skirt which is also ripped through the bottom, and black socks or shoes. Her body is entirely covered with blood splatters and her mouth is missing with her tongue sticking out. But she wears a mask for her mouth. On her tie is the letter "F", which is female for short.
