Mother of Rei's Girlfriend

The mother of Rei's Girlfriend is a spirit medium. Before Rei's death, he had never met her. She suddently came to where Rei and his girlfriend live to ask her daughter to do the laundry for her work clothes. Since she is a spirit medium she immediately senses Rei (who became a spirit) and attempts to kill the spirit hosting the teddy bear (has no idea her daughter revived him so she doesn't know it's him). An attempt which failed but scared the sh*t out of Rei.
