President of Blast's Private Fan Club and a long-time fan of Yasu since his days in Brute. She keeps in contact with Mai and divides the fans by their interests in the members. Her devotion to Yasu is unfailing and she relays any news outside of Gaia's influence to him. When questioned about her financial situation, she replied to have some dependency from her rich "father"—though he is not biological. First seen in the story as a bobcut-haired groupie, later as a platinum blonde during her late teens, and re-introduced with curled black hair as an adult; Shion's only constant traits include the mole underneath her left eye and the tattoo on her right arm.
