Ringo Noyamano is the female protagonist and Ikki's childhood friend and a member of the Noyamano family that adopted Ikki into their household. However, behind her seemingly plain and unimpressive guise of a junior high school student, she is actually the successor and leader of the legendary team, Sleeping Forest. She is the current Thorn Queen of the eight 'Kings' in the AT world. She helps Kogarasumaru in times of trouble, under the guise of Croissant Mask, "Kogarasumaru's No. 1 Supporter", though Agito and Simca know who it is.
