Ringo Noyamano is successor of Sleeping Forest and the Thorn Queen, of the Sonia Road. She is a second generation gravity child and the only one completely unaffected by pressure in the Trophaeum due to the pressure which the Sonia Road exerts on the user's body, leading to her being undefeated there. Her Sonia Road gives her graceful and deadly agility that eventually takes its toll on her body, except when inside of the 'forest' of Trophaeum. She is in love with Ikki, but she is unable to relay her feelings. This also makes it hard for her to fulfill her purpose as Sleeping Forest's leader while supporting Ikki. She helps Kogarasumaru in times of trouble under the guise of Croissant Mask, even coming to Kogarasumaru's aid when it was revealed that Ikki's negligence had prevented the team from registering.

She started out with a sisterly affection for Ikki, which eventually progressed to infatuation and eventually deep love, which she still tries to deny though it is clear to everyone except perhaps Ikki himself. Ringo has always let Ikki do things as he liked, turning an eye away during his gangster era as the leader of Eastside 'Undefeatable Babyface'. She is a pushover, her friends Emily and Yayoi easily manipulating her to doing things for them, and the teachers always picking on her rather than Ikki and gang.
