Born into a family immersed in Gunpla—her father a professional builder, her mother a professional fighter—Rindo Kuzunoha's life centered on the craft from childhood. Demonstrating exceptional talent, she secured a professional sponsorship contract while still attending Sokai High School. During her first year, she became the Gunpla club's ace and clinched the National Championship Singles title. By her second year, she rose to club captain.

Initially, Rindo maintained a reserved distance toward newcomers like the protagonist and Sana Miyama, perceiving them as inexperienced. This demeanor gradually shifted, revealing a more approachable and supportive nature, even toward those viewing her as a rival. Following Touma Aizen's departure, she became recognized as the club's second "brains," providing strategic insight and leadership. After graduating, Rindo continued honing her skills as a professional fighter, further refining her distinctive and polished battle style.

Her activities extended beyond competition. She participated in events like a superhero stage show, piloting a customized V08-1228 Grimgerde painted in Xvb-xd Farsia colors during a Gunpla Battle demonstration while wearing a pink rabbit suit. An earlier mistranslation in official materials incorrectly used male pronouns for her, later corrected.
