Noa Kuonji attends Yokohama Super Global High School and competes in skate-leading. He has slightly curly blond hair with tented bangs, auburn eyes, and a right-ear piercing. His training uniform pairs the school jacket and pants with a purple diagonal split top and black sneakers featuring yellow laces.

Previously ranked second in singles figure skating behind Reo Shinozaki, their rivalry continued when both transitioned to skate-leading. His name reflects his character: "Noa" combines characters for "dream, vision" and "sky," while "Kuonji" incorporates meanings of "eternity," "long time," "distant," and "temple."

During Grand Prix preliminaries, he led Yokohama Super Global against Kogahara High School for a finals berth. Prior to this match, he apologized to Kensei Maeshima and shared future goals, revealing a shift from self-centered motives to altruistic purposes in skate-leading. Earlier, he partnered with Kensei during a mandatory skate-leading badge test after both required certification.

He persistently urged Izumi Himekawa to observe an exhibition match between St. Clavis and Ionodai high schools, indicating interest in analyzing rivals like Shinozaki and Maeshima. His team's performance in the eighth Grand Prix preliminary was noted for unique choreography and significant effort.
