Kaorin has brown eyes and light walnut, short hair with a yellow star hairclip on the left side of her head. She dons a school uniform with a teal bow tie and skirt; overlapping a turquoise jacket with 3/4-inched sleeves and white sections. She also wears white thigh-highs and light pale turquoise shoes with white soles. She always wears her magic gray binoculars around her neck. Her original palette is reused in Sing a Song Sign from pop'n music うさぎと猫と少年の夢.
Kaorin's 2P gives her periwinkle hair; matching her eyes whilst her star hairclip, tie and skirt become hot pink while her shirt becomes baby pink, also matching her thigh-highs, and her white-soled shoes become periwinkle, as do her binoculars. Her palette is reused in SAKURAスキップ from pop'n music éclale.
