Konomi Shinkaki attends Kiraragaoka Middle School alongside classmate Mirai Momoyama. She often spends time with friends Hokuto Imozaki and Tamaki Kurihara. Her appearance features sharp dark green eyes and short persimmon-colored hair, typically accented by a pale beige beret bearing a pastel green bow on its side. Her name reflects her design: "Shinkaki" merges the characters for "new" (新) and "persimmon" (柿), directly alluding to her hair hue, while "Konomi" (このみ), rendered in hiragana, holds potential interpretations like "choice" or "fruit".
