An idol who previously performed under the stage name Yuka Kusakabe (草壁 ゆか Kusakabe Yuka). She unexpectedly retires from show business and enrolls herself at the Tamo Agricultural school. Unlike her idol persona, she, as Ringo, is more reserved and quiet. She is somewhat a rival of Minori for what seems to be Kōsaku's affection (she has called Minori a "Fat Ass" and a "Meddling Bug" in an episode while competing to plant rice in a rice field), yet they became on good terms after the incident. She appears to be conscious of her slender figure as the mention of her having small breasts can make her angry.
