Ann Kurimu is a middle school student and an idol affiliated with Million Agency, where she is part of the unit Lovely Marron. Her real name in kanji combines characters meaning "chestnut six" for Kurimu and "apricot" for Ann. She has a Western appearance with dark brown eyes, straight brows, and chest-length dark brown hair with loose bangs trimmed above the brows. Her signature hairstyle includes half twin tails adorned with accessories: a white teddy bear, a pink heart gem, a rainbow star hair band, and multiple clips such as lilac paw shapes, a strawberry, and a pink teddy bear. She typically wears her school uniform. In the virtual world Aikatsu Planet!, her avatar also goes by the name Ann, featuring round baby pink and blue eyes with long lashes and cotton-candy pink hair threaded with blue highlights. The avatar has wavy chest-length bangs with two high tied strands on each side. Ann's preferred Swing type is Sweets, and her key Dressia is Sweet Whole Cake. A notable contrast exists between the real world and the virtual one: Ann is taller than her senior Ayumi Tsukishiro in real life, but her avatar is shorter than Ayumi's avatar, Q-pit. Ann has a fluffy yet aggressively cute personality, maintaining an adorable demeanor even when annoyed. She is clingy toward those she feels close to, especially Ayumi, and can be jealous when others address Ayumi informally. Ann deeply admires Ayumi and aspires to match her skill level; out of respect, she refrains from using the familiar "-chan" for Ayumi, believing she must earn that right. She loves sweets, enjoys making them, and lists cooking, dessert preparation, and illustrating as specialties. Her hobbies include playing games. Ann debuted in episode six and performs in musical numbers such as "Happy Aikatsu!" and "Petit Price Everyday." She also appears in the film Aikatsu Planet! The Movie. Her birthday is February 15. She shares similarities with Kirara Hanazono from Aikatsu Stars! in hair color and fluffy personality.
