Anju Shiratori is a premier top idol affiliated with iL'ange in the Kiratto Pri☆Chan universe. She has fair skin, long white hair typically styled with off-center bangs brushed to the left, and striking blue eyes. When out in public as a non-idol, she often wears disguises such as sunglasses, though her signature hairstyle usually remains visible. A notable phenomenon is the consistent appearance of glitter and sparkles wherever she goes, which tend to linger long after she leaves. Her personality is elegant, poised, self-assured, and approachable, with a strong curiosity about everyday life and younger idols. She enjoys hands-on interactions, actively seeks new experiences, and often wanders towns to engage in spontaneous activities, occasionally evading her bodyguards until they track her down. Her hobbies include traveling. As a child, she was mentored by Aira Nanahoshi at Kirajuku Fureai Park, where Aira introduced her to PriChan, designed coords for her, and encouraged her to enter the Designers Full Cup, which helped catalyze her evolution as an idol. She recognized Mirai Momoyama’s potential after witnessing Mirai comfort a crying baby. Her mascot and assistant is named HakucCHO, a name derived from the alternative reading of her surname Shiratori, meaning swan. Over the course of the series, she temporarily retired from PriChan due to shifting interests but returned after competing in the Next Princess Special Tournament to seek a successor. In Season 2, she adopted the secret identity Phoenix Mask to anonymously join events, continuing her pattern of flimsy disguises. In Season 3, she vies for the Illuminage Queen title and the Castle Coord at PriChan Land’s Princess Cup, using the PriTama GO device to nurture her mascot. She performs in the unit iL’ange alongside Aira Nanahoshi, with songs including Perfect・Finale and Fortune・Carat. Her signature coords include her debut Pri☆Chan Uniform Pure White Coord, the Precious Muse Kiratto Coord, her favored iL’ange White Kiratto Coord, and the Hope White Jewel Coord, which was her first Jewel Coord. She was the third idol to obtain a colored Jewel Coord on her first Jewel Chance. Her birthday is November 11, known as Jewel Day in Japan, and she shares this birthdate with Seira Otoshiro and Bell Renjoji. Her age is not disclosed. Her surname Shiratori combines the characters for white and bird, while her given name Anju echoes the French word ange, meaning angel.
