Lanzhu Zhong is a second-year transfer student to Nijigasaki High School from Hong Kong, fluent in Mandarin and Cantonese. As the daughter of the school chairwoman, she commands significant influence and resources, which she initially leverages to pursue her goals. She shares a childhood friendship with student council president Shioriko Mifune and applied to Nijigasaki alongside her close friend Mia Taylor. Recognized as exceptionally gifted across multiple fields from a young age, Lanzhu's reputation fostered insecurity and isolation, hindering equal peer relationships. Her personality blends charisma with demanding expectations, driving her to push others toward excellence, though her methods often manifest as perceived arrogance or insensitivity. Within the *School Idol Festival All Stars* narrative, she founded the "School Idol Association," banning the existing School Idol Club to compel its members into her group. She employed professionals to elevate performances and used monitors to enforce rules, creating significant conflict. Her anime philosophy diverges slightly, emphasizing that idols should inspire audiences rather than rely on audience support. This belief leads her to operate independently, contrasting with but not directly interfering in the School Idol Club's activities. Her initial antagonism softens over time, particularly after the Association disbands. In Chapter 29 of *All Stars*, she apologizes for her actions, reconciles with the protagonist, and officially joins the School Idol Club as its 12th school idol alongside Mia. Anime development depicts her struggle with social integration due to fears of exclusion. An episode focuses on her gradual acceptance of friendship through club member support, culminating in group activity participation. The *Final Chapter* film trilogy introduces a new arc involving her mother, who sponsors the School Idol Grand Prix. Lanzhu initially misinterprets her mother's intentions as unethical advantages, prompting her to temporarily distance herself to ensure fair competition with her friends, exploring their relationship dynamics and Lanzhu's commitment to equitable artistic expression. Physically, Lanzhu possesses long pink-gold hair styled in high-looped pigtails in the anime, light greyish-blue eyes, and a distinctive beauty mark under her right eye. Her image color is pink-gold, reflected in her penlight and symbolic representations. She stands 165 cm tall with measurements of 87-55-82 cm. Her birthday is February 15 (Aquarius), her blood type is B, and she favors meat-based foods. Her Chinese name is written as 鐘嵐珠, with the surname "鐘" noted as non-standard compared to the conventional "鍾". She stylizes her signature as "L'ange," meaning "the angel" in French. Lanzhu is recognized as the first Love Live! character to perform trilingual songs and shares poor cooking skills with fellow member Setsuna.
