Since she was a kid, Lanzhu was treated as a gifted girl due to her noticeable talents in many fields.

In Chapter 29, Lanzhu apologizes to the Protagonist about her previous actions and officially joins the School Club as its 13th member and 12th school idol alongside Mia. She initially banned the Club in order to force its members to join the Association but later allowed it to exist again in parallel with it until the latter's subsequent dissolution in Chapter 28. She was first introduced in Chapter 19 of the All Stars story and since Chapter 20, she is the leader of the Association, which she created as a way to help the members of the Club, which she admires greatly, to improve by working with professionals she hired. She is childhood friends with the current student council president, Shioriko Mifune. Lanzhu applied to Nijigasaki with her good friend Mia Taylor.
