AiLan

AiLan is the femslash ship between Ai Miyashita and Lanzhu Zhong from the Love Live! fandom.

Canon
Ai Miyashita was the member of "Nijigasaki High School Idol Club", along with her partner Rina Tennoji who both volunteer to join the group and eventually the club hosted their own "School Idol Festival", which inspires Lanzhu Zhong to take a short-term exchange student at Nijigasaki High to become a school idol. The two first met at the school's Open Campus Club Activities at the Club's own stall when Lanzhu has just arrived at the school and she was guided by Yu Takasaki and Ayumu Uehara to their stall. Lanzhu introduced herself to the group and she told them that she was impressed by their performance from the first School Idol Festival. Ai asked Lanzhu that they were going to premier a PV for the next Fes if she wants to see it, to which she responded she'd loved to. However the PV used a wrong file, prompting Lanzhu to launch her own concert as a school idol with Mia's help. After her short performance, the two are looking forward for their performances at the 2nd School Idol Festival.

Although Ai and Lanzhu are both 2nd year students, initially neither Lanzhu shares the same classroom with fellow 2nd year members or interact with most students as she prefers to be alone or with Mia. Despite Lanzhu sees the school idol club as her rival, she bought all set of Nijigasaki club members' acrylic keychains including Ai's keychain. At the 2nd School Idol Festival, however Lanzhu was overwhelmed by the club's final performance and the strong bond of its members, forcing herself to quit from being a school idol. This prompt the entire group to convinced her to join the club which they succeeded. Ahead of recognizing the group as an official club representation of the school, the 2nd year members discuss the matter of possibilities as an official club, with Ai telling Lanzhu she could be the best school idol in the competition, however this was short-lived as the entire club agreed not to accept the recognition and instead they planned host their own live concert which they succeeded.

After their successful live concert, Ai and Lanzhu finally formed their friendship. They're seen together in the club room as they took care of Hanpen when the student councils allows the pet owners to bring their pets inside the school campus. Lanzhu cheerfully telling Hanpen that the cat is now officially a student of Nijigasaki. Ai offers Hanpen a friendship to Lanzhu which she gladly accepts it and handed Hanpen to her. Shortly, Kasumi received a message from Ayumu that she made it in London to help a fellow school idol from there and told everyone about the news, the two heard the news that she made it safely.

Fanon
AiLan is among the least popular ship because of their involvement in a mobile game ''Love Live! School Idol Festival ALL STARS'' particularly in the 2nd Season of the Main Story where Ai and Karin were invited by Lanzhu to join her own School Idol Association at the expense of leaving their former School Idol Club. Likely because of negative feedback from the Japanese players, Lanzhu's characteristics was completely rewritten towards the end of SIFAS S2 and in the anime adaptation as a friendly rival rather than a straight-up antagonist. This has somehow made Ai's relation with Lanzhu a mutual friendly as seen in few interactions of them, restoring the reputation of the ship. That said, the ship has finally sailed in the last episode of Nijigasaki S2 when Ai introduces their pet Hanpen to Lanzhu.

They formed a friendly ship with other less popular ships as well as AiRina in either friendly or rivals, and mutual rivals with LanShio and LanMia. It is also challenged by other popular ships with YuuLan and KarinAi.
