KuuKaa

KuuKaa is the femslash ship between Keke Tang and Kanon Shibuya from the Love Live! Superstar!! fandom.

Canon
Keke and Kanon are students at Yuigaoka Girls' High School as well as fellow school idols; the two were also the ones who founded Yuigaoka's School Idol Club, which eventually led to the formation of Liella!

Kanon is the protagonist of Love Live! Superstar!! and she is presented as someone that wishes to be a singer, but she is held back by the fact that she gets so nervous whenever she has to sing on stage, she can't bring herself to do it. Keke is a transfer student from Shanghai and she meets Kanon as she was singing while on her way to school. Kanon's voice amazes Keke, so she jump straight into asking her if she wants to be school idols together, though she does this is chinese, which confuses and scares Kanon away. Later in school, they properly meet each other and after a discussion with the school council president, Ren Hazuki, Kanon decides to help Keke find members for the school idol club, with little succes. Keke later askes Kanon again if she wants to do be a school idol with her, and though she initially refuses again, she ultimately runs back, feeling motivated by the fact someone wanted to encourage her to sing and her desire to keep doing just that, singing the insert song Mirai Yohou Hallelujah!, which surprises her, founding herself able to sing in public.

After forming Yuigaoka's School Idol Club, Keke and Kanon are met once again by the opposing Ren Hazuki, which doesn't want to allow their club activities, but the Director allows them to go forward with the club, as long as they can win an upcoming local school idol competition. With the help of Chisato Arashi, Kanon's childhood friend, they train their dancing and stamina together, which is specially hard for Keke, who isn't very fit. Still, she offers a great contribution lending her lyric notebook to Kanon, which inspires her to finish composing the song they will sing at the event.

Problems arrise again when Kanon is unable to sing in public again. Chisato and Keke try to help her, but to no avail. After that, Keke tells Kanon that, if she couldn't sing her part, she would sing the complete song herself. After that, she shows both Kanon and Chisato a huge sign she made for their event, featuring the name she gave to their group - KuuKaa, explaing she created it combining both of their names. Later in the day, Keke and Kanon are left alone in Keke's appartment as Chisato leaves. Seeing Kanon still upset, Keke tries to ask Chisato to join the group, thinking it could help cheer up Kanon, but Chisato refuses the offer. When Keke is alone with Kanon again, she finally expresses the blame she felt over the fact that they had low chances of winning, which would end Keke's school idol dreams, telling her she is just holding her back as she cries, apologizing to Keke. In response, Keke hugs her, pleading her to not talk herself down like that, as she believed in her, because she felt the same excitement hearing Kanon's singing as when she first discovered she wanted to be a school idol. She claims that performing with Kanon is also a dream of hers, as she is a star to her eyes. Inspired by this, Kanon declares that, as Keke believes in her despite her flaws, that she would give it her best in the performance.

The day of the performance, Keke is visibly very scared, but before Kanon can say anything to her, the power is shut down unexpectedly by Sumire Heanna, who was passing by and stumbled on the wires. To show their support, Chisato along with the rest of the audience light up the night with light sticks, which helps both school idols gain her confidence back. Kanon grabs Keke's hand and claims that she can sing, because she is not alone. Immeditately after, Sumire finds a way to bring the lights back on, just in time for the performance of the insert song Tiny Stars. Kanon and Keke receive the special "newcomer award", which allows them to continue as the School Idol Club.

Fanon
KuuKaa is one of the most popular Liella! ships. It quickly became popular, thanks to their chemistry and fresh (in Love Live! standards) interactions, as well as the way Keke was supportive of Kanon. A big portion of the shippers were disappointed that the show's focus shifted over from Keke's relationship with Kanon to Keke and Sumire's relationship after the first three episodes, that the creators had decided to fall back on "using old Love Live! relationship tropes" (aka having a NicoMaki-style relationship in every new generation), feeling that the producers missed the chance to keep doing something new. This was especially reinforced after the 2nd Season's 9th episode. Aside from Sumikeke, it is also rivaled by Kanon's other popular ship ChisaKanon.

It is currently Kanon's most written ship, and Keke's second most written ship on AO3.
