YuuPomu

Yuupomu is the femslash ship between Yuu Takasaki and Ayumu Uehara from the Love Live! fandom.

Love Live! Nijigasaki High School Idol Club
Yuu and Ayumu are childhood friends and neighbors. They are incredibly close, walking to and from school together every day and going shopping after school often. It is shown that Yuu wakes up every morning by a call from Ayumu. After seeing a performance by Setsuna Yuki, both girls are entranced by school idols and decide to join the club- Ayumu as an idol, and Yuu as a supporter. Ayumu performs a song to Yuu on the stairs of their apartment complex called 'Dream with You.' Throughout the season, Ayumu is seen getting jealous of other girls when Yuu focuses her attention on them. This is heightened in episodes 10-11, when Ayumu sees Setsuna Yuki trip fall onto Yuu, and she thinks they are hugging. Ayumu gets very jealous, and in the next episode the girls have a conversation about it. Ayumu asks if Setsuna is more important to Yuu than her, and she quickly says no. Ayumu asks Yuu to "just belong to her." In the episode after, both girls apologize and Yuu gives Ayumu a flower representing feelings that never change. The girls hug and go home, holding hands, and Ayumu sings another song paralleling Dream with You, called Awakening Promise.

Love Live! School Idol Festival: All Stars
In the LLSIFAS story, the player is close childhood friends with Ayumu Uehara. The player can enter their own name into the game, but her name has been revealed to be Yuu Takasaki. In the story, Yuu invites Ayumu to be a school idol since she admires her. Ayumu also shows signs of jealousy in the game, though not as much as in the anime. When picking out a gift for Yuu with Shioriko Mifune, Ayumu says that she adores her and wants to thank her for all she does for the idol club. Ayumu and Yuu respect and admire each other a lot, often complimenting the other.

Fanon
This ship sailed due to the girls being such close friends, and the childhood friends trope being so popular. The ship is the most popular Nijigasaki relationship tag on Ao3. It is sometimes rivalled by SetsuYuu, SetsuYumu, ShioYumu, etc.

Trivia

 * Yuu Takasaki originally didn't have a name, as she was just a player character, so some early content of the ship refers to her as "Anata."
