Kaorimi

Kaorimi is the femslash ship between Kaoru Seta and Rimi Ushigome from the BanG Dream! fandom.

Canon
Kaoru and Rimi are both high schoolers; Kaoru is a third-year student at Haneoka Girls' Academy, while Rimi is a second-year student at Hanasakigawa Girls' Academy. Kaoru plays the guitar in her band Hello, Happy World!, while Rimi serves as Poppin'Party's bassist and composer.

The Impromptu Wedding Dress
Their first major interactions happen in this event, where Rimi's bandmate Saaya is roped into a wedding photoshoot together with Kaoru at the recently opened wedding hall. When Saaya finds out that everyone in Poppin'Party came to watch her getting photographed, Rimi notices Kaoru and praises just how handsome she is. Kaoru laughs, before calling her a "lovely kitten" multiple times, and telling her "Your cheeks are as bright as the reddest of my apples, how adorable. I might just have to take a bite...", which causes Rimi to stammer and leaves her blushing and dazed. Afterwards, Rimi ended up becoming one of Kaoru's big fans, with her blushing around the latter and calling her wonderful, even when she's just mentioned by someone else. She then starts frequently attending Hello, Happy World!'s concernts and Kaoru's plays, especially together with Afterglow's bassist Himari, who is also a huge fan of Kaoru's.

In Rimi's 4★ card story titled "Kaoru's Costume", she and Saaya are talking at the CiRCLE Café before being joined by Ako. The three proceed to talk about the wedding photoshoot, and Rimi mentions she thought Kaoru looked so cool and dreamy she couldn't take her eyes off of her. The three then make plans to go see one of Kaoru's plays and imagine how she could make any clothing look good. In the special card story titled "Wedding Poster", Rimi talks to the Player Character and describes just how wonderful Kaoru looked, while accidentally blurting out that she was jealous of Saaya wearing a wedding dress and walking with Kaoru in her arm, and wishing how she wants to do the same, before embarrassedly telling the Player Character to forget what she'd just said.

In Kaoru's 2★ card story titled "Wedding Redo", she runs into Rimi at the park as she is practicing her lines for her next play. While chatting about what both of them were doing, Kaoru calls Rimi a kitten, which causes her to get flustered, before she continues talking. She then blurts out that Kaoru looked fantastic in the tuxedo she wore during the photshoot, after which Kaoru thanks her, and Rimi thinks just how wonderful her smile looks like. Kaoru then asks if something's wrong, leading to Rimi once more blurt out she wishes that she were Saaya's position during the photshoot so she could've taken pictures with Kaoru. Kaoru then proposes they scurry over away to the wedding venue right away, borrow a dress and a tuxedo and have a, as Kaoru says, "wedding rewritten." Rimi gets completely embarrassed, and Kaoru ponders whether she's not suitable enough for Rimi, who then proceeds to say she has other business to take care of and runs away, with Kaoru chuckling and comparing her to a shy kitten.

Summer, Slow Summer
Rimi, alongside with Eve, Tomoe and Saaya get invited by Kaoru to spend three days at her uncle's cottage. In Chapter 1, Rimi speculates that Kaoru is going to make a grand entrance at the horseback riding club, and she in fact comes to them while riding a white horse. She then, alongside with the special trainer, host a horseback riding lesson for the others as they go trail riding. Rimi is nervous about getting on the horse, fearing she might be too heavy for it, before Kaoru helps her get on its back, while Rimi is blushing over the fact she got to hold Kaoru's hand.

Other than that, the two have not had many major events together.

Anime
In BanG Dream! 2nd Season, during the first episode Rimi gets completely flustered after she and the rest of Poppin'Party watch Kaoru enter the backstage. In the 4th episode, where Hello, Happy World! invites Poppin'Party to the party cruiser in order to inspire and cheer them up, Rimi gets taken away by Kaoru, and carries her around the ship as the other four chase after the Hello, Happy World! members. The trip ends with Hello, Happy World! performing in the sky while Kaoru trembles in fear (due to her fear of heights). When they get down to the cruiser, Rimi holds the distraught Kaoru in her arms, before she passes out.

Fanon
Though ultimately a rarepair, Kaorimi has had a fair share of supporters in both sides of the fandom. Despite their canon dynamic, plenty of fanartists have drawn Rimi being the assertive one in the relationship.

The ship has also caused Western fans to fight over Rimi's sexuality (which has never been confirmed in-canon); some fans speculate that a big part of why Rimi is so fond of Kaoru is because of her masculine personality and appearance, implying that she is bisexual, while some argue that headcanoning Rimi as anything but lesbian is homophobic.
