Aririnko

Aririnko is the femslash ship between Arisa Ichigaya and Rinko Shirokane from the BanG Dream! fandom.

Canon
Arisa and Rinko are both members of the Hanasakigawa Girls' High School student council. Arisa is the keyboardist of Poppin'Party, an introvert whose hobbies include tending for bonsai plants and internet surfing. Even though she's basically a shut-in and admits to being lazy by nature, she still manages to achieve excellent results in school due to her intellect. Rinko is the keyboardist of Roselia, and a shy and socially awkward girl who was initially too frightened to speak in front of others, let alone perform before them. She has a tendency to stutter when speaking, and usually keeps quiet until she feels comfortable. Their personalities are similar: they're both awkward in their own way.

Their first proper interaction happens in the School of Flowers, Away in a Corner event. In Chapter 1, Rinko talks with Sayo and Kanon about wanting to overcome her fear of interacting with people. Rinko says she wants to talk with Arisa, and Sayo and Kanon agree they would be a good match.

In the Chapter 2, they talk in the courtyard about Kasumi and Ako, their respective best friends. Kanon comments they're hitting it off pretty well, and Sayo agrees. Arisa asks about the book Rinko was talking about and said it sounded interesting. Sayo says this is a good opportunity for them to spend more time together and they agree to go to the bookstore together. When they get to the bookstore they find it's closed, right after running into Kasumi and Ako who ask them to go to a restaurant together.

In the Chapter 3, The next day, Rinko talks about how she felt like a bother to Arisa, Kasumi and Ako. Kanon reassures her and says her and Arisa hit it off pretty well. Sayo agrees. Rinko decides to apologize, and Arisa responds saying she should be the one apologizing. After this, Rinko feels like she made Arisa worry and Arisa tries to lighten the mood with self-deprecating humor, but Arisa realizes Rinko's too caring to find that sort of humor funny. Arisa notes the conversation is going nowhere and both of them leave off on an awkward note.

In the Chapter 4, Arisa and Rinko are doing student council work while the atmosphere is awkward. They both want to reconcile, but both get interrupted by teachers and other school staff giving them paperwork to sort out. They work together to handle the amount of paperwork they were given.

In Chapter 5, Rinko talks about becoming the student council president to overcome her fears with Arisa, and Arisa says it's admirable. Rinko talks about her insecurities. She thinks her story is boring, but Arisa says it wasn't boring at all.

In the last chapter, they talk about how much they've grown as people. Arisa says they're both awkward in their own way, and that she's shy just like Rinko. Rinko tells Arisa they should work towards their goals together. The event ends with talking to each other about student council work the day after, Misaki and Kasumi commenting they get along well.

In Arisa's 4★ gacha card from the same event, "Into a Steady Secretary", Arisa talks with Ran about being nervous around her and Ran helps her with texting Rinko.

The two are friends and have 6 area conversations.
