Arilisa

Arilisa is the femslash ship between Arisa Ichigaya and Lisa Imai from the BanG Dream! fandom.

Canon
Arisa and Lisa are high school students as well as friends. Lisa is a third-year student at Haneoka Girls' Academy and Roselia's bassist, while Arisa is a second-year student at Hanasakigawa Girls' High School and Poppin'Party's keyboardist. Lisa is very outgoing, gets along with everyone and honest about her feelings, while Arisa is more introverted, struggles with befriending new people and a tsundere.

Someday, A Poem For You: Lisa's Lyrics
The two became acquainted during the event as Lisa goes around asking Poppin'Party, Afterglow and Hello, Happy World! for advice on lyrics writing because she is planning on entering a lyric-writing contest. In Chapter 2, Arisa enters her basement and talks with a Kasumi a bit, before she lets Lisa in. Arisa mentions that Lisa approached her when she was by the school gate, and then asked Arisa to let her come along so she could ask Kasumi about lyrics writing. When Kasumi gets excited, Arisa tells her to calm down and Lisa elaborates how she wants to know just what kind of methods Kasumi uses for coming up with lyrics. They agree to help each other out; Lisa helps Kasumi with a math problem, and when she's done, Arisa tells her "it's your [Kasumi's] turn to teach Lisa-san". After Kasumi explains she pays the most attention to how sparkling and heart-pounding she feels, Arisa tells her she's being too abstract, and how she's not making any sense as she tries breaking down just what it means to her. Lisa uses desserts as an example and Arisa questions why she's talking about them, which Lisa retorts with "I just thought it'd be easier to understand using language I'm more familiar with". At the end of the chapter, Arisa apologizes that Kasumi was only able to explain her method with abstract terms, and then compliments her for being able to understand Kasumi in the end. Lisa thanks Arisa for her cooperation as well before she leaves.

Hectic Happy Valentine's
Aside from being the second major event featuring Arisa and Lisa, the two are also the gacha 4★ pair. During a rehearsal session at Arisa's basement, Kasumi says she'll bake all the Poppin'Party members chocolate for Valentine's, which leads to everyone in Poppin'Party promising they'll give each other chocolate as a Valentine's day gift. A few days later, Arisa is shown browsing through books in the shopping mall and wondering why her first chocolates didn't turn out the same way (after she followed an internet recipe). Lisa then approaches and surprises her, and asks if Arisa is planning on making Valentine's chocolates by herself after noticing what she's reading. After Arisa mentions how Kasumi came up with the gift-swapping idea, Lisa says she's impressed how well everyone in Poppin'Party gets along. She then wonders why her chocolates didn't come out well which leads to Lisa suggesting they make chocolates together. After buying the ingredients, they go over to Lisa's and Arisa is impressed by her kitchen.

Arisa's "Not Bad" Day Off
They are featured as the gacha 4★ pair a second time in this event. Arisa notices Ran and Himari downtown, but is too nervous and afraid to approach them. She is soon joined by Rimi and Lisa, who tries calling out to them, but Arisa blocks her from doing so and says she hasn't mentally prepared herself yet. Lisa calls her cute and asks if the two want to get to know both Ran and Himari, and they then proceed to the local family restaurant where Lisa gives them a special lesson on communication.

They also mention each other in their card stories' Special Episodes. In Arisa's, titled "Open Your Heart", she mentions that she wasn't as nervous around Lisa as she was with Ran and Himari, and how they had the conversation simulation. In Lisa's, titled "My Precious Friends", she talks about her friendships, how her friend circle's expanded suddenly and how she's realized just how important they are, before coming up with a plan of calling Rimi, Arisa, Sayo and Yukina to hang out with her.

Fanon
Arilisa, similarly to most ships that aren't KasuAri or Yukilisa, is a rarepair. Fans of the ship enjoy the way Lisa takes care of as well as pushes and supports Arisa to express her true feelings (which most often leads to Arisa blushing or denying things in the tsundere fashion).
