Chisahina

Chisahina is the femslash ship between Chisato Shirasagi and Hina Hikawa from the BanG Dream! fandom.

Canon
Chisato and Hina are members of the same band, Pastel✽Palettes; Hina is their guitarist, while Chisato is their bassist. Both of them are third-year students, however they go to different schools (Hina goes to Haneoka Girls' Academy, and Chisato goes to Hanasakigawa Girls' High School). The two have different personalities: Chisato is mature, calculated and hardworking. Hina is very bubbly and friendly but also a genius who has a hard time understanding other peoples' struggles, and tends to be brutally honest.

The two met for the first time when their agency called them for an emergency meeting in their First Band Story. During the meeting they revealed that the four of them - the trainee idol Aya Maruyama, Hina who passed the audition, Chisato, and the model Eve Wakamiya - were going to form Pastel✽Palettes, an idol band. However, the band has a twist: they are only going to pretend to play their instruments and lip sync while onstage; this is revealed after Chisato mistakes Hina for a backup artist. While Aya and Eve were against the idea, Chisato quickly accepted it, saying how nobody comes to see idols for their musical talent, but rather for their appearance and personalities. Hina proceeds to remark how she's the only one who can actually play, but finds the idea of faking playing fun in its own way. In the next Chapter, Hina and Chisato interact for the first time; Hina tells the latter she's looking forward to working with her, and then says she didn't except them to have a celebrity in their idol band. Chisato smiles and tells Hina she's still got a lot to learn, and how there must be a reason why the agency wanted her specifically in the band. This leads to Hina countering how, despite all the experience she has, Chisato might be as unsure as the others. After Hina leaves, Chisato mumbles how she just wants to succeed and nothing else. In Chapter 3, as the girls are trying their outfits, Hina says hers fits perfectly, and is surprised to hear as Chisato tells her they're testing their outfits to see if the staff members need to fix or adjust anything.

In Chapter 5, after the major equipment problem that happened during their debut concert, the girls as well as the agency are unsure of the band's future. Chisato starts wondering whether she can stay in the band, as she believes that the band has completely failed and has no future at all, not to mention the scandal could tarnish her image. As Chisato goes to talk to the agency staff, Hina gets bored waiting for her and encounters her in the hallway conversing with a staff member. After the two are finished, Hina approaches her, and asks what they were talking about. Chisato reassures she was just inquiring what went wrong, and how the concert's failure was a huge problem but also a way for the other girls to grow stronger, so strong that they won't need Chisato around. Hina ponders what Chisato meant by that, but then returns to the other band members.

After Aya stubbornly sells tickets in the rain and Chisato runs to help her out, the two return to the agency, and the other three are overjoyed to see them coming back together. Chisato sneezes and Hina jokes about Chisato catching a cold. She then proceeds to question what made Chisato have a sudden change of heart, which Chisato answers with, "I was just worried about Aya-chan. That's all." Hina then asks how Aya-chan was, Chisato says "She was how she always", and Hina gleefully proclaims how other people having different personalities makes them so interesting.

In the "When the Flowers Bloom" event, like the other band members, Hina is surprised but also happy to hear that Chisato had managed to get a role in the famous director Takayuki Miyagawa's upcoming play. When the other four go watch her practice and Miyagawa keeps interrupting Chisato's performance, Hina thinks that his way of yelling and interrupting Chisato is more intense than she'd expected. During a break they go and tell Chisato that she shouldn't worry too much and how she's a pro, so she'll definitely be fine. However, after Hina says that she's surprised that Chisato has her struggles and how she expected the latter can do anything without even trying (which she also calls weird), Chisato explodes at the other members and tells them to get out. After they leave, Hina wonders if it was her fault that Chisato's mood got even worse. In the next Chapter, Hina says she didn't mean to make Chisato angry, and after talking with the other three, realizes that Chisato works more than they realize, and that they were unintentionally putting pressure on her. In Chapter 5, after Chisato apologizes to the other band members, they go to a cafe and Chisato shares more things about herself, to which Hina comments how she's never seen Chisato being so open about herself. A month later, their rehearsals for the play is over and Hina tells Chisato that she was so glad the play had a happy ending, as they didn't see it during the rehearsal. She then suggests they take a picture to commemorate the day and upload it on their blog. After taking the picture, Chisato remarks that she will use it as her screensaver, which surprises Hina, as she would've never imagined the old Chisato would've done something like that, and compliments her for managing to change.

In Hina's 2★ gacha card from the same event, "Backstage", she interacts with Chisato in the first episode, and mentions her and the recent events in the special episode to the Player Character. In the first episode, which is titled "Sister Troubles", Hina locates Chisato in their talent agency's hallway and starts asking her about the latter's younger sister. When she learns that Chisato and her younger sister share things with each other and get along well in general, Hina states she wishes her relationship with Sayo would be as good, and then asks what does Chisato's sister need to do to make her happy, because she wants to hear it from "an older sister's point of view". Chisato then suggests they come up with a strategy which would lead to Hina and Sayo getting closer; after Hina lists off Sayo's interests, Chisato says they [Hina and Sayo] could go to a dog café, or even visit some sweet shops Chisato knows of. Chisato proceeds to help Hina with her planning. In the second episode, Hina encounters the Player Character in the fast food store and proceeds to tell them all about Chisato's struggles, and how she truly hadn't expected for Chisato to have it so hard. She then says "I'm not sure how the whole 'effort' thing works, but maybe people that work really hard like Chisato-chan are best suited for that kind of job," and how she was so happy for Chisato getting a huge round of applause during the curtain call. Hina then realizes that "Having people recognize you after putting in all of that hard work must be nice~. Thinking about it like that, maybe effort is a good thing", and declares she'll ask Chisato about it the next time they see each other.

In Pastel✽Palettes' section of the "Backstage Pass" event, Hina says she's bored of waiting for their show to start so she says she'll step outside for a bit, which the other members stop her from doing so. Chisato scolds her for wanting to do so, because "The last time you took it upon yourself to 'step outside', one of the audience members spotted you and it became a huge headache". Hina says she knew everyone would decline, so she secretly brought Sayo's clothes with her to use as a disguise. Chisato says Sayo would most likely be furious after finding out, and after Maya compliments how similar they look because they're twins, Chisato sighs and says she still talks like her normal self. In the next Chapter, as the girls are reflecting on their performance and talk about each other, Hina says it's fine for people to stay the change, because it'd be boring if they'd just keep changing. Chisato asks if it would be better if they continued improving themselves, which leads to Hina using Aya as an example, and Chisato agreeing with her that Aya becoming perfect at improvising and singing would be boring.

In Pastel✽Palettes' Second Band Story, titled "Luminous Once More", the band's agency starts pushing the band members more towards their solo projects, leading to them having less time to do band-related activities, or even practice together. In Chapter 5, their agency staff reveals that Pastel✽Palettes is going on a hiatus, and say that they'd like to think Pastel✽Palettes as a place they can always come back to, in case their solo careers fail. Hina then goes on to say that she doesn't care, as she thinks everything has been so boring to her lately, because everyone is only focused on their solo projects, which she sees as them admitting that they don't care about the band anymore. Chisato later laments the fact that she wasn't able to counter Hina's words, other than denying that they're unwilling to be in Pastel✽Palettes anymore.

The two also have a bit of a rivalry. In one of their Live Interactions, Chisato laughs before telling Hina that she can't afford to lose to her. Chisato is also shown to reprimand Hina for not doing certain things, such as not practicing her lines for a play more than once (which led to Hina saying she remembers the whole script already), for her brutal honesty, and in the beginning, for not understanding how the idol and entertainment industry works.

Fanon
Chisahina is more of a rarepair. The two are shipped with the other girls more frequently, not to mention some people in the Western fandom saw their relationship (and the two girls as well) as toxic initially due to their plotline in the First Band Story.

Trivia

 * Hina likes making fun of Chisato's drawing skills (as the latter is quite bad at it).
 * In one of Pastel✽Palettes' lounge conversations, Aya suggests the five go somewhere after practice, which leads to Hina telling she wants to go out to a "boppin' place". Chisato is the first one to suggest that they go to a planetarium, which Hina declares to be a boppin' idea.
