Tsukuchisa

 is the femslash ship between Tsukushi Futaba and Chisato Shirasagi from the BanG Dream! fandom.

Canon
Tsukushi and Chisato are both high school students as well as members of their own bands; Tsukushi is Morfonica's drummer and leader, while Chisato is Pastel*Palettes' bassist. While Chisato is a third-year student at Hanasakigawa Girls' High School, Tsukushi is a first-year student at Tsukinomori Girls' Academy, a prestigious school filled with talented individuals. Chisato is calm, rational, and very professional, stemming from her experience as a child actress. Meanwhile, Tsukushi is more energetic and emotional. Although she works tirelessly to be recognized as a reliable person, she is ultimately clumsy and tends to get flustered, especially when she's being teased.

Blossoming Symphony
Their very first interaction happens in Chapter 3, where Tsukushi and Nanami spread out and attempt to strike up conversations with the other bands at the hanami party. When Tsukushi tells the others that she is used to being the band's leader because of her position as the class president and whatnot, Chisato says she must be trustworthy enough for her to be given an important job like that. Tsukushi denies it, and then asks if Chisato manages Pastel*Palettes after Hina says she's like Chisato. Chisato responds, saying she's responsible because of her status as a long-time actress but denies her title as a manager. While watching Hina, Chisato and Sayo talking about the things Chisato does for everyone, Tsukushi thinks how mature and responsible Chisato is and how cool she looks despite being as short as Tsukushi. Chisato asks Tsukushi if something is wrong, and the latter blurts out how she's so impressive and why it makes sense she's Pastel*Palettes' leader. Hina and Chisato are surprised before correcting that Aya is their leader and how "it's a job only she can do." Tsukushi is surprised once more, says she can't believe Chisato isn't the leader considering how trustworthy she is, and how Aya must be even more skilled, causing Hina, Chisato and Sayo to start laughing. The Chapter ends with Tsukushi asking if she did something wrong.

Girls be ambitious!
After talking about Nanami's part-time job with the other Morfonica members, Tsukushi starts wodnering if she should get a part-time job as well.

In Chisato's Card Story's Episode, titled "Things You Can Understand As a Regular", Chisato is greeted by Tsukushi upon entering Hazawa Coffee. After sitting down and Tsukushi offering the menu for her, Chisato sighs and Tsukushi asks if something is wrong. Chisato apologizes and mentions how she might still be tired from having to stay overnight at the filming location. Tsukushi is shocked and remarks that it must be hard for actresses and idols. Chisato mentions while it is not a new experience to her, this time the travel time was longer than usual which led to her feeling tired. Tsukushi suggests Chisato to order something sweet, and Chisato agrees but mentions she was only going to order tea, and just how smoothly Tsukushi managed to suggest it before saying it's just a joke. She then asks Tsukushi what her suggestion would be, as well as which tea she would recommend. Chisato is surprised to find out Tsukushi knows which tea would go well with the cake, leading to Tsukushi revealing she started studying different combinations on her own because customers would usually ask her for them. Afrer saying she wants to help Hazawa Coffee become even better, Chisato suggest they should add a note about the combinations to the menu. Tsukushi is overjoyed hearing her idea and mentions she'll bring it up with Tsugumi when the latter returns. Chisato is happy for her, and Tsukushi thanks her for her help, saying Chisato is amazing and how she could've never come up with an idea like that. Chisato in turn says she should be thanking Tsukushi instead, and how watching Tsukushi working hard managed make her fatigue go away. Tsukushi blushes and after Chisato decides on her tea order, Tsukushi runs back into the kitchen and Chisato mutters how she's gonna do her best as well.

In her Special Episode, titled "Tsukushi's Influence", she runs into the Player Character at the station entrance and tells them she's on her way to Hazawa Coffee. Upon finding out that they had visited Hazawa Coffee as well, Chisato asks if they think the place has become more livelier before saying it might be all thanks to Tsukushi. She mentions seeing customers smiling after talking to Tsukushi and even when she's just watching her working from the sidelines, she wants to keep supporting her so she can keep working hard. She then tellls the Player Character how she kept fumbling around when she started, but also how empty Hazawa Coffee would start feeling if Tsukushi quit her part-time job.

Fanon
Tsukuchisa is a huge rarepair, mainly due to the fact that Morfonica was so added so late into the game, how both have more popular ships, and because of their limited interactions. It is mostly shipped platonically rather than romantically. Some have called it "discount Ayachisa" due to Aya and Tsukushi's similar personalities and appearances. Aside from that, some have also joked that Tsukushi is actually Ayachisa's future daughter.
