Ayachisa

Ayachisa is the femslash ship between Aya Maruyama and Chisato Shirasagi from the BanG Dream! fandom.

Canon
Aya and Chisato are members of the same band, Pastel✽Palettes; Aya is their vocalist, while Chisato is their bassist. Both of them are third-year students, go to Hanasakigawa Girls' High School, and are in the same class. The two have opposite personalities: Aya is bubbly, sentimental, easily cries, and a dreamer. Meanwhile Chisato is more calculated and professional, knows how to keep her emotions in check, and a realist. Due to their opposite ideals and personalities, the two clashed multiple times in the beginning.

Though Aya had heard of Chisato before, as she is a famous ex-child actress, and was a member of the same agency, 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 - Aya, Hina Hikawa who passed the audition, Chisato, and the model Eve Wakamiya - were going to form Pastel✽Palettes, an idol ban. However, the band has a twist: they are only going to pretend to play their instruments and lip sync while onstage. While both 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. This especially saddens Aya - who had been a trainee idol for three years - because she thought she was going to finally get to make her debut as a real idol.

With a concert scheduled two weeks later, the girls kept practicing and Maya Yamato, who was initially chosen to be just their support drummer until they found someone else, was announced to be their fifth member. When the day of their first concert comes in Chapter 4, the girls are pumped up to perform and start "playing" their first song; however, a major equipment problem happens in front of their audience of 10,000 people, exposing that their band is nothing more than a scam. Both the show and all their upcoming appearances get cancelled, and right after 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.

While the other members keep practicing more than ever, Chisato only shows up to the mandatory lessons, and keep them worried. Secretly Chisato goes to ask the agency staff if she could quit the band. However, the agency staff denies her request, and tells her that leaving the band would most likely cause extreme backlash toward her, and they couldn't be able to protect her then, leaving Chisato to just bitterly accepting the fact she won't be able to escape.

She also starts reacting coldly to people who say how Pastel✽Palettes wouldn't operate as well without Chisato in it, or implying that nobody would care about the band if Chisato wasn't a member.

In the event "Play Act! Challenge*Audition", both Aya and Chisato are called to audition for the same role for an upcoming play. The two keep cheering each other up while practicing hard for the audition, and Aya gives more insight on emotions to Chisato, as well as teaching just how the work "good luck" can be used in multiple ways. The two also end up being able to communicate just through winks and keep telling each other to do their best.

Fanon
Ayachisa is not only one of the most popular ships in both the Eastern and Western fandoms, but also both Aya and Chisato's most popular ship. It is mostly seen as a pure and wholesome ship, though some initially disliked it because they saw Chisato as a cold character.
