Mashikasu

Mashikasu is the femslash ship between Mashiro Kurata and Kasumi Toyama from the BanG Dream! fandom.

Canon
Mashiro and Kasumi are fellow vocalists of their bands as well as good friends.

Before Morfonica was officially added into the game, Mashiro was first seen in Main Story 2 Chapter 8. As Poppin'Party heads to Livehouse CiRCLE's lobby, they spot Mashiro there and Kasumi recognizes her as the girl they talked to after their mini-concert. Kasumi says she remembers her because of her school uniform, and decides to go to talk to her with Tae. Mashiro recognizes them as well, but stays quiet when Tae asks if she still wants to be in a band. Kasumi notices her taking down the poster she made for recruiting band members, asks why she's doing it and Mashiro tells her she doesn't want to be in a band anymore. She then tells the two how she's never going to come back to CiRCLE and makes her way out, leaving Poppin'Party and especially Kasumi in a disheartened mood. In the next Chapter, Kasumi wonders why Mashiro would say she hates being in a band when she herself has always a great time when practicing. She then gets a surge of determination and now set on performing even more and better so she can convince Mashiro and show her how fun bands are.

Fanon

Trivia

 * Although not confirmed by Craftegg nor the official authors, it is heavily believed that Mashiro is supposed to be a new iteration of the original storyline's Kasumi, who had a very similar personality - she was also extremely timid, depressed and had very low-self esteem before an event that moved them and caused them to change (in Kasumi's case, finding Random Star and meeting Arisa, and in Mashiro's case, seeing Poppin'Party perform at CiRCLE).
