This new play is actually a reboot/revisioning of the previous YoRHa Boys Ver.1.0 play that first debuted early in 2018, and the novelized version was recently released in English. The YoRHa Boys Ver.1.0 and YoRHa Girls Ver.1.1a share the same, overall narrative, but this one is a gender-swap of the originally all-male cast along the same lines as the YoRHa Ver.1.3a/aa plays (remember the “a” stands for “arranged version”).
