Ditzy Nana, fujoshi Chiwa, idol wannabe Kaeru, and goth groupie Kai are single salarywomen in their upper 20s, but just because the friends have jobs to juggle doesn’t mean they can’t also have fun! By spending their weekends and free time going on awkward group dates, imagining ridiculous yaoi scenarios, and flirting with ultra-buff bodybuilders, the women are sure to have a great time and create plenty of memories in the process!
A "shirobako" refers to the white box into which a finalized tape of a film is put, full of the effort of everyone who worked on it. Five girls have their eyes set on getting in a white box as they try to find success in the anime industry through writing, production, and voice acting.
Both anime are comedic workplace anime with female leads, focused on making manga and anime, respectively. They both have big casts, and tackle roughly the same issues, like keeping deadlines, dealing with creators and the inner workings of the business.
Mangirl! is more zany, whereas Shirobako is more grounded, but they should both be enjoyable for those who want more of an insider view into anime and manga.
