Meet sixteen-year-old Jackie, a girl from the future who has never felt more like the embodiment of failure when her brilliant scientist mother sends her a hundred years into the past to prevent the end of the world—because Jackie is pretty much the only person left alive to do so. But Jackie has never done fieldwork in her life or researched what the world full of viral memes and online trolls was like. And she doesn’t need the mounting pressure of finding strong female warriors that will save the planet when she can’t even find her own dignity.

But “failure” takes on a whole new meaning when, out of desperation, Jackie uses the super soldier serum on four disgruntled guys instead, transforming them into magical girls. And now they refuse to help her because not only do they have to worry about growing a moustache but growing an hourglass figure as well. So what’s a simple girl with a team of gender-swapped boys to do?
