Zombieland Saga. In the first episode, a schoolgirl want to sign up for an idol audition, She exits her house, form in hand, intending to drop it off on the way to school... and gets hit by a truck less then five seconds later.

And then she wakes up ten years later to find that she's a zombie(with no memory of her previous existence) who was reanimated by a idiotic pretty-boy necromancer along with several other "legendary" girls in order to form an idol group to bring attention to the prefecture they reside in.

Yeah. It's weird. But good.
