Mabayu, a recluse who currently takes residence in Mitakihara City in the attic of her aunt's bakery, is a middle school second year with a love for the world of movies, often finding herself staying up long past her bedtime just to binge entire trilogies. But she's unaware of many things. One, that she's living in a city of Magic Users. Two, that she IS one herself, third, probably worst of all, is that she heralds a danger no warrior could ever dream of fighting - she is fated to become Walpurgisnacht and bring ruin to all of Mitakihara, and later, the rest of the world (in THIS story, at least). Mabayu cares not to improve her social life, but with travesty on the horizon, she may not have a choice.

While she has no official English VA, you can her a sample of what she sounds like in JP from here: https://www.youtube.com/watch?v=6XNHBuL1MDM
