Higurashi no Naku Koro ni Kira

Wacky hijinks abound as Rika finds herself in a parallel Hinamizawa in which Tokyo is made of superpowered henchman and Rika herself is a magical girl. After returning to her regular Hinamizawa, Rika finds that the time line has not completely straightened out, as her younger self from 4 years prior has accidentally come to the future.
