Kyôsôgiga— Episode 1

Everything was peaceful until Myoue and Koto suddenly vanished. Their three children are left to take care of the city, and Yakushimaru inherits Myoue's name and duties. Stranded in this alternate world, their problems only get worse when a young girl-also named Koto-crashes down from the sky and declares that she is also looking for the older Myoue and Koto. Armed with a giant hammer and two rowdy familiars, Koto just might be the key to releasing everyone from the eternal paper city.
