Haiyi's Rainbow Bridge

This is Haiyi, the second-largest city in Nanji Province! The world's best travel destination for couples! It has the sea, all kinds of theme parks, and, of course...

...magical girls!

This is a Madoka Magica fanfic I wrote a few years ago. None of the original characters appear, but it uses the same world setting.

It's very short! The plot is terrible! There are only three volumes, and it all ends after about 150,000 words!
