Ururun Quest: KoiyuukiUrurun Quest: Koiyuuki

This is a world where humans and beings called magic creatures exist.

Once the world was one, but suddenly one day a rampant fog divided the world. The fog covered the sea and the sky, the people's movements were hindered. Before long the people had to think about living in a reduced sphere of habitation.

This situation continued for many hundreds of years. The people spread out and built towns on various plots of land where they quietly started to live. People that were curious about the outside world and other continents were practically extinct.

Soi, the town where flowers bloom wildly, is the town where the protagonist lives.

She's a girl that is full of energy and curiosity. For her summer vacation research project assignment she started thinking that she would like to investigate the things outside of the town. However, outside of town the mist has become even thicker, and dangerous monsters have appeared.

The protagonist with unrestrained curiosity, along with the cooperation of her childhood friends Tsukishiro and Shuka, step forward outside of the town. They have no idea what could be waiting for them at the start of their great adventure.
