A doujin game by Nuu based on the Touhou Project series.

A phantom treasure said to have been buried by pirates a long time ago.

Although stories were passed down, there was no one to follow the legend.

Then, word got out that the treasure had been discovered by chance in a certain place.

With a shovel in hand, Flan and her friends set off on a journey through the forest and across the plains, sometimes running into bad guys, and sometimes getting into a bit of mischief.
