Fura-fura Bouken Flan-chan: Kaizoku Zaihou Tanken-tai

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.

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