Banished Noblewomen Pioneer an Island! They'll rise to power through magic stone mining, developing tourist destinations, and trade!

The long war with the neighboring country finally ended. As a condition for peace negotiations, Ashia Foregandros, the only daughter of Duke Foregandros, former general of the Gills Kingdom Army, was unjustly branded a war criminal and sentenced to exile on an island.

Left alone on the uninhabited island of her exile, Ashia nonetheless desperately tries to survive. After some time, Milos, a former mercenary of the neighboring country and a werewolf, who was also exiled in similar circumstances to Ashia, washes ashore on the island. Ashia and Milos help each other, and despite some inconveniences, they continue their enjoyable life on the uninhabited island together.

From then on, various people, such as witches, monster tamers, and apothecaries, who were deemed a nuisance by both countries and exiled, wash ashore on the island. Ashia cooperates with them to pioneer the island, sometimes fighting against monsters living there or making them allies, repelling invading pirate ships to free slaves, or for some reason even befriending pirates...

Ashia and her companions steadily pioneer the island, discover magic stone resources hidden within, engage in trade with other countries, and use the earned funds to develop beach resorts, gradually advancing the island's development. However, a warship from the Gills Kingdom, aiming for the resources, attacks them...!?

“I am Ashia, daughter of General Foregandros! A spineless fleet not commanded by my father will be scattered before they even manage to land!”
