Umagoya Princess

There is a small country called Mandamin.
A civil conflict has destroyed this country. During the war, the seal of the dungeon hidden in the castle was released and the country received many adventurers.

In the autonomous area of adventurers, the princess who was officially missing lived as a fugitive.
When her real identity was found, she thought that she was going to be killed, but instead, the adventurers protected her.
Without authority and power, she wished to become useful to them...
