Boukoku no Oujo to Goblin no Mura

Princess Ashe gets separated from her companions, and encounters goblins in the swamp. Will she manage to escape and reunite with her friends? Will she be accepted as a goblin warrior and wait for an opportunity to escape? Will she be kept as the goblins' pet? Or will she abandon her mission and join the goblin tribe? Her fate depends on your choices.
