Dungeons are the stuff of dreams. Defeat the monsters, take their loot, and then venture into uncharted territory to discover hidden riches. Tina, an upstart adventurer with just such a dream, ends up mortally wounded while exploring a dungeon. Suddenly, the great demon known as the Beast King Garon, who was supposed to have been slain by a hero in the distant past, appears before her! Dungeon fantasy meets medical drama.
