Mink was born to a man who used to be a skilled swordsman and a female imperial red dragon. At age fifteen, she fell in love with a singer named Dick Saucer but because he is also a dragonslayer, she has no choice but to get a potion that can change her into a pure human. She can only get the potion, however, if she can slay the most powerful Demon Lord in the land, Azetodeth and go to his palace known as the Demon King's island. Not only does she have to reconstruct the gourd of the saints, an item that can seal Azetodeth, she also has to be aware of Princess Vina, her rival for Saucer's affections. Mink is aided by her friends Lufa, Pia, and a fairy mouse named Mappy, on her quest.
