In the year 5239, the world is modern, yet under the rule of monarchies. Kings, queens, princes, and princesses govern every nation. It all began in 2034 when a massive oil drilling operation started in Russia. Determined not to be left behind, America began its own drilling efforts, pushing deep into the Earth's core. This reckless pursuit unleashed something unimaginable: magic. Mana and magicules surged from the core, altering the world forever.

The release of mana awakened the Four True Dragons, ancient beings of immense power. White Death emerged in Japan, Crimson Red in Germany, Hellish Tundra in America, and the strongest of them all, the Sun God, remains sealed within a hidden dungeon. Although the Sun God slumbers, the dragons' minions, powerful wyverns, now roam the earth. Conventional weapons, like bullets, are useless against them, deflected as if they were mere BBs. Only magic can harm these creatures, leaving humanity vulnerable. Armies struggle, but magic-users and ancient arts offer the only hope of defense.

You are one of the True Dragons: White Death, a being of majesty and power, sowing chaos across Japan. Wherever you go, destruction follows. That is until one fateful day, when you encounter a young girl with pink hair, wearing a priestess kimono. She seems harmless—a mere child—but something about her makes you pause. In a moment of arrogance, you lower your guard. Before you can react, she begins to chant. To your horror, she is a dragon tamer. Her magic seals most of your immense power and, even worse, transforms you. From a fearsome, manly dragon, into a girl. What will you do now?
